Title: Training different energy systems
Post by: mrjonathanr on January 23, 2022, 06:12:21 pm
Belatedly, I have become more interested in this. Here's Alex's pdf and a few links I found helpful:
https://www.trainingbeta.com/wp-content/uploads/2015/05/1.-Alex-Barrows-Training-Doc-V2-for-training-beta.pdf

https://www.thesustainabletrainingmethod.com/tstm-blog/2018/8/28/energy-systems-survive-thrive-perform
This is the first of 5 blogposts. I found reading them as a set helped to understand how energy is produced in muscle.

Tom and Ollie's site:
https://my.crimpd.com/workouts

My end goal is getting on the sharp end of some difficult (for me) trad and knowing there's something in reserve when I'm gripped  And that means building capacity over a good length of time.  I get the lattice stuff and the methods in that section of their site, but there's so much knowledge and experience on ukb I wanted to put a question out there:

What would people recommend as a way of training Anaerobic Capacity? Especially the short, powerful end? Ideally using a bouldering wall or even better, a board. In other words, what do people find really worked for them?


Thanks

Laddering  up and down on a set of the same sized holds for 30 moves on a 30  degree board (feet on) worked for me

As you get fitter reduce the rest time until you can rest for less time than it takes to do the 30 moves

Once i could do 20 sets with the same rest time as work time I made a slightly smaller set of holds and started again

I had 8 rungs with about a foot inbetween them , skipping rungs also was good as a switch up but i could never do many sets in a row doing this as you are doing a lot more climbing for 30 moves

Managed to build enough power endurance to onsight some soft 7b sport routes with 4 months of doing this twice weekly

Basic principles for ancap training:

1) climbing time about the same as rest time
2) around 1.5-2 mins duration
3) hard enough to (not quite) fail on last rep of last set.

So something that’s worked really well for me in the past is to set a 15 move Boulder problem on a steep board and do 4 reps with ~2 mins rest. This is one set.

3-4 sets, with 5-6 mins between sets.

But basically anything that hits the principles above.

Thanks for the replies, both.

Devonshire, that sounds like quite a beasting, but possibly overlapping aerobic power? ie the ability to keep going through high levels of lactate. Did your 30 moves take over 90 seconds to do? I guess you got faster too?

Stu, that's basically what I have been doing of late.

Logically, from what I get of the literature, rest times should be much longer, as the aerobic pathways won't have fully converted lactate back into pyruvate and nad+ to allow the glycolytic pathway to fully recover in that amount of time
ie it seems like rest times should be significantly  longer than work times if anaerobic capacity is to be properly trained and by longer, I mean 4x, 6x, or 8x longer than work periods

Yet knowledgeable people seem to prefer to create sets with insufficient recovery between reps and better recovery between sets. That would seem to overlap with creating a tolerance for lactate (or rather H+ in the cells).

Obviously experience trumps half-arsed understanding- which is why I asked!

Stu, so your 15 move boulder was taking you over 90 sec to climb? This seems really slow, even for shark.

I don't understand what you've written at all here Stu, since 15 move problems inside don't usually take 1.5-2 min, that time length sounds way longer than what I (and I'd assumed you) do for ancap, and your rest time sounds really short. Your principles sound v different to what I do but your session sounds v similar (I use a 3 min interval timer, normally about 45s climb and 2.15 rest, give or take). Have I misunderstood what you meant or have you changed format or started to climb slow?

I would not describe what Devonshire is doing as an cap at all really. Unclear to me if this is simply an issue of nomenclature.

My fave is long boulders similar to Stu. Also like boulder tripples - 3 boulders (~6 moves each); I use on-the-minute but think lattice do 1 min rest so more like a 1.20 interval timer. Rest maybe 3-5 min between sets. Think it's on crimpd app. This is a bit more strengthy so fits well with the short and powerful end IMO. Also since it only needs short up problems it's v easy to reuse problems you already have made up and know

Whatever you do Jonathan, take it easy to begin with and get plenty of recovery rest after your session. I kicked up the gear of AnCap (15-18 moves, 2-4x rest) and it started to fry my elbows / brachialis/brachioradialis pretty quickly.

Anyone done AnCap on the lead wall?  I was trying to use a project level route, split into 3 sections (25m wall) and just gunning for the 15-18 move length, with decent length hangs on the rope between sections.

Oh yeah, forgot to ask. All you seasoned energy systems / periodised climbers - how badly does your route climbing ability usually drop off in the middle of a longer AnCap block?

I.e. say you peak at, f8a onsight level but halfway through an 14 week AnCap block (with lots of strength work but not a lot of aero), would you expect to drop down to f7c level, or worse? 7b+? 

My peak form just now is around the f7b o/s level and I'm looking to up that to f7c, but had a session (after 2 weeks no climbing due to tweaked wrist in a silly fall walking back from a winter route..)  but I got pretty shut down on a f7a+ at ratho on Friday, and one of the f6cs felt pretty hard!

Post by: mrjonathanr on January 23, 2022, 07:40:32 pm
Thanks Alex, that fits more with what I’d understood. What I have been doing is 4 reps of 40seconds climbing (approx 15 moves) with 5 mins between sets.

Still don’t get why each rest between reps would not be longer, with harder moves on the reps.

Alasdair- cheers, I’ll heed that, especially since my elbows make Michael Owen look like Iron Man :thumbsup:

I wonder if it's just the pure practicality of the session length and boredom of doing such long rests?  Might be slightly less optimal but makes it a more manageable session length? And as you say, the slight cumulative fatigue works a bit of your lactic tolerance too?

I think Alex refers to this in his pdf. btw, I used to do a fair amount of sport climbing especially onsighting, but that was a long time ago and that fitness came from just climbing. So my thoughts here are more theory than practice.

My understanding is that after 45s anaerobic respiration starts to wane and you depend increasingly (and after 120s totally) on aerobic energy systems ie the krebs cycle. (obviously this is concurrent with anaerobic respiration briefly providing power at a faster rate when needed. Aerobic energy production only stops when you are dead) So the aerobic system provides both energy for work and the molecules that will allow the the anaerobic system to resume. So if your aerobic capacity is mediocre, after pulling really hard for 90s+, you are not going to be able to recover.

I am no expert at training by any means but it really worked for me

Each 30 moves would take 40 seconds ish

The first 5 sets would really be quite easy i guess,  then the next 5 would be a building level of feeling Less recovered between each set, next 5 i would be having to try a lot harder ,feeling a level of difficulty to keep hands closed on the rungs and the last 5 everything is going wrong, core failing a bit ,powered down, wooden forearms ,elbows out etc

Always found it funny that my footwork got  so much slopier as the fatigue in my forearms grew , which i blame on core failing

I thought i was working on power endurance as the rests were so short but i am probably wrong, certainly was brilliant when needing to power through sport cruxes  when pumped

^^that is what i would suggest.

Sounds like a very effective way to build a pump Devonshire; I am glad it worked for you. I don't see how it can be anaerobic capacity because the rests are short; they would need to be fairly long, to deal with the lactate produced and reboot the anaerobic system. To me it sounds like you were digging deep into aerobic systems and boosting your capacity to work with lactate levels. Very important, but not anaerobic.

Post by: Stu Littlefair on January 23, 2022, 10:36:42 pm
Perhaps I’m over egging the climb time; but a 15 move problem will take at least a minute for me on a board, and I usually do nearer 20 moves. My rest is definitely of the order of climb time though, perhaps ~30s or so longer. I’m certainly not resting 3x the climbing time. Maybe twice the climb time.

Plenty of other sports recommend sessions more along the lines of what Mrjonathanjr is suggesting, 45s all-out efforts with 4-5 minutes rest to allow full recovery of the glycolitic system. That's what I do in my peak phase though (anpow).

What I do in the base phase (ancap) is more like what cyclists do with hill sprints, where the intensity is lower and the duration longer. You’re not looking to max out the glycolitic system with each rep here, and that’s why the rest is shorter: partial recovery each rep with the aim of draining the glycolitic tank each set. Then ~5 mins rest to allow nearly full recovery and off we go again.

