摘　　要：正三摇跳绳是在单摇、双摇跳绳的基础上发展而来,是跳绳技术难度系数最高的动作之一。通过对正三摇和单摇跳绳技术动作的生物力学分析,发现正三摇在蹬地阶段下肢关节活动幅度、蹬地力较单摇更大,短时间内重心上升速度更快;腾空阶段各关节有明显的屈,滞空时间更长,更利于绳子快速通过脚底;落地缓冲阶段缓冲更充分,地面作用力更大;摇绳速度更快并呈现出一定的节奏变化。The clockwise triple-skip technical move is developed on the basis of the single-skip and double-skip techniques,one of the moves with highest rope skipping technical difficulty coefficients.By carrying out a biomechanical analysis on the clockwise triple-skip and single-skip rope skipping technical moves,the authors revealed the following findings:,as compared with those of single-skip rope skipping,at the stamping stage,the clockwise tripe-skip rope skipping move had a larger low limp joint movement amplitude,a greater stamping force,and a faster center of gravity ascending speed in a short time;at the take-off stage,all the joints had obvious flexion,a longer hang time,which is conducive to the rope passing through the sole quickly;at the buffer stage,the clockwise triple-skip rope skipping move had more thorough buffering,a greater ground acting force,a faster rope swinging speed,and showed a certain change of rhythm.
