踏跳是跳远技术中至关重要的环节。前人的研究以影片分析统计法为主,难以对人体运动的动作技术进行深一步的理论研究。根据运动项目特点,依据力学规律,将人体简化为由若干刚体并以铰相联的模型,对运动过程进行模拟是一种新颖的技术诊断、动作优化方法。人体力学模型可以将复杂的运动技 Jumping is a crucial aspect of long jump technology. The predecessors’ research mainly focuses on the film analysis and statistics, which makes it difficult to carry out further theoretical research on the movement technique of human body movement. According to the characteristics of sports events, according to the laws of mechanics, the human body is reduced to a model composed of several rigid bodies and connected by hinges. Simulating the movement process is a novel method of technical diagnosis and movement optimization. The human body mechanics model can incorporate complex motor skills