My understanding is that after 45s anaerobic respiration starts to wane and you depend increasingly (and after 120s totally) on aerobic energy systems ie the krebs cycle.

This depends massively on the intensity of the exercise.

Post by: Stu Littlefair on January 23, 2022, 10:56:04 pm
Note also that the standard advice is a 1:2 climb:rest ratio for ancap, so perhaps my initial advice was just bollocks. Certainly what I do is closer to 1:2 than 1:1.

BTW: if you want to read about how the cyclists do this, this blog post is a pretty good summary.

https://www.trainingpeaks.com/blog/how-to-target-the-best-power-and-adaptation-using-optimized-intervals/

Our ancap is the same as their “Functional Reserve Capacity  (FRC)” training. Notice how they advise two different interval sessions for this training, like the ancap/anpow split I describe above.

I'm currently doing a block of strength and ancap. 2 max board sessions, 2 ancap sessions and one aerocap for maintenance.

My ancap sessions are either long boulders (12-15 moves) as Stu mentions or the 'Boulder Triples' session from Crimpd which has you doing 3 laps of 6-8 moves at flash grade with 1 min rest between, followed by 3 mins rest. 6 sets overall.

Completely agree with previous mentions that anything like what Devonshire describes isn't ancap but rather aeropow. Very useful (sounds like a board version of foot-on campus) but definitely more what you would do for ~4 weeks to peak for a trip or project after a longer base training phase. Personally though I prefer a mix of training aeropow on actual circuits and some FoC because it's a) more fun and b) means you maintain good form and technique when really pumped. People often say something like 'but I can go harder if I am not focusing on technique', which I think is the wrong way to look at it seeing as the effort you can sustain whilst maintaining technique is the actual limit you can sustain in reality so you may as well train these two together.

Hope this is useful.

Post by: mrjonathanr on January 24, 2022, 06:25:52 pm
Thanks Mischa, that is helpful. 2 hard boulders and 2 hard a cap sessions weekly? That sounds brutal. A max of 3 hard sessions per week for me with an easy endurance session. That’s working round family, job and middle aged recovery. My recent training so far has been:

1) long boulders ~15 moves/45s duration. x4 reps per set. 2 mins rest between reps, 5 mins rest between sets.

2) short boulders ~6-8 moves:
2a) 6 sets of 3, 30s rest between reps and 5 mins rest between sets.
2b) 3 sets of 6, 1min rest between reps, 5 mins rest between sets

So that seems similar to what others are doing too. The idea is to do 16 weeks then 8 weeks of power based training ie reducing rests so working into lactate and pump. Started after Xmas. Naively I would think the best way to stimulate the glycolysis system is stress it fully, allow sufficient recovery, rinse and repeat. However, most training methodologies don't leave sufficient recovery between reps. Or is that the point?

That training peaks article talks about the best dose-response not matching the performance times exactly. So is it the standard intervals people are already using, or would something better be achievable?

Another question. The cycling methods are based around Functional Power Threshold. This is a measure of average top output over 45-60 mins (albeit measured in a 20 minute burst). This has nothing to with the timings of most boulders or sport routes, so what is the climbing equivalent measure? Seems like the FRC training is based on a very different baseline output to climbing. Any thoughts Stu? Thanks.

2b) 3 sets of 6, 1min rest between reps, 5 mins rest between sets

Sounds about right to me. I wouldn't do more than 2x ancap sessions a week; I can't recover enough to do more. Probably could when I was 20, but then I could do a lot of things when I was 20 that I can't now.

Naively I would think the best way to stimulate the glycolysis system is stress it fully, allow sufficient recovery, rinse and repeat. However, most training methodologies don't leave sufficient recovery between reps. Or is that the point?

Stressing the system as hard as possible isn't necessarily the best way of training it, otherwise (for example) we'd just do aeropow and not aerocap/arc! I think most exercises aim to go to (near) failure but not necessarily per-rep. If you went to failure each rep you'd need long rests, but not so if you aim to approach failure each set.

Another question. The cycling methods are based around Functional Power Threshold. This is a measure of average top output over 45-60 mins (albeit measured in a 20 minute burst). This has nothing to with the timings of most boulders or sport routes, so what is the climbing equivalent measure?

[edit: what follows is totally OTT geekery and is just me musing for fun. If you just want to know what to do for ancap training I strongly advise ignoring it]

The climbing equivalent of FTP would be our equivalent of critical power, which is Dave Giles' critical force. It's not exactly the same thing, but fundamentally, they're both attempts to measure the maximum amount of effort that can be sustained long term, and primarily depend on aerobic ability.

Where I think there is a lot of scope to improve climbing training is that at the moment, most workouts seem based on a % of max strength (for the fingerboard) or "standard" durations for intervals (i.e your 45s ancap intervals).

But an aerobic workout should have an intensity based on your critical force, not your max strength, and some % of critical force/FTP is not a sensible way to calculate the intensity/duration of an ancap workout.

The approach some cycling coaches take is to try and construct a "power-duration" curve. The duration managed at a given power output should closely follow a standard curve, predicted by the critical force/power model. However, when you measure real people you find that there are durations/intensities where they underperform. The basic idea is to target these areas in training.

In a climbing context measuring a power-duration curve would involve something like doing 7:3 repeaters to failure with a range of added weights. The duration you manage at each particular added weight is recorded and compared the expectation from a critical force model. Areas where you do badly are emphasised in training.

This makes a lot of sense to me, but I haven't come up with a way of gathering the data that is easy enough to make it worthwhile. But imagine for a second you had someone who wanted to spend a whole week measuring time to failure when dead hanging, and they came up with the following results:

Weight added   |  Duration Managed | Expected Duration
               10 kg | 2:20                         | 2:10
               15 kg | 1:00                         | 1:25
               20 kg | 1:05                         | 1:05
               30 kg | 0:50                         | 0:43
               40 kg | 0:30                         | 0:32

This climber "underperforms" in efforts just over 1 minute, but does OK at 45s efforts. Arguably, they'd be better off doing their ancap on longer circuits that take 1:00-1:20 rather than the "standard" 15 move circuits.

Slight pedantry but FTP is an hour duration. There are shortcut tests to predict this (i.e. 20mins or a ramp test) which are less hassle if you don't quite pitch it right (or that's what I understand it as anyhow).

Stu - Are you referring to 4DP or if not do you have a link for the power duration curve? I remember getting shouted down a bit when I tried to suggest aiming for a % of CF wasn't practical (or measurable on anything but a rung) for climbing!  :tumble:

Apologies for this slight deviation from topic but hopefully will turn out helpful - I'm always wondering what the different training types actually do for your climbing. I read all the literature etc but I find it hard to translate lactate production and ATP glycosis etc into actual performance.

Is the following about right?

ARCing - builds forearm structures that enable longer climbing without pump
Aerocap - improves your ability to climb without pump i.e. raises the level you can climb to before getting pumped. Also good for improving ability to recover from pump at rests and overall training capacity / tolerance and session recovery.

Ancap - improves your ability to climb near your limit without getting powered out

Aeropow - improves your ability to tolerate pump i.e. climb hard with pump for longer.
Anpow - improves your ability to carry out near maximal moves in a row without powering out?

Post by: mrjonathanr on January 24, 2022, 08:21:53 pm
Thanks Stu. Geekery is good! I am interested in what people do practically to improve, but also to understand more, especially since what I have understood leaves questions in relation to what methods would be best.

I think you have hit the nail on the head with data. I expect in a few years, a few more Olympic cycles, the body of data will be  sufficiently extensive to narrow down what works best and how to personalise it. Probably Lattice's pension plan tbh. however, 20 was a long time ago for me, so now I just want to use my time efficiently. 

It will take a while to digest your point; Lord knows it took long enough to grasp the krebs cycle/glycolytic cylestuff!

edit - Paul, I read (I don't cycle) that it is 45m-60m depending on degree of training but that 20mins at 95% of FTP was a standard proxy to get it. In any case, no hard sport climb takes that long (unless you like knee bars..).
Title: Re: Training different energy systems
Post by: Paul B on January 24, 2022, 08:27:25 pm
It's 60 minutes (see below) and I think you're mixed up; you can output a higher power for less time. Thus,  you reduce your 20 minute power output by 5% to predict your (lower) FTP that you can sustain for 3x as long.

