A) Association between hamstring muscle volume and both sprint performance and mechanical properties. B) Association between adductor muscle volume and both sprint performance and mechanical properties. R: Pearson’s correlation coefficient. V0: theoretical maximal velocity. Pmax: maximal power output. F0: theoretical maximal anteroposterior force. Black circles represent female sprinters. Grey circles represent male sprinters.
