Effect of joint velocity and pre-activation on the torque-fascicle length relationship of the vastus lateralis
Tristan Tallio, Antoine Nordez, Lucie Lecarpentier, Sylvain Dorel
This study examines how joint velocity and pre-activation affect the torque-angle and torque-fascicle length relationships in the vastus lateralis during isokinetic knee extensions, finding that velocity alters operating length but not optimal length, and isometric pre-activation reduces torque.
