Sports Science Teaching of Athletics Based on Nonlinear Mathematical Equation

To study the teaching of sports science in athletics, this paper adopts the method of a nonlinear mathematical equation, According to the explosive power = force * speed and hill force speed equation, the best matching value between the load weight and the muscle contraction speed when the athlete reaches the maximum explosive power is obtained by the mathematical method, to achieve the objective of quantifying and scientifying the maximum explosive power training method according to the individual ability of the athlete. The results show that the training intensity is slightly lower than the optimal strength load (about 30%F0) and faster than the optimal movement speed. Jumping events adopt load weight higher than the optimal load to 50% F0 and load intensity slightly slower than the optimal speed combination for training; Conclusion: According to the characteristics of track and field events, this paper discusses the application of the research results in the training of athletes’ explosive development in different track and field events, to achieve better training effect and improve students’ athletic ability.
