The method of using EMG fatigue threshold and JASA to evaluate the muscle fatigue of the middle-distance athletes in specific sports has been established , which is feasible , applicable and reliable . 2 .

研究结论：1.建立了使用肌电疲劳阈和幅频联合分析来评价中长跑运动员专项运动中肌肉疲劳度的模式，具有较好的可行性、适用性和可靠性。

EMG frequency domain characteristics of the changes in MPF and MF are basically the same , but MPF is relatively more stable for establishing the EMG fatigue threshold and JASA .

肌电频域指标MPF和MF的变化特征基本一致，但MPF相对更稳定，较适合用来确定肌电疲劳阈与进行幅频联合分析。

Use the time domain indexes to establish EMG fatigue threshold , use JASA ( Joint Analysis of EMG Speetrum and Amplitud ) to observe the degree of muscle fatigue , and compared with the individual lactate threshold .

以时域指标建立肌电疲劳阈，采用幅频联合分析来观察肌肉的疲劳程度，并与个体乳酸阈进行比较。

The EMG parameters such as MVE % , MF and MPF , and especially their changes during the performance were still able in indicating muscle fatigue during repetitive work , which was demonstrated further by the JASA method .

肌电指标（如MVE%，MF，MPF及其斜率）在操作过程中的变化可以反映动态劳动的肌肉疲劳，JASA分析证实了这一点。
