Theory and Practice of High-Level Sprint Training Based on Accurate Sectional Timing

There is an obvious gap in sprint level at home and abroad, and there are different opinions on the reasons. According to the analysis, physical energy and its distribution in each segment are the main factors restricting the sprint performance in China. Different from middle and long-distance running, we must rely on accurate sectional timing technology to master the law of speed-physical energy change in the process of sprint. Each stage is an integral part of the whole dash process, and each part restricts each other. Each stage has a relative best achievement. Simply pursuing the optimal state of segment is not only not helpful to the final result, but also counterproductive.
