Title: Benchmarking survey
Post by: slackline on October 10, 2012, 07:37:03 pm
Awkward and time consuming for someone to collate the information from forum posts so I knocked up a quick survey (https://docs.google.com/spreadsheet/viewform?formkey=dGpjTF9lZ3lkekNlRG56QzBkM0YyQXc6MQ) for people to complete and will do some analysis once N >= 30 and report back.

Have filled out as best as i could. Never really tried to hang a really small edge or onsight/redpoint sport (not in the last ten years anyway)

Thanks for setting it up  :great:

Oops, just realised i filled out the max hang bit for one-handed. Have never tried to max out two handed.

Its not essential that every field is complete (bar height, weight and boulder grades), but the more data the better (avoids having to throw instances out due to missing data or having to rely on multiple imputation).

Should probably add (to save me the hassle of having to clean the data) there is no need to enter units, just make sure they're entered as requested (i.e. don't use Imperial).

If there's a field you don't have a value for just leave it blank, no 'na' as that then requires a string to be converted to numeric (which is easy but a pain to have to do, annoyingly Google Forms doesn't have the option to specify a field as numeric, only text.

And I don't believe that someones height and weight are both '10'  :spank:

Height - 186cm
Weight - 75 kg
Fingers - +10KG deadhang on large BM hold.
Can hold second to smallest crimps on a BM (consistently)
Pull ups - weighted c.10KG, no lock off on one arm.

Boulder - 7B+ max, 7A/+ ish in a session
Which BM?  1000 or 2000?

Wow, good work Slackline.
I only have a few data available though.
Title: Re: Benchmarking survey
Post by: slackline on October 10, 2012, 08:33:06 pm
Not a problem, but if you want to hold back on entering data until you can get some of the others that would make it a bit easier.

I guess people can submit data more than once as I intend to remove duplicate entries based on height and weight as I'd be surprised if there are many people with exactly the same metrics for both of these, but it would be easier if people do intend to get more benchmarking done if they could hold back and enter everything at once.

Ok, I've added a "name" field just so I can identify multiple entries (so please use the same name if you're making a second entry!).

Doesn't have to be your real name could use UKB or something completely anonymous if you don't want to be identified.

And entries should be current.

Yep, because there is supposedly a data management team who are meant to take care of that, but they're useless.  Theres a relational database in place, and can I query it using SQL over an ODBC connection?  Can I fuck, the "export" just dumps each of the tables out to ASCII CSV files and I then have to recreate the relationships between the data as needed.  Really what is the point in having a relational database if you can't query it intelligently?  :furious: :rtfm:

You might get more useful responses using beastmaker holds rather than wanting to know how deep the edge people can hang is. I for one don't have a clue what depth any hold is but do know what I can/can't hold on a beastmaker..

Well my reasoning was simply that not everyone has a beastmaker but anyone can take a ruler/tape measure to their fingerboard (or the one at the wall) and find out the depth of the smallest hold they use, thus making it a more generalised survey.

Given there are now 34 survey completers it would be perhaps too onerous a task to reset the questions and ask everyone to do it again.

If this were at work then the Case Report Form (the survey) would have been piloted and undergone a number of revisions, but its not a formal epidemiological study and just a quick survey for a bit of fun, albeit with some formal structure.

Indoor grades are a load of bollocks anyway.

It would be useful if people don't already know some of these could hold back on filling things in and find out over the coming days and then complete the form.  At the moment besides the bouldering grades the most complete field is maximum pull-up reps.

EDIT : I didn't know I was 186cm and 84kg  ;D

Do i have to do some sport climbing too?  ;D
also how do people go about testing how small an edge they can hang? I can hang small edge bm 2000 and the slopey 2 finger pockets but not sure about smaller as ive ever tried it/had a smaller one to try on
and as far as weight stuff I dont really have any acess to any of it
Title: Re: Benchmarking survey
Post by: abarro81 on October 11, 2012, 02:16:38 pm
Hence my suggestion about using BM holds instead of sizes - more people have access to a BM 2000 than will be bothered to find edges and measure them. I'm not even sure where I'd find appropriate edges. I think anyone who was bothered enough to do the survey would do it again after a modification; plus it would allow comparison between grips types, which I had kind of thought was the main useful thing which might come out of it.
Title: Re: Benchmarking survey
Post by: andy_e on October 11, 2012, 02:21:04 pm
But I can hang smaller edges than those on the beastmaker, and I'm sure a lot of people can. Plus I don't have access to a beastmaker.
Title: Re: Benchmarking survey
Post by: Dexter on October 11, 2012, 02:28:06 pm
does this not also depend on the material of the edge and its angle/level of incut?

