在跨栏技术中,摆动腿的过栏技术对提高跨栏运动成绩起着至关重要的作用。然而国内跨栏运动员做跨栏步动作时,摆动腿的小腿动作较为被动、消极,制约了跨栏技术及成绩的提高。在教学训练实践中,我们认为:必须准确而严格地控制住各技术环节的完成,即人体各部位肌肉用力的时间和空间规格(人体各部位运动的快、慢、早、晚及幅度大与小等),才能对跨栏技术和成绩的提高起到积极的作用。
In the hurdling technology, swinging the leg over the bar technology to improve the performance of hurdles plays a crucial role. However, when domestic hurdler do hurdling action, the leg movement of swing leg is more passive and negative, which restricts the hurdle technology and the improvement of result. In teaching and training practice, we think: we must accurately and strictly control the completion of all technical aspects, that is, the human body parts of the muscle force of time and space specifications (body parts of the movement of fast, slow, early, late and the magnitude and Small, etc.) in order to hurdle technology and improve the score play a positive role.
