跨栏跑是田径项目中技术性很强,动作较复杂,全身协调配合,对速度、力量、柔韧、灵敏、耐力等要求较高的项目。一、研究目的与意义跨栏步是跨栏跑技术中的关键,在跨栏步中,其摆动腿动作正确与否将直接影响跨栏步动作质量。依据跨栏步中摆动腿动作应遵循的生物力学原理,借鉴世界优秀跨栏运动员的摆动腿技术动作加以分析研究,在此基础上,对 Hurdle race track and field project is very technical, complex movements, body coordination, the speed, strength, flexibility, sensitivity, endurance and other items demanding. First, the purpose and significance of the study Hurdle step is the key to hurdle technology, hurdle leg in the hurdle step, the correct action or not will directly affect the hurdle step action quality. According to the biomechanical principle that the swinging leg action should follow in the hurdling step, the author analyzes and studies the technical action of the swing leg of the world’s outstanding hurdle athletes. On this basis,