I still think
more people have access to a BM 2000 than will be bothered to find edges and measure them

1 armed hangs should remove any issues with holds being too big, and anyone who can do multiple 1 armers on the small BM2000 edges and doesn't fill in font 8c and F9b can be excluded as they probably have no legs. There could still be a category for smallest edge for those who know. I just don't think that the current survey is detailed enough to yield any useful results, especially given how many people wont be able to answer the questions.  :sorry:

Go for it then.

I used the "Forms" under Google Docs to design the existing one, I'm sure you can do the same.
Title: Re: Benchmarking survey
Post by: andy_e on October 11, 2012, 02:41:20 pm
The beauty of beastmakers is that the holds are generally all the same size. If one person measured the beastmaker hold, then everyone could use that measurement for the "smallest edge" category. Or perhaps a "smallest hold on the fingerboard that a lot of people have therefore everyone has to have definitely been on at some point in their life unless they chose an alternative product which is likely as there are tens of different models on the market" category.

I think finger strength is such a biggie that it needs to be right. How about using a campus rung? they're more common than BM's, particularly for an international audience. I propose testing 3 grips on the smallest campus rung (incut edge up) - 4 finger open hand, 3 finger open hand, and 4 finger half crimp.
I'd also like to see a test for core strength, but I'm not sure which is best, possible dishes?

 :agree:

Especially when no BM 2000's are even remotely similar in frictional qualities. There's no chance I am going to test myself on mine, maybe next time I'm in the depot I'll do it.

The hang duration question would probably also be more useful for a standard size rung. Eg. how long can you hang a 1cm flat edge?

Different campus boards are incut to different amounts and have different sized 'smallest' rungs.

Perhaps we should view this survey as the pilot and work on it after we have some results?

I was thinking most people would have access to a campus board at a wall, which I've presumed generally to have a degree of standardisation ie: 15 deg?

Maybe, it's a standard core test for other sports, I think that most climbers would find it too easy though with test times being minutes long. But it's the specificity that's the key.

If anyone wants to design a comprehensive study controlling all variables then these are all good ideas and would form the basis of deriving a grant proposal to a funding body (which body that would be I've no idea, would the BMC fund such research?).

Ideally you wouldn't even use BM or campus rungs you want to test everyone on the same device, but as everyone is spreadout across the country/world and there is no money to pay for travel expenses that isn't going to happen (so yes the next best thing is consistent finger board or campus rung, but there will be variation in friction/mounting/conditions).

As it is I've no money to do so and am intending on doing the summaries and analysis in what little spare time I have, so I stuck a few simple and generalisable measurements that most people can assess easily* and enter the data for and I'll do some summaries and simple statistical analysis.

The reason I stuck the survey up in the first place was because people had started posting details in the thread itself and thats a really inefficient way of collecting data as it would mean "someone" who wanted to analyse the data would have to sit down and transcribe all the individual posts into a spreadsheet/database before it can be looked at.  So when I saw that people were starting to post details I quickly knocked up the survey so that people wouldn't be wasting their time posting details in the thread and then nothing would ever get done with it.


I think I'll leave things as they are see how this goes, if it gets a decent response rate (currently upto N = 44 with varying degrees of completeness), then it might be worth running it again.  For now though consider what has been set up as a pilot that will provide useful insights for future surveys.  Its a trade-off between actually getting something vaguely interesting done or just posting what you can do to a forum thread and nothing being done with all the data.





* Really its not that hard to take a tape measure or ruler next time you use the finger board at the wall.

Are the "max hangs" one or two handed?
Title: Re: Benchmarking survey
Post by: slackline on October 11, 2012, 03:13:04 pm
I envisaged Max hangs as being two handed.

Future versions could expand on this and have two handed, left and right with associated sizes for each.
Title: Re: Benchmarking survey
Post by: ghisino on October 11, 2012, 03:39:10 pm
can someone provide an example of how their max weighted 2 hands pullup relates to their max 1 handed weighted/unweighted pullup, and/or 1 armed lat machine?

