The Effect of Long-distance Jump Training on the Athletes' Performance in the Late Course of Sprint in Track and Field

摘要

The track and field sprint, which is an anaerobic energy supply project, is a typical project of speed competition. Its primary energy material ATP - CP which will run out in 4 to 5 seconds, can only maintain the energy of the athletes for 30-40 meters. How to improve the late course performance of the sprinters is the key factor to get a better result. Based on the teaching practice of many years, the author adopts a new training method to improve the performance of athletes in the late course of the track and field sprinting. The method mainly adopts long distance jump training, supplemented by short and medium distance jump training, and combines the traditional running high-speed endurance level training. The author sets up the experimental group, which a long jump training is given priority to, and control group, which adopts traditional high-speed endurance level training. By comparing the experimental results of two groups of athletes, the author analyzes the sprint mechanism and the energy supply and saving system to explore how does the training of long distance jump affect the athletes' performance in the late course of sprint in track and field.