Sounds broadly right to me Rocksteady, although I understood AnCap as effectively lifting both intensity and sustaining near maximal moves, with AnPower being able to access it fully and rapidly.

To respond to this:

I think most exercises aim to go to (near) failure but not necessarily per-rep. If you went to failure each rep you'd need long rests, but not so if you aim to approach failure each set.

I appreciate that exhaustion is not usually the best way to train as it typically requires very long recovery periods, rather I question if intervals with inadequate recovery train the system as fully as they could. I think it's obvious there is a lot going on, just grossly simplified at the level I can grasp it. it really depends on what the rate limiting molecules are and they might be far from obvious.

in that sense, aeropow and aerccap processes might actually be training some very different things, despite looking like they only really vary in intensity. t's really easy to just assume with little knowledge.

No i think we mean the same thing, apologies if I am coming across as muddled. Training Peaks suggested that less trained vs more trained athletes might cycle for 45 vs 60 mins, but 95% of the average power output in a 20 minute burst was a standard way to calculate it. Thanks for clarifying. Any thoughts on how that might look in a climbing context?
Title: Re: Training different energy systems
Post by: Paul B on January 24, 2022, 09:02:52 pm
I think I made most of my points on the Tindeq thread; it's all very interesting but currently there isn't really a way of someone being informed that they're operating in the correct range (as soon as you're off a rung with a strain gauge built in) and when that's the case then it's just a perceived effort affair and for that I don't think you can beat the Barrows PDFs or even the Lattice workouts for descriptions of what you're aiming at. Even if you could scale it from a measured test on the rung, stepping away from that  and onto a circuit board you're just back to trying to remember how that feels. If you then consider all of the factors that influence how something feels (fatigue, caffeine etc.) then I personally doubt how effective that might be. The best quote of my last cycling holiday was "I think my power meter has gone out of calibration" on the last ride of a week which included 10km of ascent (nothing to do with the totally battered legs then  :tumble:).

Again if you jump back to cycling you can buy a trainer for not that many FAs that keeps you within 5% or less of the power your workout requires of you. Speed up and it'll back off. Slow down and it'll up the resistance (there's a grim spiral at the end of a ramp test where you fail so you slow a bit and the trainer reacts so you slow some more until it feels like you're wading through treacle). That's a much harder thing to develop for climbing.

I think as it's massively interesting (and I'm very guilty of this in all sport so please don't take this as criticism) it's easy to get sucked into trying to get everything perfect where in reality it's probably not all that important compared to consistency over a sustained period of time.

Yes, consistency is the key, 100%. (Speaking as someone who is consistently very inconsistent through injury). I do like to understand things though, and I suspect a lot of what passes for climbing training is likely to be very inefficient, so keen to get a better grip on what is productive. Your wattage machine put me in mind of a climbing treadmill, but as was pointed out upthread, uniformity (eg foot on campusing) misses a lot of what is essential for climbing well. Thanks for sharing your thoughts.

My recent training so far has been:

1) long boulders ~15 moves/45s duration. x4 reps per set. 2 mins rest between reps, 5 mins rest between sets.

But an aerobic workout should have an intensity based on your critical force, not your max strength, and some % of critical force/FTP is not a sensible way to calculate the intensity/duration of an ancap workout.

The approach some cycling coaches take is to try and construct a "power-duration" curve. The duration managed at a given power output should closely follow a standard curve, predicted by the critical force/power model. However, when you measure real people you find that there are durations/intensities where they underperform. The basic idea is to target these areas in training.

In a climbing context measuring a power-duration curve would involve something like doing 7:3 repeaters to failure with a range of added weights. The duration you manage at each particular added weight is recorded and compared the expectation from a critical force model. Areas where you do badly are emphasised in training.

This makes a lot of sense to me, but I haven't come up with a way of gathering the data that is easy enough to make it worthwhile. But imagine for a second you had someone who wanted to spend a whole week measuring time to failure when dead hanging, and they came up with the following results:

Weight added   |  Duration Managed | Expected Duration
               10 kg | 2:20                         | 2:10
               15 kg | 1:00                         | 1:25
               20 kg | 1:05                         | 1:05
               30 kg | 0:50                         | 0:43
               40 kg | 0:30                         | 0:32

This climber "underperforms" in efforts just over 1 minute, but does OK at 45s efforts. Arguably, they'd be better off doing their ancap on longer circuits that take 1:00-1:20 rather than the "standard" 15 move circuits.

Funnily enough Stu it was a very vague version of this fingerboard based testing you described that got me training ancap in the first place this winter.

In Siurana in October I kept falling off projects without any pump but just feeling like I didn't have enough beans to pull through a specific move. I could do these moves reliably off the draw but they felt hard and needed precise technique. Most people I was climbing with reckoned it was fitness related because I could do the moves but it seemed bizaare because I wasn't pumped at all - in fact I'd been onsighting really well all year and felt like I could hang around on ok holds for ages.

Anyway fast forward to back home in November and I did some messing around trying to figure out where the weak link was. I found out by using the whole % of max hang idea that I could reps for ages at 60% but burnt out much quicker than expected at 70% and 80%.

I also realised I was often in the position where I could hold onto small holds quite easily but struggled to move from them.

So I found it really useful to test like that, even though it wasn't very precise in the grand scheme of things.

With all this in mind I decided to focus the plan on the 4 day training week I mentioned before with a mixed focus on power and Ancap.

The maintenance aero session is interval style on the 30 board so I defined a 22 move 7a/b circuit for laps and started with 1:2 work to rest ratio. Currently reduced this to 1:1.5 and will keep nudging it down over the next few weeks.
 
The final observations were that I had fairly poor bicep strength so included 2 sessions of offset pulls to help with lock strength and hypertrophy. Actually really surprised by how fast these improved and managed to add around 2.5kg per week the last mesocycle.

@mrjonathanr in general this did feel like a lot of high intensity sessions, but on the other hand I'm being very careful about the volume and doing no other finger training - so no fingerboard etc. I'm also splitting the loading between a few different types of board (homeboard: very fingery, kilterboard: very powerful, spray wall: good mix and some bigger holds) and this really seems to help facilitate the volume. Last week I did 3 sessions on the home board due to necessity and definitely felt a lot more fatigue in the fingers!

Apologies for the essay but I thought it might be a useful addition to the discussion to have an example of how a (very rudimentary) form of testing can be interpreted and applied.

Nice anecdote! I guess it's an example for Paul about how more advanced testing might be useful. Although, to make Paul's rebuttal for him:

1) What you describe above is a pretty classic sign of an underpowered anaerobic system, also called "trad climber's syndrome".
2) If you hadn't been training ancap at all, it was likely a-priori to be a weak spot.

So, maybe you didn't need the testing after all  ;)

I think for lots of people you don't need testing that much to know where your weaknesses lie.. but I do think for some it can be useful. For example if you want to work out whether someone is poor at a certain style/format of route (whether that's endurance, or hard moves, or short PE, or dropping cruxes despite not being pumped and doing the crux ok off the rope)  because of a physiological weakness or because they're bad at that executing on that style (e.g. not relaxing enough, not being able to turn it on enough, struggling to turn on-off in succession, climbing sloppy etc..). You can get a good idea of this from testing on an edge with  strain gauge in a way that might be tricky to work out otherwise (especially if, for example, you're a coach and have limited time with a client to assess their climbing)

Exactly. My point is that you don't need 4DP to predict whether I'm a sprinter or better at dancing on the pedals going uphill. Anyone care to take a guess (36yr old male; 5ft 6; 57kg)? By observation I think you/a coach could easily point to the weak link in someone's energy systems (via qualitative assessment).