(i tend to work one-armed taking weight off, rather than two-armed with added weight)




btw the hang is intended as one armed or two armed? if two armed i find it a dubious benchmark past a certain level, as:
1) it becomes a matter of skin/rung compliance more than finger strenght. Too dependent on room temperature and on the edge of the rung (sharp or filed down?)
2) sub-1cm rungs ain't very common

if one-armed i need to make a new entry :)

I'm surprised no one has raised the issue of variation in the style of problem or route ascended (i.e. does it make sense to have your max boulder problem 7A on a slab comparable to a 7A roof).  Far more important than the relatively minor differences in rung size/angle/conditions/etc. of a finger board.

If folk are using a wall/campus board would it be useful to have a basic endurance based test, e.g.:

Perform 1-3-5-5-3-2-1-1 (leading with alternate hands) on small rungs using a crimped grip until failure.

how many reps did you manage?
what was the duration


Perform 1-3-5-5-3-2-1-1 (1 rep) on medium rungs using a open-hand grip until failure.

how many reps did you manage?
what was the duration

Or are pure strength tests alone a suitable way to assess route climbing?

i'd say that it is an implicit and hopefully accepted flaw of any such benchmarking attempt.

but on the other side if you take out the most extreme outliers, i'd expect to see a sort of correlation at least in terms of "minimum required fitness for each grade".
Because of how we use the grading scale, problems or routes that really don't require any special strenght and are purely technical tricks will never get past some grade...probably font font 7A and sport 7c, or even less.

I think several hard "slab" boulder problems are a good example of what i mean.
Eg. "the storm" at stanage.
Of course you need to be quite flexible and have good footwork to do it...but would someone succeed just by flexibility, footwork and technique??? Or does it require some kind of strenght once your left foot is placed?
(i dunno, i couldn't get very far once my left foot was in place- maybe because of poor footwork and flexibility  :))

Hadn't raised it but been thinking about it and people's ability to perform on better on a certain type of problem. So I came up the following dead simple, utterly foolproof, solution  :blink:


Max OS grade
Consistent OS grade (could think-of-a-number required)
Max grade you've climbed a minimum of four* problems/routes
Max grade you've climbed

And maybe:
Consistent one-session grade (implies multiple ascents of said grade but could specify, e.g. six*)

*being numbers plucked out of the air

i found the heel helped but I think crucial for me was reaching a little farther right than the obvious sloper and finding a small seam at the back of the hold that I could curl a crimp into.  Keep both hands on as you rock up then keep stretching a little bit further and further...

- max time on 1,5 cm (bodyweight)
- max time on 1 cm (bodyweight)
- max time on BM one pad monos (middle fingers)
- max time on BM small pockets (front2)
- max number of one armers (on 4,5 cm flat edge)
- max time 90° lock off

I don't know whether and/or how these data could be useful.

All good to consider for the future, although my concern is that once holds are standardised people will then start quoting the relative humudity/amount of time holds have been in direct sunlight/other inane variable that might make a fraction of a difference.

Thats not to say that the proposals aren't useful, more to highlight the high degree of possible variables becomes insanely high (e.g. 90° lock off, on what hold?).

I'm not a fan of dredging data because ultimately if you test enough variables something will come out significant (this can be countered by an often overly conservative Bonferroni correction) and would rather have people suggest the training benchmarks that they think are most important to guide variable selection.

I would tend to agree on the idea of keeping the measurements as simple as possible.

For example, it's much easier for a comparison survey to use:

Can you do a one arm lock off?  (full lock at chin) - yes/no
Can you do a one arm pull-up? (no swinging/kipping) - yes/no

These are simple to measure and accurate to compare. 
Max OS grade
Consistent OS grade (could think-of-a-number required)
Max grade you've climbed a minimum of four* problems/routes
Max grade you've climbed

And maybe:
Consistent one-session grade (implies multiple ascents of said grade but could specify, e.g. six*)

*being numbers plucked out of the air

Would defo agree with this.  It should help to eliminate odd outliers.

Done the survey albeit my contribution is at the old git punter end of the spectrum

For info the smallest edge was that on a BM 1K (guessed at 8mm)and I assumed you want 4 finger hang times, . Also have data on hanging other holds with fewer fingers if you want it.

One suggestion would be that age would be an interesting factor - apologies if is already there and I missed it on the form

Also after checking training diaries realised my 1RM for a pull up is 24kg not the 20 I put - DOH!

No, you didn't miss anything and I realised I should have collected date of birth (more accurate and consistent than asking peoples age as I can derive age based on dob and date the survey is completed).

