The duration of muscle activation is indicated by the yellow-highlighted region on the time axes. Time zero is defined as the beginning of the propulsive phase (see ‘<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0173415#sec002" target="_blank">Methods</a>’ section for details).

Peak shortening power occurred when peak muscle force and peak shortening velocity were achieved.</p> 2017-03-10 18:36:50 contractile conditions muscle-tendon unit vivo muscle force peak PL power leg extensor muscles peak power output frog leg extensor muscles power output
