Isokinetic muscle strength characteristics of the knee, ankle and trunk
Abstract：BACKGROUND:Isokinetic test has been generaly used as an objective indicator for assessing the functional state and sports injury of the muscle system in athletes. OBJECTIVE: To explore the isokinetic muscle strength characteristics of the knee, ankle and trunk in footbal players. METHODS: Cybex-Norm isokinetic testing system was used to test the flexion and extension peak torque, relative peak torque and relative endurance of the isokinetic double knees double ankles and trunk at different angular velocity. RESULTS AND CONCLUSION:There was no significant difference between the muscle strength of the bilateral knees and ankles (< 5%). The extensor peak torque and relative peak torque of the knee were lower, and the flexor peak torque and relative peak torque of the knee were higher, especialy in the left knee, which is not conductive to the effective completion of bal control, kicking and vertical jump. The relative peak torque of the trunk was relatively weak, which is prone to damage during exercise and results lower back pain. Relative endurances of the knee, ankle and trunk are not satisfied, which can be improved greatly.