Also should have collected gender and arm span (to either include separately or derive ape index).

Collating these and all the other suggestions to include in the summary under "What to improve".


For those yet to complete and thinking of doing so....

There's no point simply entering your height and weight along with climbing grade as the aim is to see how training performance relates to climbing performance.  Please enter at least some of the metrics (pull-ups, and edges are pretty straight-forward, if you don't have a finger board use a sturdy door frame).

I don't think that's right.  The interesting part about the BM 2K small bottom outside crimps is the added slope at the end.  They're dead flat for about 1cm, then slope and round out to finish at about 18mm.  (leastways on mine they do)

Don't your results show that an increase in strength due to a large increase in muscle mass (caused by not climbing a lot and going to the gym loads) does not lead to higher climbing grades?  There's a difference there!

I agree;  the crucial thing there i think, is not climbing a lot. Climbing is ultimately a movement based sport. There are moves which you can only overcome with base strength, but I would have thought (and this is practically unprovable) that on the vast majority of moves, the quality of movement is more of a determinant / limiting factor on completion than base strength level. Thus, if you don't climb much, you don't tend to climb as well, though you may be pumping iron for England, or Bulgaria, or where ever you like to pump iron for.

I doubt it since this is purely "observational" and any analyses will reveal only correlations, which do not imply....

Whats more likely if there is an association between bench pressing and climbing performance is that there is a third factor that correlates with these two....the amount of time spent climbing.

Anyway, got some figures sorted nicely last night, here's a sampler...a box-plot (http://en.wikipedia.org/wiki/Box_plot) of pull-up repetitions by outdoor bouldering grade....

(http://i.imgur.com/WlBC4.png)

...which shows that there is trend (no claim as to significance yet) between the maximum number of pull-ups and outdoor bouldering grade (but if you want to do more pull-ups you shouldn't bother bouldering, see the grey "NA" box which represents the pull-ups done by people who didn't enter bouldering grades).

would a scatter plot with correlation co-efficient work better for that and give a more accurate quantifyable level of correlation (maybe needs grade converting into a single number so 6B=1 6B+=2 etc)

would a scatter plot with correlation co-efficient work better for that and give a more accurate quantifyable level of correlation (maybe needs grade converting into a single number so 6B=1 6B+=2 etc)

It could be drawn as a scatter plot, but bouldering grades are an ordinal data type (even with the grade conversion you are proposing, which is how the data is stored anyway, its just the x-axis is labelled with something meaningful) rather than a continuous one and the advantage of a box plot is that it shows the median and inter-quartile range within each category.  If it were drawn as a scatter plot you would have a series of dots in columns above each bouldering grade showing the spread of pull-ups within each category. 

Plotting like this would not facilitate the calculation of any correlation metric which is done independent of plotting any graphs, but would mean that no information is conveyed as to any measure of centrality (i.e. average which in this case is the median) or dispersion (in this case the inter-quartile range shown by the boxes).  I could conceivably calculate the correlation co-efficient and have it as added text to the plot, but I'm not sure that would particularly useful as the intention is to perform multivariate analyses.

Also the original question as proposed by rich d was along the lines of  "how many pull-ups can the 'average' 7b climber do", and these graphs convey that by showing one measure of 'average' and the spread around that measurement within the category (scatter plots would only show the spread but provide no quantification). This is why I opted for box-plots instead of a scatter plot.

Whereas pull-up strength is one thing I don't have to worry about to get from bouldering 6B to 7B.

I then moved to Yorkshire, I couldn't do any pull-ups (parents' house: weak door-frames and no chin-up bar) but I was unemployed and spent a year or two solidly grit bouldering - did lots of f7b+'s and the odd soft 7c.  After that spell, I had a go on a chin-up bar and found I could only manage around 10 pull-ups. By my understanding of science, if I chop off my arms and get down to zero pull-ups, I'll have a bouldering grade of font-infinity!

I'm crap at picking up sarcasm on the net.

I've absolutely no idea how to capture or quantify technique accurately, but figured the distinction between on-sight/red-point sports routes might be one method.  My reasoning being  that technique is of far greater utility to on-sighting and the strength of any relationship between feats of training strength would be weaker when that is the outcome.

Duly noted and will be incorporated into the summary and where to take things next I'm compiling, cheers.

Could be confounded by indoors/outdoors though where the above "technique" is better learnt outdoors, yet many people these days start indoors and tend to develop strength over technique.

