| 摘 要： | 采用高速摄影与等动测试相结合的研究方法,对女子举重运动员抓挺举时的等动肌力特征进行探讨。结果显示,抓举发力阶段,提肘动作发生在伸髋结束时,不同关节等动肌力的比值反映了举重发力动作的先后顺序;抓举与挺举上挺发力阶段的最大相关速度与上肢等动测试的峰力矩,平均功率相关指标有显著性相关,而最大速度与等动测试的峰力矩、平均功率指标无相关性。

| Abstract: | Combining high-speed photography with isokinetic measurement, the author discusses the featrues of isokinetic muscular strength of women weightlifters in snatch and jerk. The results show that in the start phase of snatch ,the lift-up of elbows occurs after the extension of hip joint;the ratios of peak torque between different joints indicate the order of lifting actions;the maximal relative speeds of the start of snatch and the push-up of jerk are significantly correlated with the relative indices of peak torque and average power for isokinetic tests of upper limbs,while the maximal velocity is not correlated with peak torque of isokinetic tests and average power indices. |