See my reply above. I know two climbers who are not super on enduro style. For both I wasn't sure if they were poor at relaxing and climbing that style or genuinely unfit. On a CF test climber A came out as a low CF, climber B had a surprisingly good CF... so climber B needs to learn to climb that style whereas climber A genuinely needs to get fitter. For strength this is often obvious (e.g. if you can 1-arm the lattice edge and climb 7A you clearly have an issue with climbing not strength) but for fitness I think it can be harder to tell just from watching

Yeah, agreed, but then you still need benchmarks for where someone "should" be at on the lattice board or a certain foot-on-campus set up to evaluate whether they have good/bad critical force, and picking apart why someone did well/bad on a certain protocol isn't always trivial... so doing it on a rung and getting an actual estimate in kgs, % of weight and % of max seems like a nice way to do it to me... [though I speak as someone with access to the lattice testing setup if I want it, obviously others may find other methods much easier from a practical POV]

Now I agree in theory but in practicality I was so much in doubt that I could be right about the issue that it was great to have a test confirm it. I'd spent too long misassociating strength with power and aeropow with ancap and only recently cleaned up these definitions - this actually caused a two year plateau whilst I trained the right things at the wrong intensity and got absolutely nowhere.

This was no doubt influenced by many people in my social circle who also had the wrong understanding constantly telling me how I clearly just needed to improve aero endurance because I was evidently strong enough due to being decent on an edge. I also had a tendency to open crimp everything because this was my strongest grip type but obviously was pretty shit for doing powerful moves on steep terrain, something else I wish someone had told me a few years ago (thanks to Ned's book that I finally learnt what I was doing wrong there). My ability to pull on small crimps (10mm>) improved by a ridiculous degree in the space of maybe 4 weeks after I started consciously using a proper crimp grip on the board and whilst climbing. I had to ease into this because in the beginning it felt like my fingers would explode (the main reason I never used it in the first place) but after the adaptation phase there was an exponential progression and I went from barely being able to hang a full crimp with two hands to being able to bodyweight one arm on the BM2K middle rung for a few seconds. I was absolutely blown away by this and am still amazed nobody ever pointed it out to me in ten years of climbing.

The point of all this being that I think checking in on standardized tests can have a really positive effect on learning just by pointing out obvious weaknesses in a way that can't easily be ignored or misinterpreted so for me it's been incredibly valuable. It's not that I lay any specific value to the methodology but rather that as Barrows pointed out, considering these aspects in a very simple format allowed me to be sure of what I needed to work on and not convince myself that I needed more technique/aero/pointless dieting or whatever other random shit the anxious mind cooks up. I've the kind of mind that has a lot of intrinsic psyche but also feel much more comfortable doing long-form sessions as these feel like 'hard work' so it's been a challenge to reel this in and honor the short/intense session volume. 

I'm really curious how next season on rock will feel to be honest!

I agree with this ^^  also, you could get an inconclusive result and be even more confused than had you not bothered!  I've dived into AnCap this year (mainly based on never really having done any focussed training on it).  Might try Stu's test at some point and see how I fair.  I take it that, given I don't have access to any data to compare against, you just do a best fit curve and see where the peaks and troughs are?

If you want to do the tests, I'm happy to analyse the data and send you a brief summary. The easiest way to do this test is probably to devote a full day to it. Warm up well and then do the following:

1) Find your maximum two-arm hang weight on the edge you use. Rest 10+ mins.
2) Do 7:3 repeaters to failure at 50%, 60%, 70% and 80% of your max weight*. Rest 20+ mins between these efforts.
3) Send me the times from each hang and your max weight (incl bodyweight).

*don't forget bodyweight! So if you weigh 70kg and you can add 20kg, your max weight is 90kg. A hang at 70% of 90kg is 63kg, so you'd have to remove 7kg for this set.

From those four hangs I can estimate your critical force and see if any of the efforts above are under predicted by the CF model.

Couldn’t agree more! Very pseudo sports science sounding stuff when what I want is to just get out there and get stuck in. Very difficult for me to do that this year however because of time constraints, hence going over to the dark side and looking properly at training. Figured if that was all I was going to do, I might as well do it well.


I'd spent too long misassociating strength with power and aeropow with ancap and only recently cleaned up these definitions - this actually caused a two year plateau whilst I trained the right things at the wrong intensity and got absolutely nowhere.

Me too; I found it all very confusing. I read Alex’s pdf. Understood it okay. Put it down and realised I didn’t really understand it all. So the only way I would understand it was if I took the time to grasp (at a simple level) the science it’s based on. And I spent a large part of Christmas reading and rereading articles about how we generate energy till it made a bit more sense.

Also I don’t like being unable to judge if something I am reading is good or bad and without some scientific understanding that simply isn’t possible.

Those blog links on the first post are excellent for this. Once you get that 3 energy systems are continually in play, interact with each other and have very specific parameters for providing energy the rest ( and irritating terms like aeropow) make perfect sense; they are a statement of the obvious. So props to Alex for publishing that in the first place, especially as a good understanding of energy systems is only really from the last couple of decades.

And I want to avoid falling off :)

If you care:
NSFW  :
I think it's fairly straightforward to grasp if you look at cycling and if you read the below interchanging CF or even just thinking of a grade it should be fairly clear.

Borrowing from Trainerroad:
Quote
Functional Threshold Power (FTP) is — quite simply — a measure of fitness.

FTP represents the power (measured in watts) that you could theoretically maintain for about an hour, and it's the single metric we use to scale each of your workouts in our shared quest to keep your fitness growing.

With regards to what's taking place within your body and the muscles themselves, riding at your FTP pushes you right up to that limit where pushing any harder will drastically limit the duration of your ride.

But as long as you stay just below that acidic tipping point where your muscles light up and uncomfortably tolerable minutes become barely tolerable seconds, your muscles are in balance with the workload - for about an hour, anyway.

Imagine being able to take a measure (this being your FTP) and applying % reductions/increases to accurately determine which energy system you're training. The curves Stu speak of are a little more complex but ultimately they're just suggesting that the % determined based on a single FTP measure don't accurately reflect the physiology of everyone i.e. those who might naturally tend towards being good in a strength setting vs. those that might be best in an endurance setting.

Now consider that in cycling (unlike climbing) you can measure your power output (in Watts) when on a bike (be it a static bike at home or the one you're riding). That measurement removes any climatic effects (the impact of a headwind for instance) and any other factors that might make you feel you're trying harder/less hard than your workout might required (i.e. being tired, caffeine etc.). Thus, it's better than other indicators such as perceived effort or heart rate.

Take it another step and you can buy devices for not that much cash that you can literally select a workout plan (Lattice stylee but free) and as long as you show up and sit on the damn thing, you can't fail to perform within 5% or so of the workout's target (ERG mode). Before starting you do your test (or tests depending on how you've approached it) and the whole thing will scale automatically. If you re-test mid season, again, everything will automatically scale to keep your workouts correct. The slightly more expensive devices also have the ability to tell you if your pedaling technique is shit.

This has also been looked at in a normalised form and there's a famous table (https://www.saris.com/Uploads/Powertap/2018/7/watts-4.png) basically telling you the W/kg you need to output to be at a given standard.

For climbing, you can measure CF and as Stu suggests you can get some kind of a curve (although I'd imagine for the majority of people this will tell you something that's blindingly obvious) but in my opinion due to the technique aspect of climbing and the inability to measure (and ensure) a given output, CF is limited in offering 'snapshots' of your various energy systems and its application becomes a bit niche (useful for coaches and the ultra-committed in its current form). I think there's a lot of 'perfect' getting in the way of 'good enough' on FB groups on this subject. However, that's just my opinion.

I also can't personally visualise something with a sufficient technique element such as a circuit board, being able to measure force output. However, I've never struggled to find someone near a circuit board to tell me my technique is a bit shit so at least that's covered.

I'm guessing that testing would be increasing percentages of max (also 8s?) for time?

Training 8:1 seems like and unreasonable acid bath or the intensity would have to be super low?

Have you trained in these parameters or just musing upon observations?

Critical force is the same as functional threshold power (FTP) that Paul described above, just different terminology. Basically the idea is it's the highest level of force production you can sustain for a long period of time (where long is usually around an hour).

