【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。
[Abstract]:The Rope skipping is developed on the basis of single and double Rope skipping, and it is one of the most difficult movements in rope skipping. Through the biomechanical analysis of the Rope skipping technique with positive third Row and single Rope skipping, It is found that the movement amplitude of lower extremity joints in the stage of the positive third rocking is greater than that of the single shaking, and the center of gravity rises faster in a short time, the joints have obvious flexion, the lag time is longer, and it is more favorable for the rope to pass through the soles of the feet quickly. At the stage of landing buffer, the buffer is more sufficient, the ground force is larger, and the rope shaking speed is faster and presents a certain rhythm change.
