After 8 weeks of training, knee extensor and flexor muscles strength can be improved, but knee extensor muscle torque increase more than flexor muscle.

Objective To study the effect of isokinetic training on knee extensor and flexor with nerve function abnormality caused by partial denervation or hemiplegia.

In this article, the author studies the age and gender characteristics of knee extensor isokinetic muscle strength development of 240 primary pupils aged 7-12.
