Why do we pump our arms when we run?
« on: 31/08/2009 17:33:01 »
 
You know the story. It’s late on Friday night and you are trying to run from the police with your arms handcuffed behind your back. We’ve all been there, haven’t we Geezer? Apparently, one of the main reasons police handcuff suspects is because they become more compliant, being able to walk but having trouble running. Why is that, then? And can double arm amputees run as fast as able (or in my case, ample) bodied people?

Come to that, why do some girlies (and effeminate men) run all ‘flappy armed’? A, Variola? A, Karen?

p.s.
Just for purposes of clarification, I mention Variola and Karen as examples of girls, not effeminate men.

p.p.s.
I mention Geezer as a stereotypical caricature of a Scotsman and, as far as I know, is neither a girlie or an effeminate man.

can double ... amputees run as fast as able (or in my case, ample) bodied people?

This double leg amputee runs at Olympic speed ...


http://en.wikipedia.org/wiki/Oscar_Pistorius

His prosthetic legs had previously been outlawed but are currently considered legit to race against able-bodied athletes.

Back to your original question ...
I think thrusting arms out of sync with legs has a stabilizing effect on the torso, which otherwise would be twisted left and right with each stride, making it more difficult and more inefficient to run.

Yes, it's all about keeping balance.

That is amazing !! I have never seen any prosthetics such as those... Those are really snazzy! Way different then any I have seen.

I am glad you said..."some girlies" and not all! LOL..

I agree with the balance thing also!

I am a girlie but never in my life ran with my arms

flailing around.. I was raised in the country with all the

neighbor hood boys.. and on the rare occasions that I ran

it was much like a good runner! No effeminate arms

flailing around! LOL....

Hi Nizzle

Yes, it's all about keeping balance.

I'm sure I read somewhere that this is a common misconception, at least in relation to swinging arms while walking. I had an idea it was an efficiency thing, but I can't remember. If there are any double arm amputees using this site please write and let us know (probably using your nose to type).


Hi RD

I think thrusting arms out of sync with legs has a stabilizing effect on the torso, which otherwise would be twisted left and right with each stride, making it more difficult and more inefficient to run.

Ah, the font of all knowledge, RD. That sounds closer, to me. I reckon it's to do with better returns for energy expended. I'll see if I can dig anything up to support my theory.

That is amazing !! I have never seen any prosthetics such as those... Those are really snazzy!


Come round with an axe and some lengths of iron and I'll see if I can knock you some up.  :)

I am thinking on this why could it not be to build momentum when running to help propel the body in a forward motion when running, helping to shift and distribute weight in a forward motion with less effort cutting through the air instead of just hanging and causing a more sheer wind resistance on the body, slowing down of the bodies movement?

Springy stilts can enable superhuman performance …

So you can see why Oscar’s springy prosthetic legs may be an unfair advantage.
