Fig. 3 — The graph shows changes of knee extensor muscle strength: (A) isokinetic torque (60°/sec) and (B) isometric torque in both groups. (A) Isokinetic torques of right knee extensor increased significantly over time during training period in both groups and there were no significant differences between study group and control group. Isokinetic torques of left knee extensor was not significantly different during training period in each group and between groups. (B) Isometric torques of both knee extensors increased significantly over time during training period and there were no significant differences between groups during training period. Asterisk (^*) indicates statistical significance between baseline and 1 month (p<0.05) and double asterisk (^**) indicates statistical significance between baseline and 2 months. ISK, isokinetic; ISM, isometric; Rt, right; Lt, left.
