The purpose of this article is to conduct a systematic induction study of martial arts athletes' sports stretch, knee flexion and other kinetic energy and lower extremity explosive force in conjunction with the study of bovine physical energy burst. The literature data method, test method and mathematical statistics method were used to study the characteristics of the power and lower limb power of the young Chinese martial arts athletes of different ages and grades. The results show that with the increase of age and training years, the momentum of juvenile martial arts athletes' stretching and flexing their knees gradually increases. 20-year-old martial arts athletes have significantly higher dynamics such as knee flexion than 18-year-old athletes, and there is no significant difference between the two. The former has a higher extensor / knee flexion ratio than the latter. On the 10m standing full-speed running test, the performance of the 20-year-old martial arts athletes was significantly better than that of the 18-year-old martial arts athletes. However, there is no obvious difference between the results of standing full-speed running at 30m, standing still vertical jump, and original underground squat vertical jump, indicating that the lower limb explosive power training has not received enough attention with age.
