摘要：

背景：本体感觉的降低将导致身体不能对失衡的状况迅速做出反应，从而导致运动损伤的发生。
目的：观察股四头肌和腘绳肌肌肉疲劳状态对膝关节本体感觉的影响。
方法：14名受试者参加测试，在肌肉疲劳前先对受试者膝关节关节角度位置误差进行测试，然后在90 (°)/s速度下重复进行等速向心运动直至肌肉疲劳，在肌肉疲劳即刻、疲劳后每隔10 min分别进行关节位置觉误差的测试。
结果与结论：肌肉疲劳前关节位置觉误差为(2.85±1.46)°，肌肉疲劳后误差升高为(6.32±2.54)°，肌肉疲劳后40 min，关节位置觉误差恢复到疲劳前水平。因此，肌肉疲劳可造成膝关节本体感觉的降低，使关节受伤的危险性增高。

Abstract:

BACKGROUND: The decline of proprioception delays reaction to imbalance status, and results in sports injury.
OBJECTIVE: To study the effect of quadriceps femoris and hamstrings fatigue on the knee joint position sense (JPS).
METHODS: A total of 14 volunteers participated in the joint position error test. First the knee joint position error test was measured before muscle fatigue, then the muscle fatigue was caused by isokinetic concentric exercise on the velocity of 90 (°)/s, and JPS error signals were measured immediately after fatigue, and every 10 minutes thereafter for 1hour.
RESULTS AND CONCLUSION: Before muscle fatigue, the accuracy of knee JPS was (2.85±1.46)°. After muscle fatigue, the accuracy increased to (6.32±2.54)°. Knee JPS was recovered to normal level at 40 minutes after muscle fatigue. Therefore, muscle fatigue leads to low knee JPS, which can increase the risk of the knee injury.
