| 摘 要： | 通过对实验组和对照组学生短距离发力的肌电图测试法和等速肌力测试法联合测试,采集到每个人体八个部位的肌电IEMG值和MF值,以及等速肌力的峰力矩和角度,对各通道的肌电数据进行距离分析和Mann-Whitney U检验,对等速肌力测试数据进行T检验,最后对两组IEMG值和MF值分层聚类的Q型聚类分析,发现对照组与实验组身体左右的IEMG差异值存在非常显著的差异;实验组大部分肢体的IEMG值都小于对照组;实验组的IEMG值和MF值都趋于同一类型。

| Abstract: | Utilizing technologies of superficial electromyogram(sEMG) and isokinetic dynamometer,the integrated electromyogram(IEMG) and mean frequency(MF) were measured on eight sites in body with short-range push.Then the data were studied by distance analysis,Mann-Whiteney U test and Q-cluster analysis method.The results indicated that :(1) The IEMG of the left side in body was different from the right side,meanwhile,there was significant difference in the difference between the shadowboxing exercise group and the ... |