The way this is going, it'll soon be demanding more computational time than SETI and the Human Genome Project combined. 

By the way did you ever see the height versus sport grade study that someone on 8a produced.  The analysis method was rather odd, as I recall, the average height for "top" climbers was around 173cm and the average increased as more non-"top" climbers were included.  However, this suggested that the most elite group of climbers would be a tribe of pygmies..... that said, I am sure we all remember the rapid rise in standards that accompanied the cast of Time Bandits visiting Malham.
Title: Re: Benchmarking survey

I guess it depends on how honest people are and how the question is phrased....

When did you start climbing?   <--- Could easily lead to mis-leading results.

v's

How long have you been training/climbing in your current cycle?  <--- Might be more appropriate.
How long have you been training/climbing without a significant break?  <--- Might be more appropriate.


Its a major drawback of these sorts of "epidemiological" surveys, you can't control things*.  Which is why people do experiments where they can control things (viz. everyone hanging on the same hold and timed as discussed above).



* You can't even control how people respond to questions...


...all of which needs 'cleaning' before you have a dataset you can use.  This isn't a problem though, and highlighting these shouldn't discourage or prevent people from completing the survey, the more complete data the better.

Actually I find that my onsighting relies just has heavily on my raw power as my redpointing, probably even more so - when redpointing I can trick my up stuff more by finding sneaky beta whereas on onsights there's more reliance on being overstrong and being able to pull through moves in inefficient ways.

After having written that I gave it more consideration and thought it might be the reverse situation you describe, but then countered myself thinking perhaps technique is just as important when on-sighting as it means you are more efficient in your climbing meaning you don't pump out hanging around placing gear etc.

I don't think there will ever be an easy way to quantify someones technique.

The data set does keep on getting new entries, currently upto 80 entries now, and I'm a bit lazy to keep on reposting it whenever its updated and would rather share it when my analysis is complete (although the survey will remain open and it will be straight-forward to re-run things at a later date).

Well, I've not had masses of time to spend on summarising results, but as I'm away this weekend, busy with work next week, then off to Spain the week after for some bolt clipping I thought I should share what I have done so far.

I've added a section to the Training : The Science (http://ukbouldering.com/wiki/index.php/Training_:_The_Science#UKBenchmarking) page of the wiki that links to the PDF report ukbenchmarking.pdf (http://ukbouldering.com/wiki/images/5/53/Ukbenchmarking.pdf) that I've written.  I did a short literature search and have hopefully summarised some of the papers I found to give some background on similar work that has already been done in this area.  There is then a description of the summaries and the intended analysis (its the analysis that I'm yet to get round to doing).  Lots of pretty graphs are then presented, there's an empty section on the modelling results and a virtually non-existant discussion and future work before the references that are cited are listed.

All analyses were done using R (http://www.r-project.org), the graphs were created with the R package ggplot2 (http://ggplot2.org/) and the PDF was written and prepared in LaTeX (http://www.latex-project.org/).

I would warn against over-interpreting these graphs, they're showing the spread of things at the moment, the planned statistical analysis will then quantify if any of the patterns seen are of any significance.  I've tried to include links to web-pages in the PDF that describe the graphs and statistics that are intended to be used (likely send most people to sleep, but they're there for those who are interested).

I've uploaded all of the graphs I've generated so far to a gallery (http://imgur.com/a/4i9TP#0) and added brief titles and descriptions (hopefully I've got them all right, but if in doubt they are correct in the PDF, labels on imgur or below are wrong if there is any discrepancy).


For simplicity they're embedded below....

For anyone wondering the data on front-levers was so sparse I didn't think it worthwhile graphing.

Yes I could derive correlations for each of these but thats not overly useful in isolation and would give you lots of correlations whereas the intended generalised linear model will allow the derivation of partial pseudo-R2 statistics for each dependent variable and some ROC analysis to determine the sensitivity and specificity of the model (hopefully!).

The survey remains open so if you've not submitted any data yet then feel free to do so, but please bear in mind the point is to include some training metrics as well as your height, weight and bouldering/sports route grades otherwise you won't be providing particularly useful information.  And please do not bother entering units, the questions indicate the units you should enter them in (cm/kg/mm/seconds) you don't need to write them (nor should you enter in other units, e.g. don't put your height in as 1.8 rather enter it as 180 as the former is in metres the later is in the requested centimetres).  Its a bit of fun, nothing too serious, but I can see it being improved on based on suggestions here and taking a little more time to design the survey (I did it in about five minutes after people started posting their training feats and climbing grades to the forum).

