| Maximal knee extensor isometric peak torque. Timepoint: Pre test and post test values of dependent variables are obtained immediately before, immediately, 48 hours, 120 hours and 14 days after the performance of 2 bouts of eccentric exercise. Method of measurement: newton meter.;Concentric peak torque at 60 and 180 degree per second velocities. Timepoint: Pre test and post test values of dependent variables are obtained immediately before, immediately, 48 hours, 120 hours and 14 days after the performance of 2 bouts of eccentric exercise. Method of measurement: newton meter.;Angle of concentric peak torque at 60 and 180 degree per second velocities. Timepoint: Pre test and post test values of dependent variables are obtained immediately before, immediately, 48 hours, 120 hours and 14 days after the performance of 2 bouts of eccentric exercise. Method of measurement: degree.;Electromyograhical activity of vastus medialis part of Q.C muscle. Timepoint: Pre test and post test values of dependent variables are obtained immediately before, immediately, 48 hours, 120 hours and 14 days after the performance of 2 bouts of eccentric exercise. Method of measurement: microvolt.;Electromyograhical activity of vastus lateralis part of Q.C muscle.
