我国竞走技术的运动学特征与发展趋向

Kinesiological Feature and Development Trend of Chinese Race-Walking Technique

通过生物力学手段的测试与分析,寻找出适合我国竞走技术自身发展的方向及突破点,为提高竞走运动的整体发展水平做出相应努力。经过摄像、解析与分析,得出以下结果:竞走在"定义"不断完善的各个时期,教练员、运动员必须按照"定义"和规则所允许的范围,改进运动技术、提高运动成绩;中国运动员竞走技术的前支撑阶段,没有明显的屈腿现象,双支撑阶段没有出现明显的、肉眼可见的腾空现象;中国竞走运动员因受身体条件制约,其技术应当在保证符合竞走定义的前提下,继续发扬和保持"高步频"的特点;中国运动员在保持自身技术特点的基础上,应将发展的侧重点置于适度增加步长之上。

Sports biomechanical device is employed to find out the development trend and breakthrough of Chinese race - walking and endevour to improve the overall development level of race - walking. It is concluded that during each period of perfecting the definition of Chinese race - walking technique, coaches and athletes should subject to the ＂definition＂ and rule, and improve the technique and performance. There is no clear leg -bending in Chinese race walkers in the early propping stage, and no clear or visible rising into the air in the double propping stage. After satisfying the definition of race walking, Chinese race walking technique should keep and carry on ＂high stride frequency＂ and the key to development should lie in a moderate increase in the stride length.