In the literature to date climbing at a given intensity is typically modelled by doing 7:3 repeaters at some percentage of your max. So say you weigh 70 kg and your max 7s hang is +30 kg, for 100 kg total load. Then if you could only just sustain a total load of 40 kg (or bw - 30 kg) for an hour then this would be your critical force.

In practice you'd usually test your max, then at decreasing intensities (e.g. 80%, 70%, 60%, 50% of max) and fit a curve to infer your theoretical critical force because fingerboarding for 15mins+ is awful.

The testing protocol Stu described here is pretty sensible https://ukbouldering.com/board/index.php/topic,31719.msg653878.html#msg653878 In an ideal world you'd be completely rested before going on to the next set so rests should be long. If you can be bothered it would even make sense to split the testing over a couple of days (e.g. max, 80% and 50% on day 1 then 60% and 70% on day 2).

At a guess, a work:rest ratio of 8:1, unless someone can convince me that 7:3 is a better predictor of performance on sections of sustained hard climbing. 🤷🏼‍♂️

I thought about this overnight because I didn't want to give a rushed response. There's a lot to unpack here! I've split my post into two parts....

Part 1

Firstly, no-one is saying performance at 7:3 repeaters is a predictor of performance. We (I) are claiming they can be used to stress the energy systems in a way that reveals useful facts. Critical force/power tests rely on exhausting the energy systems at different intensities. I'm not aware of any evidence that the work/rest ratio of intermittent efforts matters much; though there's very little study (only https://pubmed.ncbi.nlm.nih.gov/24492634/ ?)

To be sure I put myself through a CF test with 8:1 work:rest ratio and compared to results I get with 7:3 repeaters. Once you correct for the duty cycle (the online calculators and lattice don't) I get statistically consistent answers for CF from both. Only one test subject, but backs up the statement above.

I don't doubt you're right that 7:3 repeaters replicate the work:rest ratio in climbing poorly, but for these tests I don't see that it matters.

Maybe you have a stronger point when it comes to whether 7:3 repeaters should actually be used in training, but even there I'm not sure it matters. After all, fartlek runs don't replicate a 10 000m race very well at all, but I don't think anyone would deny they are a useful training method?

Part 2

I find I have a lot of sympathy with Paul's suggestion that these discussions have a "missing the wood for the trees" effect on people trying to learn about training. I love these threads and find them super interesting, but as an example, a discussion of the ideal work:rest ratio for endurance training on fingerboards could lead to someone missing the main point which is:

Do most of your endurance training by climbing

This will get the work:rest ratio right automatically, plus you'll be working on your pacing, your technique and the mental aspect of handling the pump. Much better

In fact, it could be distilled even further for the vast majority of people to "do endurance training, by climbing, consistently".

Fair enough, thanks for taking a lot of time to consider this! And even doing a pilot study!

One of the reasons I am sceptical, is that when I did an experiment with 7:3 s repeaters on me and my better half (n=2), I discovered that 3s rest is basically complete recovery for her (she has absurd levels of endurance in the forearm flexors, never seen the like in anyone else)

If you don't have a circuit board then a great way to get around this issue is to find a route that's about the right level but with the inconvenient rest or whatever and just use a hold from another route instead - or choose to use the good hold with less fingers etc.

I usually just choose a route a bit on the easy side, skip the rests and force myself to climb quickly through easier bits.

Of course indoors, I think climbing walls should be obliged to put up a few sustained route at every grade. Wall operators around where I live clearly thinks otherwise, which is why I do not patronise them.

Mass-specific cost of transport was negatively correlated with climbing velocity. Increased route difficulty was associated with slower climbing velocities and thus higher costs, but there was no statistically significant effect of route difficulty on energy expenditure independent of velocity.

I love threads like these - as a very time poor climbing dad I am always looking for the most efficient ways to train even if I sometimes struggle to adopt them.

As motivation: can anyone who has adopted energy systems training over multiple seasons explain how it helped progression? Mischa gave a great example of a sort of 'magic bullet' approach, but how has this worked for people over a number of years? Did you get a boost to your onsight/redpoint grade immediately and then each year building on the past efforts, or did it take a bit of time to work out how to make it work for you? Did it rely on having a clear peaking period where you were able to climb loads or can you make it work as a weekend warrior?

As an N=1 example, as a result of testing on myself I decided that I could entirely ditch anaerobic training, as it was well developed. Eventually (and unsurprisingly) it came back into balance with my aerobic ability (as determined by testing), so I put the ancap back in. Like Mischa, I probably didn't need the testing to know this, but it helped me be sure I wasn't making a mistake.

Case studies can never show if something worked or not, but I did go on an on sighting holiday to Greece with Barrows in the physical shape of my life. I was consistently burning Alex off at the Foundry before we went. Once out there, Alex onsighted multiple 8b's and flashed 8b+. I climbed very badly and didn't onsight anything harder than 8a.

If only there was some underlying moral that could be extracted from this story.

I love threads like these - as a very time poor climbing dad I am always looking for the most efficient ways to train even if I sometimes struggle to adopt them.

My last year in Sheffield was the last time I managed to devote sufficient time to follow something well that was energy systems based. Working at a (fantastic) wall massively helped with this (use of the facilities at quiet times) especially when Barrows and Stu were kicking around for me to pester when I didn't understand what I was doing. I got myself in pretty damn good shape and had a good trip abroad even if the route I was hoping for was totally out of condition (baking). The next season that followed I had a great year getting loads done that I thought would take me several years. This may or may not be as a result of the training/frothing at being so close to my favourite crag.

I think if you're very time poor then you might struggle to commit sufficient time. Watching people that choose to train this way, especially those following a commercial plan, it's often apparent that the sheer volume of training has increased markedly.

First thing I'd say is that magic bullets are a rare thing, so don't go into any kind of training expecting one.

Anecdotally, my answer depends on what you call "energy systems training", since anything where you get pumped kind of counts, and it's a spectrum from totally unplanned and unstructured to highly regimented, rather than a discrete thing.

I did some kind of PE work at the wall on circuits from back when I started going climbing (6th form) because that's what people seemed to do to get good for routes. No stopwatch or anything though and no "plan" in terms of periodisation or anything. So in that sense I've done it forever and gone steadily through the grades - though obviously rather faster as an 18 yr old newbie than a 30-something guy with a job who's been at it for years and is chronically injured.

Through uni it was a question of gradually learning more, refining and adding structure. I started traving around the wall for 30min to ARC at the end of the session in maybe my first year at uni based on some Gresh articles on planet fear. Then added more structure to circuits sessions; then realised I shouldn't be just getting pumped all the time 2x per week so started to play a bit more with some kind of periodisation/focus etc.. Though that also happened naturally with seasonal focus (more bouldering in the winter). During the course of uni I went from 7c max RP to 8b, then went climbing for a year and did an 8c (6 week siege).

The next year (2012/13) I got lots of info from Tom, started doing An Cap (which was new to me, whereas strength/PE/ARC was all what I already did). I also started structuring and planning my training a notch more, mapping out periods of time between trips and what I would focus on in more detail. That year I made huge gains, did a few 8cs in ok time and did my first 8c+, then wrote that pdf thinking I had it fuckin' sussed.

2013-2017 I improved at a slower pace, but was probably getting steadily better still. I realised I didn't have it as sussed as I thought and that a lot of the early gains were just from trying that approach for the first time in combination with having just had a year off to climb full time. (I've taken an extended period out to climb on 2 occasions - in both instances when I came back and started training again I had 6-12 months where I saw big gains.) Over this period I probably refined what works for me quite a bit but no major changes in approach/philosophy.

Since 2017 I don't really feel like I've improved significantly. If there is improvement it's very slow! I partly blame this on having a job, being more stressed with other "life" stuff etc. Also I guess I'm now just at the stage where you're looking to eek out a 1% gain and not just to jump a level. I take a similar approach to training as before but have to modify a lot around injury and the fact that my body can't do what it could 5-10 years ago because I'm broken and old. I can't do high volume, I can't do pull ups, can't use crimps etc... but I'm surprised how much you can work around these issues. Now it's more like cycling in and out of form and trying to time it right for trips or dry periods!

