跨栏步技术既表现了跨栏跑的项目特点,又是决定跨栏跑技术和成绩优劣的关键环节,多年来,人们在实践中逐步认识跨栏步的运动规律,获取了一定的经验,也发现了运动员在完成跨栏步中摆动腿技术动作存在一些问题,如整个跨栏步中摆动腿运动路线,膝关节折叠及打开时机;下栏着地支撑等问题,即在跨栏步中摆动腿技术不能体现合理性、经济性、实效性。本文试图针对上述问题,依据生物力学原理,借鉴优秀跨栏选手有关资料及本人多年教学训练总结,就跨栏步中摆动腿技术力学机制及正确技术予以阐述。
Over the years, people gradually realized the law of movement of hurdle step in practice, acquired some experience, and also found out that the hurdling technique has shown both the characteristics of the project of hurdle race and the key links that determine the skill and performance of hurdle race. There are some problems with the athlete’s swinging leg during the hurdling step, such as swinging the leg movement route throughout the hurdling step, folding and opening of the knees, supporting of the underneath bar, etc., that is, the swinging leg technique in the hurdle step can not reflect the rationality , Economy, effectiveness. This paper attempts to address the above problems, based on the principle of biomechanics, drawing on the information of excellent hurdles players and my many years of teaching and training summary, hurdle leg mechanics mechanism and correct technology are described.
