need some physics/biodynamics gurus to school us on how earlier/later onset of armswing could effect force production.

It's said that the more forceful and explosive the arm drive, the more forceful and explosive will be the leg drive.



right of course, but i'm interested in the timing of it.. slightly different topic.

"Now Cornell University neurobiologists, studying the adrenal glands of rats, have discovered how chronic stress cranks up the intensity of this adrenaline response. The key to this so-called molecular memory resides in a donut-shaped protein on the surface of cells that secrete adrenaline, the hormone also known as epinephrine."

PED's in drug free sports is cheating, unethical, and weak. Athletes and/or coaches who condone/display this behavior can get lost.

You know, I was thinking, and maybe the arm swing is what breaks my two-footed jumps - if you happen to lower the arms at the same time as the legs are amortizating the plant, then the force generated by the amortization of the bodyweight + the additional pressure created by the arms "pushing you" into the ground could possibly overload the quads and mess up the jump.

Also, if the arms and upperbody aren't moving more vertically and if the timing is bad, the upperbody will go forward and you will jump forward (will not be able to convert from horizontal movement to vertical movement).

I should film my two-footed jumps from the side and compare them to someone else at the same moment in time and see what I find out.
