不同运动速度下膝关节损伤运动员的伸屈膝最佳角度

Best angle for knee-injured athletes to stretch and flex their knees at different movement speeds.

本文通过对45名膝伤运动员在60°/s、180°/s、240°/s三种速度下的等动测试,研究其在上述条件下的最大伸屈膝力量所处的角度(即最佳角度)。

An isokinetic test of 45 knee-injured athletes at a movementdseed of 10 degree/s, 80 degree/s and 240 degree/s seperately was used to study the angle(namely the best angle)for them to develop their maximal strength of the stretch and flexion of knee under the above conditions in this paper.
