【摘要】 根据抓举与抓支撑练习在前后方向和垂直方向的动作幅度、速度、力值等实验数据的对比分析,认为抓支撑练习的训练作用主要表现在垂直方向促进撑铃能力上,而在前后方向训练抵抗倾倒力矩以及调节杠铃重心能力方面显得较弱。首次提出利用影像测量数据中足尖和足跟在前后方向的位置曲线围成的区域与"人/杠"重心曲线的关系来量化分析评价撑铃过程中前后方向的稳定状况。更多还原

【Abstract】 According to the comparative analysis of the front and vertical action range.Speed and strength between the snatch and prop practice,this paper claims that the snatch prop practice mainly promotes the prop barbell ability in vertical direction,but is weak in resist tip torque in front and back direction and the ability to adjust barbell center of gravity.It first proposes to use the area that toe and heel in front and back direction curves in the video test and the relation of "person and barbell" center of gravity to analyze the stabilization in front and back direction in the process of prop barbell.更多还原
