Abstract

Competitive swim a short distance and optimization of energy conversion control module

Author(s): YuYuan Xu

Under the premise of a range of reasonable conditions and assumptions, this study establishes athletes’ energy transformation model and optimal controlmodel for short-distance itemin competitive swimming and conducts model parameters estimation and fitting combines with actual data to find the optimal solution. Then this article discusses themost optimal allocation of the athletes’ physical strength and speed and points out that athlete should adopt the three-phase game strategy in competition. Specifically, the first phase is to acceleratewithmaximumthrust and reach themaximum speed at time; the second phase is maintaining uniform motion until at time, when ideally physical output is completed; the last phase is to decelerate and sprint.With this strategy the game can be completed in the shortest possible time, which provides theoretical support for technical training of the athletes and coaches
