| 摘 要： | 采用芬兰产Mega6000肌电仪和肌电仪器自带的Megawin2.4软件系统,让实验对象在做大腿后部肌群的力量练习手段如直腿后摆拉橡皮条、俯卧屈小腿拉橡皮条、俯卧后摆腿、俯卧跪起和仰卧挺髋力量练习手段的状态下,对实验对象的臀大肌、股二头肌、半腱半膜肌、腓肠肌内侧、阔筋膜张肌、股直肌和胫骨前肌进行肌电测试,并结合高速摄影技术分析肌电特征和肌肉的工作机制。结果表明,各块肌肉在力量练习过程中放电顺序、放电强度、放电时间、肌电积分值都不相同。因此,在力量训练时,应根据动作结构、肌肉收缩方式、收缩速度和力量大小等方面进行训练,使训练手段更能符合专项运动的规律。

| Abstract: | With the adoption of Muscle Tester Mega 6000 and Megawin2.4 software,the test was carried out to measure the EMG of the subject′s gluteus maximus,biceps femoris,semitendinosus and semimembranosus,medial gastrocnemius,tensor fascia lata,rectus femoris and tibialis anterior muscle during strength training.Then,Analysis of EMG characteristics and working mechanism of muscle were made possible by means of high-speed photography.The results show that there are some differences among such parameters as muscle′s discharge order,discharge intensity,discharge time and EMG integral.Therefore,strength training should be conducted according to movement structure,muscle contraction mode,contraction speed and force size,and it is obvious that training methods must meet the special law of movement. |
