团身后空翻三周动作是有加分因素的D级高难动作。该文通过查阅文献,专家座谈,结合拍摄到的我国优秀运动员完成的动作分析,认为后手翻动作不管是上肢或下肢摆动要快,制动也要快(制动角约为554),这样完成整个动作才能做到低、平、快。在团身后空翻起跳阶段脚着地前,髋、膝、踝关节应主动蹬伸,缩短踏跳时间;下肢蹬伸的同时,手臂和躯干快速向后摆动,并及时制动,形成较好的动量矩传递,脚离地时相髋未完全打开,有利于腾空后团身。
Team backflip three weeks after the action is a plus-grade factor D-level difficult movements. By referring to the literature, expert discussions, combined with the action taken by our elite athletes, the author thinks that the back flip should be faster, the braking should be faster (the braking angle is about 554) Complete the entire action to be low, flat, fast. In the group backflip before the jump stage foot ground, hip, knee, ankle should take the initiative to Kengzhang, shortening the time to jump; lower extremity pedal stretch at the same time, the arm and torso swing back quickly, and timely braking, the formation of a better momentum Moment of transmission, when the foot off the ground when the hips are not fully open, is conducive to the sky after the group.
