Great stuff coach. That USA gymnastics paper is a great one. I was crunching some numbers on the crossfit games winners and there is an obvious need for a certain level of strength to have the engine to perform, but beyond a certain point additional strength either blunts metabolic conditioning or takes away from time that could be devoted to skill work. I suspect this strength-needs curve is shifted up for gymnasts but a similar scenario is seen.
I've been thinking about this in terms of evolutionary biology also in that endurance adaptations come and go quick and easy but strength, especially beyond a certain point is very slow and tough to bring about.
"Survival will be neither to the strongest of the species, nor to the most intelligent, but to those most adaptable to change."