Did it rely on having a clear peaking period where you were able to climb loads or can you make it work as a weekend warrior?
I think it works most neatly with trips but it's fine with a block where your preferred crag might be in season (just harder to guess timing), and you could apply the principles broadly without even trying to peak that much too.

I think this approach can be done with limited time - some people seem to manage - but perhaps not if you also value down time! It's a lot harder to fit in than just getting strong, and may depend on what "limited time" means to you too! Works with a full time job but might be hard with full time job and kids? At the least you'll need a decent set of ways to train at home.

Post by: petejh on January 27, 2022, 06:10:09 pm
My experiences of training and periodising in a very structured way have been mixed. I tried it for the first time to try to climb my first 8b and it worked a treat - I did a 16 week block over one winter/spring of nothing except indoor training following a plan, and hit a peak and did the Oak in around 10 visits with it feeling easy on the day.

I thought I'd do the same the next year and do Mecca as my first 8b+, grade chasing mode fully on. Like the first time, I sacrificed a winter/early spring of loads of other climbing possibilities and invested 16 weeks into a block of training, thinking I'd feel in great shape when I exited the other side of it. But it never happened, and it ended up turning into a terrible couple of years climbing-wise which I look back on and feel were wasted and that the effort I'd invested wasn't worth the reward of getting to hang out at the tor 2-3 times a week working what was in the big picture a 2-star route, in sub-par connies for 1 out of 3 visits. After a second winter of training and then coming out and failing again, I lost motivation with it all. That was all purely my choice of course - I could have planned the training to peak for a trip to somewhere nice instead!

Mecca held some allure for its PE style and history as it does for many other climbers but in hindsight it was a poor choice. I should have stayed closer to home to make the process more bearable, or lowered the grade aspiration and gone on holiday and used the fitness somewhere brilliant.   

That second experience put me off sacrificing time to training and I haven't tried training in long blocks since then. I think I went too far the other way and have coasted along way below my potential best for the last 4-5 years. One thing that focussing on training defo taught me was my weaknesses - typical strong fingers and decent power but shit aerobic fitness sums it up. So whenever I let myself get lazy it's fairly easy and quick to improve my level by training my aerobic weakness for a few weeks. Without those wasted months indoors I might not have developed as keen an awareness.

This thread's like an alcoholics thread.

^^that is what i would suggest.

I thought i was working on power endurance as the rests were so short but i am probably wrong, certainly was brilliant when needing to power through sport cruxes  when pumped

Sounds like a very effective way to build a pump Devonshire; I am glad it worked for you. I don't see how it can be anaerobic capacity because the rests are short; they would need to be fairly long, to deal with the lactate produced and reboot the anaerobic system. To me it sounds like you were digging deep into aerobic systems and boosting your capacity to work with lactate levels. Very important, but not anaerobic.

I'm being super lazy here mrJR, but went off to the boulder tonight, thinking about this thread.

My thoughts, and answer to your post here, echoes Pete's post.

I think the mistake people make - if I can put it that way, is that it's assumed that the energy system you're reliant on at the point of failure, is what you need to train and develop to perform better.

The principle of working your base line aerobic system, is that you can rely on this far more, before having to dip into anaerobic systems.

Thinking about your first post, the words that stood out for me were "when gripped".

I've found that, on good, slightly harder trad routes, having better aerobic capacity allowed me to feel far less stressed/tense, and I could maintain better breathing too. In short, I felt under less pressure.

As an experiment tonight, I started with x 4 single circuits of 16 moves, with quite short rest in between. Working like this, it's surprising how well you can recover between reps without achieving much appreciable training effect on your aerobic system.

After a slightly longer rest, I then did two sets of 2 x 16 moves - double length reps - with slightly longer rest between.
I'm not very fit at the moment, and it shows. However, this anaerobic capacity isn't something that would normally be the deciding factor on harder trad.
Four x single reps to finish.

One of my go to sessions involved traversing at Rubicon (maybe 6b+) between poor rests, recovering enough to do a 7 move problem (~6C) up/down before traversing back to a poor rest. I found it really targeted my capacity for recovery between slightly harder sections.

I also found that it helped me judge how well I was recovering.

Decided after 10 days in Amsterdam with 4 good indoor bouldering sessions, maybe it was time for a re-test of max hangs plus some of the CF test.

Max hangs have gone up a little to 26.9kg so my total has gone up to 105kg from 101kg (1kg extra added & 3kg extra BW since last test, 1kg less using strict HC vs chisel).

Just did my 50% repeaters to failure, but kind of *failed* the protocol instead of muscle failure - I dialled in 25 reps to my timer and ran out of reps!  After a mad dash to reset (so maybe 8 secs rest) I pushed out another 3 reps. I suspect 28 would have been my failure point without the extra rest, 27 worst case. I'll put it down as 27 for now.

Update: 60%: 18 reps. Brutal.

Busy resting up now and will do the next test later. I'll finish off tomorrow I think...

Hi Dave, thanks for your reply. I do understand the primacy of the aerobic system and your point about it creating the threshold for the glycolytic system kicking in, no argument there. Obviously, you have a lot of direct experience, so your contribution is very welcome. My point is that not fading when there are a lot of moves which feel difficult is supported by the glycolytic system, which needs to be trained over a longer period than pure aerobic capacity. I want both; just anaerobic is the trickier to train, hence the thread.
Title: Re: Training different energy systems
Post by: DAVETHOMAS90 on February 06, 2022, 11:49:32 pm
The slightly longer - i.e. double circuits of 15-30 moves seem to hit it quite well. It can be pretty hard/stressful.
However, although we're talking about different energy systems, they aren't independent, as I think a lot of people assume, and oxygen is required for ATP production during more intense efforts as well. Our ability to work purely anaerobically is really short.

The key is how far/well supported we can be by the aerobic, before having to dip into the anaerobic.

What tends to happen, is that due to lower than ideal aerobic capacity, we're dipping into the anaerobic battery far more/sooner than we want. Trad routes have to be pretty darned hard before we're faced with sequences that are hard enough to require a full on anaerobic tussle.*

In other words, when we're failing anaerobically, it's more often than not because the contribution from the aerobic system isn't as good as it could be.

*I can't think of one ;)

Great article here:

https://www.trainheroic.com/blog/energy-systems-what-every-coach-really-needs-to-know/

What I was describing above, with the system I was using in sessions at Rubicon, reflects what this author is describing as higher intensity training of the oxidative process.

I was forcing myself to recover in a stressful situation (a poor shake) and I felt I could sense my body actually working hard to process lactate and oxygen - enough to be able to do the next 10 moves up/down more anaerobically. Recovering between traverses and up/down in poor shake out positions was pretty intense, but seemed to work.

The circuits I was doing the other night (32 moves) had less scope for recovery on the concrete, and keeping rests slightly shorter had a similar but less intense effect.

I think it's a case of designing the balance between high intensity work and recovery.

Interesting to think about ..
Title: Re: Training different energy systems
Post by: mrjonathanr on February 07, 2022, 06:39:58 pm
Thanks for that Dave, good summary. If you want a more in-depth look at those systems, the links in my first posts may interest you.

You talk about training your aerobic system at Rubicon. Sounds like a great routine, may have to try that later in the spring. Yes, I completely agree, energy production  effectively sits on the aerobic system, its effectiveness underpins everything. Poor aerobic capacity means poor anaerobic capacity after the first blast because it’s needed for recovery (conversion of lactate> back to pyruvate & NAD+) so the glycolytic system can recover and go again.

Quote from:  Dave’s link
Further, the more you train your glycolytic system, the better you’re able to buffer these {hydrogen} ions and the faster you can recover between sets of moderate to high intensity training.

. Recovering from it actually requires work from all three energy systems. Specifically, glycolytic training develops not only the operation of each individual system, but also the capability to transition efficiently between them. The primary methods to train your glycolytic system are through repeated high effort activities with less than full recovery between efforts.

