ABSTRACT
Introduction:
The knee joint is the most complex weight-bearing joint in the human body. An athlete's knee joint is prone to injury in competitive sports; it is one of the most common injuries and, in some sports, severe meniscus and cruciate ligament injuries occur frequently as, for example, in handball and soccer, and can even end the career of an elite athlete.
Objective:
To explore the comparison of knee flexion and extension force injury in different athletes.
Methods:
The characteristics of the flexor and extensor muscle of the knee joint in handball, football and cycling were studied with the isokinetic technique.
Results:
The role of the knee joint in different types of sports played by athletes is obviously different, which leads to the different requirements of the flexor and extensor muscle in the knee joint.
Conclusions:
The key to improving the conditions of superior strength and preventing sports injury is to develop the features of specific strength reasonably. Level of evidence II; Therapeutic studies - investigation of treatment results.
