I’m not sure I agree with his reference to the Russians claims that the myelin sheath strengthens as a result of repetitive exercise. You will certainly get adaptation at any synapse junction in the CNS which will improve reflex control/contribution to the movement.
Furthermore, you’ll have to explain the drop landings in more detail. I don’t see any physiological benefit. Could it be that it is a way to stress the contractile elements eccentrically and bypass the elastic tissue partially?
DB: thanks to the Blickham spring-mass type articles I have added 15m at least to my top end acceleration so that I’m now accelerating up to 60m at least.
Work In Progress 😉
