Takeoff Technical Analysis in Long Jump Based on the Dynamics Statistical Model

摘要

In the professional and technical teaching, is jumping is the most key link in long jump techniques. From the mechanics' angle, takeoff jumping can be divided into steps-treading and jumping. The task of jumping is to acquire an appropriate takeoff angle of body gravity and more reasonable initial swinging velocity under rapid runup conditions, through reasonable takeoff movements to change human body movement direction. Therefore, whether athlete's takeoff technique is good or bad, is one of the important symbols of his sport level. Therefore, the fundamental factor to improve the performance of long jump is to master the full set of takeoff technology. From the point of statistical computing science and through the dynamics analysis, this study established a dynamic statistical model and discussed the influence factors of stepping and jumping stage, which provides a theoretical basis for athletes training.