I'll try and get round to doing the intended modelling (was planning on doing some whilst on holiday, but my laptop is going away today for repair and may not be back in time).

It could also be due to longevity of problems... you may try that 7C for 5 years and eventually get it, but depending on how often you go to the wall (and how often they re-set) you'll only get so many chances before its gone.....

It may be because 6b+climbers kip 20+ times in a row and still count those as pullups. Everyone counts differently after all, so maybe even those doing only 10 pullups are kipping too  :shrug:

Anyway, well done slackers. It looks like it took a lot more work to do this than i had certainly imagined  :icon_beerchug:

It appears to me there is a small negatiove correlation between heavy weights (bench, dead-lift) and boulder grade. Would really need to be referenced for weight as well I expect to understand it. However 'climbing-type' exercises seem to have a slight positive correlation. Moral: weights are perhaps not all they're cracked up to be. I wonder what Mr Sharratt would say?

Hold size tends to decrease with climbing ability though (i.e. better climbers can hang smaller holds).

Eventually I expect something like size/time to be a more useful way of summarising these though.

 As difficulty is inverse to size of hold I'd call that a positive correlation.

But if you calculated a coefficient of correlation with the data as it is it would be negative.  Its your interpretation that leads you to call this pattern a positive relationship.

I think you're right, to be of any real use the weight lifting performance should be divided by the bodyweight;  without this it is a little meaningless.

Post by: Rocksteady on October 25, 2012, 12:34:46 pm
Slackers this is well interesting.

Looks like I'm one of the outliers as I can do 20+ pull ups on a bar (strict, no kipping) and one-arm pull-ups (with a bit of a kip) each arm but only boulder V4/5 and redpoint F7b. Can bench press 1.5x my bodyweight - doesn't make any difference to climbing as far as I can see. But I get loads of finger injuries and am only just learning to be stronger on small holds. 

My observation from my own experience (and not contradicted by the stats) is that core strength, hip flexibility and finger strength are the main determinants of climbing performance. I almost feel that being quite strong in my upper body when I started climbing was a negative, as I got into lots of bad habits. I think if you can transmit power from your feet through your core to your fingertips you'll climb hard. What I seem to do is pull hard with my arms and push hard with my legs but sag in the middle.

I feel this is a mix of technique, strength and flexibility - I'm trying to sort it out. Been doing more bouldering over the last year and am starting to see improvements.

Perhaps once your fingers are stronger then some of the ancillary strength stuff might make a difference - i.e. if you can do a one-armer on small holds then that must help?

Three things...

1) Patterns can be seen but they may not be significant, that will come from the modelling I plan to do.

2) I intend to release all the data (anonymised) in due course for others to mess around with (as both a fully labelled R data set and ASCII CSV files).

3) Despite 87 responders the numbers in each grade category are small.

nice work slack.graphs and numbers are always interesting

as for weights,i think if you are a serious weakling.weights will benefit to a degree.nothing will ever be as good as technique though.
i went from 13st 4lb to a max of 15st 10lb and benched 140kg,deadlifted 200kg but it doesnt need slackers and his science to tell you i climbed wank.i was a lot stronger/heavier but it doesnt transfer to rock in the slightest.
since ive cut out lots of food and doing lots of biking ive dropped to 14st 7 and the climbing is getting easier everytime i go out.looking forward to a winter of grit climbing and enjoy getting out again.
my hope is some of the strength stays as i get back to a better climbing weight

I used to be like that. At one point I could do 4 or 5 one-armers, but was only climbing about 6c or 6B+. Basically, I had a pull-up bar at home and trained pull ups because it was easiest to access. When I was climbing at my best (several grades harder), I could probably barely manage a single one-armer. Even now that I am climbing relatively infrequently and am weak due to a young family and crap geography, I am climbing harder than when I had super strong arms.

I am proud to be at the bottom of the scale on everything but pullups. Nowhere to go but up (and no need to train pullups for a while).

I found it interesting that - juding the charts subjectively by eye - things like pull-ups, smallness of edge hung etc. appear to correlate more strongly with bouldering than with route performance. Which I guess make sense because a lot of other factors - endurance, tactics etc. - play a bigger role in routes than in bouldering.

That didn't stop some from filling it in!

