Abstract
ABSTRACT Introduction: Volleyball has become popular worldwide, and its athletic standard has risen. The skills of jumping into a net test athletes’ lower limb strength and speed. Objective: Study the effects of deep jumping exercises on the explosive strength in the lower limbs of volleyball athletes. Methods: Through the experimental method, logical analysis method, and mathematical statistics method, the kinematics and the results of the practical tests on the 8 muscles of the athletes’ lower limbs were studied. The training took place for 8 weeks of training intervention, and the characteristic biomechanical structure of the athletes’ lower limb muscles during the deep jump was established. Results: The landing time of the athletes in the deep jump group was improved, with a change of 0.03s. The deep jump group increased in time by 0.02s, indicating that the jumping ability was significantly improved. Conclusion: The deep jump training method reduces the time spent landing, with a strong level of evidence. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
