Abstract
Muscular fatigue was investigated in m. rectus femoris, m. vastus late ralis and medialis of 15 patients after an anterior cruciate ligament injury. Using a Lido active (isokinetic) dynamometer, combined eccentr ic and concentric contractions were carried out at intermediate contra ctile velocity speeds (150 degrees, 240 degrees/s). In addition, conce ntric contractions were also performed at fast angular velocities (300 degrees, 400 degrees/s). The results indicated that fatigue was signi ficantly greater for the intermediate speeds. Given one angular veloci ty, the average eccentric force decline was more pronounced than the c oncentric one. At all velocities the relative decrease of peak torque (PT) was smaller than for contractional work (CW).