Nothing stopping you from getting some metrics though, and it would likely be very useful as I suspect you're from the opposite end of the spectrum from the intended point of the survey (i.e. I get the impression you get mileage in on rock rather than training for hours, yet still climb relatively 'ard).

Love the graphs, especially how much they highlight my punterishness on every level.  Great work slackers

Cheers, glad people are liking the graphical summaries, I'll try and get some statistics sorted soon to show what is 'significant'* and what isn't, but new laptop is off being repaired (had intended to take it away to Spain and spend down-time doing work on this, scuppered unless its back by the 2nd Nov.).

As Stubbs mentioned - bench and deadlift are better expressed in proportion to body weight. Not too complicated to work out


Not quite in the benchmarking spirit, but might show trends with which to compare the weights/pulls/grades graphs.....

BMI against grades would be good (has this been done/suggested and I've missed it?)

would be interesting to see hight to grade just to prove that climbing is easier for short people

and where is the "physically attractive" measure?

and everyone knows that routes are easier with an 8b tan - data to confirm this would be most welcome

Not been done or suggested, but I'm not a great fan of BMI as it tends not to work too well for particularly muscley people.  Can add it in though.

Would need to be on a logarithmic scale so that everyone else has a chance against your handsome self lagers.

Waist to hip ratio is my preference, but likely awkward for people to measure consistently.

There might just be enough data to do that (usual approach is to split a data set in half, derive a model in that half and see if the predictions are accurate in the second half to validate the model).

Shirely a height against weight relationship makes perfect sense to climbing (whereas we all know BMI is only used because it's easy, not because it means anything). Try turning it on its head, height over weight squared perhaps?

Oh shit look at that slight negative trend between height and bouldering grade, you've played right into the tallies' hands!

Looks like I'm the gangly outlier on that one! Imagine willackers should be there too though?

I wouldn't worry about it too much, with a larger sample theres bound to be someone with a higher BMI than you who can climb as hard. :P

I should add that if anyone keeps a diary of their training and climbing then they could easily analyse themselves to see what training level equates to what level of performance (although it might be a ballache to have to enter it all into a computer if its kept on paper).

its the one-armers where there is so many missing or zero's its barely worth bothering.


Assumes that respondents are unable to do a one-armer and therefore there's no correlation between grade climbed and the ability to perform this party trick exercise?

Confirms more of what I know. I'm a bit too heavy, don't have a strong enough core or fingers to climb as hard as I'd like. Thank fuck there's no measure of technique or flexibilty. I think slackers deserves an OBE for services to climbing training. I'm going to print off the height vs bouldering grade graph then laminate it and carry it around at all times so that when some short arse starts moaning about my lankiness helping me I can hit them with some science (obviously I'll have to bend down to show it to them)

Yep, missing I've replaced with zero and a graph with essentially flat lines showing zero variation for most grades is pointless and that its got no relationship to grade climbed.

Do you mean in a manner like this - comparing training intensity/volume to performance level across lots of different people  or meaning correlating periods of varying training volume/intensity with performance level?

If the latter, I think it's actually quite a hard thing to do as you not only have to consider (and somehow gauge - hard to do accurately) intensity and volume, but also exactly which energy systems you're working on and how long for, and you have to worry about how to take into account what you've been doing previously. E.g. If you go day-on-day-off for a month and climb really hard it doesn't necessarily mean that you should be following that protocol all the time.

The later because whilst there are indeed the considerations you highlight the data is specific to you, your strength/weaknesses/styles etc. rather than trying to draw conclusions from others who are vastly different to your own physiology/psyche/strengths/weaknesses.  So whilst the things you are suggesting may be hard to quantify its just as hard to do so across many people completing a survey (be it this one or another) and on top of that you have the variation between others to compound things.  By using data on yourself over time you are taking out the variation between individuals.

EDIT : Obviously if many people keep diaries then there is the potential to perform some longitudinal analysis (http://en.wikipedia.org/wiki/Longitudinal_study) using retrospective surveys (or even better prospectively), but such a survey is a long way off, and would require more time than I've got to dedicate to this (unless the BMC wish to fund it :clown: ).

That's for sure with me, I am still a good few cm's shy of the shortest one in my grade category... (assuming I managed to read the graph correctly).
But I'm ahead on the front levers.
Hurrah for front levers.

