In this paper, we establish a dynamic programming model of the motion process and a dynamic simulation model of the riding process, and use the genetic algorithm to simulate and optimize the speed and force distribution of the rider during the riding process. Specifically, we established a dynamic power curve model determined by a physiological mechanism (lactate heart rate), and derived the dynamic power curves of different genders, different levels, and different types of riders. In addition, we established a timed trial simulation and pacing strategy optimization model based on the micro-element method and random velocity generation, and used genetic algorithm to solve it. Further, we build a tempo strategy optimization model for team games. The optimal solution is obtained by using the improved objective function of team competition in genetic algorithm. Finally, a sensitivity analysis was performed for the considered models.