That, in a nutshell, is why I want to train my anaerobic capacity
ie to cope with bouts of moves I find hard, recover and keep going. Recovery of the glycolytic system is highly dependent on the aerobic system but a) takes longer to train and b) I am confident I know how to train this effectively already (though always open to ideas/advice).

A last thought. Short of one move wonders like The Ace, when we think of being strong it’s invariably linking several hard moves together. And that’s powered anaerobically, hence my interest  :)
Title: Re: Training different energy systems
Post by: DAVETHOMAS90 on February 07, 2022, 07:08:01 pm
I think you're looking at them too independently  ;)

It's not what you're lacking anaerobically that's letting you down.

In other words, the split between anaerobic/without oxygen to aerobic/with oxygen isn't how it works.
What I was training at Rubicon, was the buffering effectively.

In the context of your OP, there's the question of bouts of moves you "find hard" - and what you mean by that, and why.

No, that’s overall middle aged sluggishness!  :lol:

Seriously though, I don’t think I am looking at them too independently Dave, very aware that function is overlapping but components can be usefully trained independently in stints. FWIW my goal is to be fit in June/July/August and just embrace the improbability of getting out much earlier in the year, so training in a more considered fashion for a change.

 I do think effective training doesn’t just replicate the final goal however, at least not in the early stages of the year. So from Easter, increasingly fitness oriented, from May more replicating the patterns of routes. We’ll have to get out  ;)

My end goal is getting on the sharp end of some difficult (for me) trad and knowing there's something in reserve when I'm gripped..   


I don't think that working on what you're calling your anaerobic capacity, in that scenario is what's going to help you best.

I think of it as being a bit like a limited amount of fill-in battery capacity in a hybrid car. Unfortunately, on it's own, it's a really small reserve, and I understand what you're saying about "therefore I want to have more of it available when I need it". However, we're using all energy systems all the time, and on anything remotely stressful, we're dipping into what we refer to as our anaerobic reserves to fill in - ie anaerobic glycolysis

Keeping more of it available for when you need it is more about using less of it until you get there, than having more of it, when you do.

Working more on aerobic glycolysis is where I think you can get the most benefit.

Sorry, I was going to give you a call ;)

Yes, I've seen one of those -  the video from the Khan accademy.

Circuits of ~30 moves, where the climbing is hard enough to be working "anaerobically", with shorter rests in between is what I've been doing - so that it places greater demands on recovery, and being able to "go again" when still pumped, is how I'd describe it.

I've found that shorter circuits won't put sufficient demands on recovery.

What I was trying to emphasise was the demands on recovery. I think "anaerobic capacity" is a misleading term.
Our capacity to keep working when pumped, isn't analogous to having a bigger (anaerobic) battery.

The topping up of "battery fuel" in an F1 car relies on an oxidative process - in the burning of fuel - and it's the topping up process that we're training - so that the car can go again on the next lap.

Interesting we both used very similar analogies just now.
I think the description of what I was doing at Rubicon may give a different sense of what I meant by "recovery".

In other words, when interval training, it's not the "going again" part that the word interval refers to (and where gains are made), but the recovery phase.

FWIW MrJR - and I know you'll deny/disagree with this, I put you into the category of those people I know who are naturally far stronger than they think.

That can also lead to being more injury prone - being still able to pull damned hard when otherwise out of condition.

I definitely felt I'd not eaten enough cakes tonight, but was a bit too trashed from the FBoard yesterday.. and too much sitting around.

Where I was coming from:

"Lactate is always being produced, but when the aerobic energy system is functioning at a high level relative to the anaerobic demands, lactate is quickly oxidised back to pyruvate with can then be used to fuel further anaerobic metabolism.

This is where it can get a little confusing, but to keep it simple let's just say that the moderate levels of energy produced by the anaerobic lactic system can be supported by the aerobic energy system. An athlete who doesn’t have a well developed aerobic system will not be able to maximise the energy production power of the anaerobic lactic system, and they will not be able to recover between rounds of lactic intervals as quickly as those athletes who do have high levels of aerobic fitness."

Good to think about further  ;)

I love threads like these - as a very time poor climbing dad I am always looking for the most efficient ways to train even if I sometimes struggle to adopt them.

As motivation: can anyone who has adopted energy systems training over multiple seasons explain how it helped progression? Mischa gave a great example of a sort of 'magic bullet' approach, but how has this worked for people over a number of years? Did you get a boost to your onsight/redpoint grade immediately and then each year building on the past efforts, or did it take a bit of time to work out how to make it work for you? Did it rely on having a clear peaking period where you were able to climb loads or can you make it work as a weekend warrior?

I think the only reason there is a magic bullet for me is because I totally misindentified my weaknesses and trained the opposite for a two year period meaning I was superbly aerobically developed but far weaker muscularly/anaerobically. Generally these differences will be more subtle. I ended up in the bizarre situation that I felt I could hang around in a static position and shake out on most holds for absolutely ages, but couldn't do the moves from those holds. I'd also developed a weird habit of trying to shake out after every hard move which meant I climbed slowly. I eventually dealt with this by simply forcing myself to climb faster which then ultimately exposed the fact that I couldn't do the moves even if I arrived at them feeling really fresh.

I was also very strong in an open crimp which helped with resting on smaller holds but much much weaker in a half/full crimp which meant I could often hang onto holds easily but moving off them felt much harder.

All in all a very weird place to be in and I look forward to it being somewhat resolved.

Off topic but something else I did this winter was put the scale away and stop worrying about how much I weigh. Bizarrely this resulted in the first noticeable shift in body composition in years. I suspect I weigh more though. Presumably from all the strength training? It's nice not bothering about it though ;D

Cycling has totally changed my perception of nutrition but I had to learn the hard way, under fuelling and having a grim time getting home (I'd also managed to knock my network off on my mobile so my attempt to call a lift failed). I wonder how many climbers really damage their progress by not fuelling sufficiently/correctly? Looking back at my own climbing (especially big days on long routes) I've definitely got this wrong.

I've had a few big days out where I've undercooked it and had to climb the last 5-6 pitches of a route whilst totally weak/cold/starving... Very grim. And then the walk off!

Didn't want to turn this into a nutrition thread but it's a good point that ancap/power sessions go a lot better in the company of ample carbs.

I've had a couple of bad experiences running too, one involving me running home on a Friday night after work having barely fuelled  all day feeling totally burst about 5 km into the 20 or so and having to find a corner shop and grab a bottle of Lucozade and a packet of chocolate chip cookies, and demolishing them  before i felt well enough to carry on running. I always carry emergency food when running now, anything 10km or more.

I've got quite a well adapted fat system and can go a long way on limited food. However, one thing I read earlier this year maybe helped explain one thing...

I didn't know glycogen couldn't be "shuttled". As far as my limited understanding, once it's gone form a muscle it needs replenished but this can't be supplied from other muscles.

So, doing 10-14km of hilly work I would do fine with no added food/energy drinks etc. But whenever going further, my poor wee weak hip flexors must have been fully out of fuel and really struggling to keep up from burning fat alone, hence the weakness and subsequent IT pain. (I noticed that any run where my hip flexors felt ok, I didn't get IT pain, and it always went in that order, so put it down to a lack of hip flexor endurance.

In the RoS I ate a shedload and, despite being 8km and 1000m more than I'd done before, hips and knees were fine.

This is also very relevant for climbing, as your wee forearms are limited in what they can store.

I always found it very hard to fuel for really long routes. Up to the 6-9 hour mark I am usually fine, at which point my muscle glycogen tends to run out and I am a useless dead weight on the team. (I very much doubt I am under-fueling on a day-to-day basis.) Carbo-loading is often impractical in the mountains as who knows what day the weather will be good enough? I used to do long routes with a mate who did a lot of cross country skiing (the winter season up north is about 6 months) and he did a lot better with the same amount of snacking on route.

