Title: L/R difference switches when tired??
Post by: Duma on June 04, 2020, 06:49:02 pm
Sorry for terrible thread title.

So I noticed something really weird (to me) today:
On one armed hangs my R is significantly stronger than my L - over 3kg, but once I'm a bit tired my L is significantly better??
R feels stronger as I warm up, and hangs are easier on R as I reduce assistance. However today, at the end of the session I tried gradually increasing assistance after a couple of goes at max (5-6kg assistance for R, 8-9kg for left), and did five more hangs on each arm at gradually decreasing total load.
Weirdly as soon as I got past below L max (best today was -8.5kg,effect obvious at -9kg) I felt much better on L, around 8s hangs vs 5s on my R. This continued for the next couple of hangs and even at -15kg although I could hold R for 10s it was much harder than L.

Hopefully that makes sense, anyone else noticed something similar?

Doesn’t happen when tired, but it does randomly happen for a session or so before switching back.  :shrug:

Neurological. Maybe you could read a classic French novel to activate right dominance and ponder a few Zen koans if you want to fire up the left?  :-\

😂 Love it JR.
Some more thoughts:
I'm lefthanded;
Am stronger on one arm pull ups on my left;
Have an old wrist injury on my left that is still troublesome on slopers and occasionally during fingerboard stuff;
Am still in final stages of recovery fron golfers in my right elbow;
Have an ongoing (minor) scapular stability issue on my right that may feed into the golfers thing.

Reason: Because it's like that, and that's the way it is.

I'm lefthanded;

But what does that mean? I write with my left hand, so would traditionally be viewed as left-handed. But I climb right-handed, play golf and tennis right-handed, play pool left handed, play the guitar left handed. If I was in a knife fight, I'd be right-handed, if I was using a knife to carve it would be left-handed.

Supposedly the US army had a test that resulted in a 100 point right-to-right scale. Most people were in the range 100/0 to 80/20ish . I tried an abridged version and was 55/45 - not ambidextrous, just ambi-useless (can only use one hand, just random which one it is).

I do everything left handed (or footed) except board sports, I skate and surf regular.

Sounds like potentially your right arm is wired up better from a motor neurone perspective allowing you to recruit more muscle fibres at the same time, but your left arm is fitter, probably from years of ‘preferential use’. 😄

Supposedly, footedness is entirely unrelated to handedness. There is a roughly 90/10 handedness split, and an 80/20 footedness split but they are independent. More left-footers are right-handed than left-handed.

I board goofy but am right handed. However I do a lot of things with my left. Doesn’t matter which side a mouse is on...

Cut with my right hand - write with my right - but am alright with left (I’m sure with practice it would be the same)...

Are you now or have you ever been a trad. climber?

I have noticed something similar. I'm right side dominant (write right handed, kick a ball right footed) and on max. hangs I'm ~2kg stronger. My left is more fatigue resistant - better 'short endurance', some cap or power - than my right.  When trad. climbing I subconsciously favour placing gear with my more dextrous right hand so spend more time hanging on my left arm. I surmise after decades of this my left takes longer to fatigue.

I climb right-handed

What does climbing right-handed mean? I climb with both hands, have I been cheating all these years?  :oops:

Next thing you'll be telling us you use both knees too.
