摘　　要：为探讨山地车运动员腹背肌群的耐力特征,研究以江苏省女子山地车运动员为研究对象,对运动员的躯干腹背肌群进行等速耐力测试,同时采集腹背各肌肉的表面肌电信号,分析运动员耐力测试过程中疲劳指数、耐力比以及各肌肉的均方根振幅和积分肌电的变化情况。研究结果显示等速耐力测试和表面肌电信号均可反映运动员的疲劳情况,且结果基本一致。根据测试结果,可有针对性地制定腹背肌的训练计划。In order to explore the endurance characteristics of trunk muscles of mountain bike athletes, the isokinetic endurance test of back was taken in Jiangsu female mountain bike athletes. At the same time, the surface EMG of abdominal muscles and low back muscles was recorded. The fatigue index, endurance ratio, RMS and IEMG of each muscles were analyzed. The results showed that the isokinetic endurance test and sEMG can reflect the fatigue of athletes, and the results of the two methods showed no obvious difference. The training program of torso muscles targeted at the weakness can be worked out according to the result.