Updated Report (http://ukbouldering.com/wiki/images/5/53/Ukbenchmarking.pdf)

There have been about another 20 or so people completing the survey so I've re-generated the graphs and recompiled the report.  I'm too lazy to upload all of the individual graphs to Imgur and then embed them here again, so if you want the most recent/complete overview see this PDF*.

Might get round to doing some more of the planned analysis today, but further work may be put on hold as I'm likely to have to reinstall Gentoo on my laptop in the coming week as its having its hard-drive replaced under warranty.

Is there a facility by which to test hardest grade climbed against hardest grade flashed? I'd be interested to find out if there are as many people as me who have flashed a whole number less than they've climbed or if I'm just truly terrible at reading sequences...
Title: Re: Benchmarking survey
Post by: slackline on January 23, 2013, 04:29:26 pm
Yes I can probably find time to generate a scatter plot of that.

I did sit down over xmas and start playing at modelling relationships but the data is actually quite sparse in so much as very few people filled out all fields.  I could test each training variable to see how it predicts route/bouldering performance but I don't think such an approach is useful because for starters the factors influencing performance don't work in isolation and are going to be correlated with each other in some way.  Its also prone to problems associated with multiple testing.  Instead I prefer multivariate approaches, but for each predictor variable you generally need 10-20 observations to detect a resonable size effect.  Thus I'd be looking to have around 200 complete observations and there weren't more than a dozen.

I'm interested as well, for both bouldering and routes. 

My hardest flash is 6 number grades lower than my hardest RP :)  (7c vs .13d)

Good point, I can't provide you with a plot of hardest flash v's hardest worked grade for bouldering as I assume you're interested in (get the impression you boulder more than sports/trad) because I only requested indoor/outdoor bouldering grades.

I did however request the on-sight and red-point grades for routes so can do a plot for those.

Or is it that you'd like to know how your hardest boulder grade stacks up against your hardest onsight of routes?
Title: Re: Benchmarking survey
Post by: andy_e on January 23, 2013, 05:01:42 pm
Yes, I boulder more than sport or trad (just like one is more than zero  ;D )

I'd like to see max flash vs. max workedfor bouldering but the other permutations could be interesting too.

Can't do that for bouldering, only have onsight/redpoint for routes and for bouldering, well see my last post.  ;)

You don't need data for this, I can confidently inform you that if your flash/onsight grade is a number grade below your worked limit you are undoubtedly relatively bad at flashing/onsighting.
Title: Re: Benchmarking survey
Post by: slackline on January 24, 2013, 07:40:51 am

Go for it, the survey is still there.  How you encourage more people to complete the all fields of the form I don't know (I did link to it on Reddit Climbing which got about five more people filling it in).  If someone fills it in again but more complete then please ask them to record the same name as the original so as to facilitate removal of duplicates.

I have thought about a second survey in light of comments made in this thread and including flashed/worked boulder problems is included.

Very interesting report.

I think something that would be interesting and significant to track would be hours climbing/training per week vs grade. I suspect this would have one of the biggest correlations.

I may be reading this box plots wrong but it looks to me like someone on here can bench press 200kg, do 40 pull ups, and climb Fb7C! That's some serious all round strength!

Thanks!  ;D It'd be interesting to know if I'm an anomaly though or if other people are affected by the same tardiness as me.

Slackers, is it easy to set up a new survey just asking those questions I want?

Yes, I used Google Docs, but you could use Survey Monkey or similar, there are lots of options.  The problem is (always) getting enough people to complete the surveys.

I may be reading this box plots wrong but it looks to me like someone on here can bench press 200kg, do 40 pull ups, and climb Fb7C! That's some serious all round strength! 

Well the person who can do 40 pull-ups climbs F7b+ but if they were in the F7c category you can't tell from box-plots that the data points relate to the same observation (unless they were labelled).

Not at present, it appears that when the UKB Wiki was upgraded the file permissions for uploading were reset to allow only png, gif, jpg, jpeg.  The section on the Training : The Science (UKBenchmarking) (http://ukbouldering.com/wiki/index.php/Training_:_The_Science#UKBenchmarking) still links to Imgur where I hosted the  individual  box-plotfiles.

This page (http://ukbouldering.com/wiki/index.php/File:Ukbenchmarking.pdf) suggests that the file should be there, but as you say returns a 404.

@Bubba : Has the location of uploaded files changed between wiki upgrades?


Note also that jwi is doing a benchmarking survey too (http://ukbouldering.com/board/index.php/topic,21734.0.html).