What we sometimes forget is that the main energy system used in climbing is aerobic metabolism in the legs. (Shown here https://pubmed.ncbi.nlm.nih.gov/17602238/ even if the authors themselves did not seem to understand what their experiments  really indicate). I think we forget as this is energy system is never challenged on a normal day of climbing, except possibly for climbers so unfit that the approach to Céüse is close to the lactic threshold. (In which case they are almost out of stored glycogen by the time they are at the base of the crag.) For long days with approaches and lots of climbing, climbers who have better developed fat combustion for easy aerobic work are just going to last a lot longer. While my mate was doing hours of laps on the ski track for hours on end I was messing around on short indoor boulders. No big mystery why he was lasting a lot longer.

Not sure if I'm missing some tongue in cheeky here - but no, it'll be because he's got better fat adaptation than JWI so could sustain better with less dietary glycogen replenishment.

@Jwi I've found that I can resolve the issue by consistently eating a mix of macros throughout the day but it just has to be a fair bit more than seems expectable. I don't do well with sweets though, better things that have a blend of carbs and fat in that case.

If you want to do the tests, I'm happy to analyse the data and send you a brief summary. The easiest way to do this test is probably to devote a full day to it. Warm up well and then do the following:


1) Find your maximum two-arm hang weight on the edge you use. Rest 10+ mins.
105kg BW 80kg
2) Do 7:3 repeaters to failure at 50%, 60%, 70% and 80% of your max weight*. Rest 20+ mins between these efforts.
3) Send me the times from each hang and your max weight (incl bodyweight).
50%: 280 (inc rest time, so 196 TuT)
60%: 180 (126s TuT)
70%: 140 (98s TuT)
80%: 90/100  (I did 9 reps, but my wrist wasn't too happy - I suspect I could have pushed 10 but was getting pretty powered out) 63 TuT.

Leg fitness, strength and (to a lesser extent) flexibility are hugely underrated by climbers. I guess because we develop them as a byproduct of what we do in our daily lives as much as our climbing and unless we’re into other leg-heavy sports or pastimes we never deliberately train them.

I didn’t realise they were attributes I even had until I didn’t have them any more and everything felt very hard. An absolute bastard to build back up again too.

So, this week I took Stu up on the offer of doing some Critical Force testing, to see if it could shed any light on what's going on with my current level of energy systems.

After my ambiguous lattice assessment ( I broke the system) I was actually unsure as to where I was. I figured from my background (plenty trad, onsight sport trips, winter) and what the assessment seemed to point to, that my aerobic fitness would be ok, and that I should focus this winter mainly on AnCap (short endurance / base work), strength and general conditioning.

I've been doing that now for 10-12 weeks, (with focussed AnCap only since Christmas). I had planned a long block of 12-14 weeks of AnCap, as I hear it's got longer adaptation times.

Anyway, long story short, having now done the crit force test it seems like my Anaerobic Capacity is actually quite high* and my aerobic base endurance is pretty low. Initially this was surprising, as I just generally assumed my aerobic endurance would be ok; but reflecting back on the last trip to Margalef, I was strong on crux sections but struggled on longer, more sustained efforts (i.e. Magic Festival). Also thinking back to the last few years in general, I've probably neglected doing much base aerobic work and only really ever done 4 weeks of "top up" prior to trips etc. My summer trad climbing has been too limited to really make any steady gains.

I was initially a bit displeased with the slightly ambiguous lattice result, but now having done the crit force test *I think* that:

My initial "max moves" was constrained by poor aerobic conditioning, but was still not far below what was expected due to high anaerobic capacity. Then, because my 75% effort was relatively easy for me, it didn't drain the anaerobic tank meaning my subsequent 2 laps could both still be completed.

My takeaway (and Stu's recommendation) form all this is that I need to shift over pronto to some base aerobic work for 4-6 weeks, followed by some quality power endurance work closer to when I'm aiming to "peak".

I've got 3-4 weeks in europe at the end of March where I'm really just aiming for mileage, skill practice and onsighting, but is there a good way of "getting fit on the routes"? Throw some back to back laps at the end of the day?




*Stu did caveat that the data on that bit is not the strongest, but it also ties in somewhat with my inability to drain the anaerobic tank in the lattice 75% tests.

Stu, are you using that CF should be 41% of the max 7s hang with a standard deviation of 6.2% as in the first of the two papers of Giles and co authors? N=12 seems small
Title: Re: Training different energy systems
Post by: Stu Littlefair on February 15, 2022, 07:24:15 am
From the larger second paper (around 120 participants), and my own less formal sample of friends and people I’ve tested.

The larger paper uses a different methodology (an all out test) but the results are similar, if not totally identical.

I’ve seen CF range from mid 20s for boulderers to mid 50s for very fit sport climbers.

Very possible this has been discussed already, but anyone have any thoughts on Dave Masons ultra low intensity, ultra high volume finger stuff for increasing work capacity? I’ve just listened to his recent Careless Talk podcast, and it sounds appealing as something truly supplemental with no impact on other training. Sounds totally unappealing in terms of time commitment. However, gaining strength to a certainly level is easy for me as it’s my most accessible training modality, but endurance isn’t. Going climbing is a luxury and my session stamina is so low. Would be nice to be making more of a limited resource, maybe by using other downtime.

For those who haven’t heard, it involves a spring based hinge pinch block thing which Dave uses low resistance high volume. He says someone like Barrows would get no benefit but for him as a through and through boulderer there could be significant gains.

Anyway, I don’t know I could hit the hours he suggests you need, but also hard to commit to something without much evidence beyond one person.

Post by: abarro81 on April 22, 2024, 04:30:03 pm
I've actually done a reasonable amount of this kind of thing in the past, with various different exercises - powerball, doing bicep curls and wrist curls with dumbbells only (or 1kg weights), holding a pinch block or pick-up edge with not much weight, EMS machines, and even juggling! Usually swapping exercises when I get bored but racking up blocks of time in front of the TV or similar.

It's really hard for me to know what does/doesn't work, but my feeling is that it's quite a lot better than nothing but not as good as "real" ARCing. It seemed to keep my fitness up when I couldn't do normal fitness for a summer due to my finger. Of course maybe that would have happened anyway. It's a lot easier than normal training to to in front of the TV, in the car (I don't do it when driving personally), or in a hotel room with work. I've also found it useful when injured - sometimes doing more ARC seems dangerous on my joints but smashing out some powerball and weights can be quite safe (though the weights can be aggro on elbows or nerve issues). Doesn't need chalk so easier to do in the living room too.

It's also nicer on skin. Doing anything for an hour or more seems like it can get tweaky so I think swapping exercises makes sense. I'm currently doing some with Pinch Thing and Powerball, and am going to keep doing it this summer at a highish volume along with normal Aero Cap to try to build some more fitness. We'll see if it works... Or more likely I won't really be able to tell like most things 😂
Title: Re: Training different energy systems
Post by: abarro81 on April 22, 2024, 04:34:08 pm
Worth noting, I don't see this being hugely useful for building work capacity (day fitness) for bouldering personally - I find my work capacity for easy climbing and for hard climbing seem quite distinct and the only way to build the latter is doing big days of hard climbing... But I do think it will build base endurance, so if that is a limiting factor for someone's work capacity on harder stuff maybe they'll have a different experience. My and Dave's limiting factors are probably rarely the same thing!
Title: Re: Training different energy systems
Post by: monkoffunk on April 22, 2024, 05:39:35 pm
Oh interesting that you are doing it! I guess the assumption was that with tonnes of other endurance stuff, the percentage gain from it would be low compared to him. I guess that might be true but it still be worthwhile. And yes it’s always a challenge to work out exactly what has the impact.

I suppose for me with big percentage gains to be had, not just fine tuning, it could be different again. Intuitively I’d agree with that final point, it seems too be too good to be true that there would be some way for me to squeeze in more top end boulders into a day without training that specially. Or just improving tactics even! Although Dave did talking about being able to link powerful moves late in a session when that would previously have been impossible. Maybe worth experimenting with adding it at low impact times, as seems reasonably low risk, and I don’t have time for proper ARC!

Gains will definitely be low for me, but all gains are at the moment  :lol:
