Efecto de un programa de ejercicios pliométricos específicos, para el desarrollo de la fuerza explosiva en el voleibol categoría 13-15 años

Abstract

Volleyball is a cooperative opposition sport, where the explosive strength of the lower limbs is of great importance for the development of the game, especially in some basic fundamental forms such as attacks. The objective of this paper was to analyze the effect of a specific plyometric exercise program through sports implements (stretch bands, sports training parachute, resistance harness and vertical jump trainer) for the improvement of the explosive strength of the vertical jump in volleyball in the junior male athlete´s category. For this, two groups were assigned, a control group from the Sports Federation of Azuay (FDA) and an experimental group from Unidad Educativa Santana (Santana). This experiment consisted on the control group carrying out a traditional program of plyometric exercises versus the experimental group following a program with modern sports equipment. Each, executing 4 jumps, blocking range, attack range, Abalakov and Squad jump, the latter two being measured through a jump platform. The duration of the program was 12 weeks of work, in which, two measurements were taken, at the beginning and end of the program, obtaining results of the differences between the two groups: Attack range 0.1046 ± 0.06 intervention group, 0.1092 ± 0.05 control group, blocking range 0.087 ± 0.02 intervention group, 0.113 ± 0.05 control group, Abalakov 5.415 ± 2.60, 3.066 ± 2.63, Squad Jump 4.708 ± 3.69, 2.550 ± 1.70 intervention group and control group respectively. This study concludes that significant improvement in the explosive strength of the lower limbs was evident in the intervention group, in the Abalakov and Squad Jump jumps, due to the use of modern sports implements to improve the jump.
