EFECTOS DEL SALTO PROFUNDO EN LA FUERZA EXPLOSIVA DE LOS MIEMBROS INFERIORES DE LOS ATLETAS

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.
