与短跑成绩相关的因素有很多:步频、步幅、速度、速度能力、爆发力,以及肌肉、关节的柔韧性和协调性;还有运动员的心理素质和技术水平等。其中有三个因素与提高短跑成绩最相关。一、正确的技术动作运动员能否掌握好合理、正确的技术动作要领,是今后能否达到高水平所必须具备的基本条件。因为短跑是一项周期性的运动,全程要反复跑几十步。一点微小的错误就变成了大问题。假如每一步的步幅能够加长3厘米,那么,50步就可以赢得1.5米的优势。技术动作的规范合理主要表现在跑的动作结构上要更加符合运动生物力学的原理,使
There are many factors related to sprint performance: stride frequency, pace, speed, speed ability, explosive force, and muscle and joint flexibility and coordination; as well as athlete’s psychological quality and technical level. Three of these factors are most relevant to improving sprint performance. First, the correct technical action Athletes can grasp a reasonable and correct essentials of technical action, the future can reach a high standard must have the basic conditions. Because dash is a periodic exercise, the entire process should be repeated several tens of steps. A minor mistake becomes a big problem. If the pace of each step can be lengthened 3 cm, then 50 steps to get the advantage of 1.5 meters. Technical specifications of the movement is reasonable mainly in the movement of the structure to be more in line with the principles of exercise biomechanics, so that
