Efeito do treinamento pliométrico sobre força explosiva, velocidade e agilidade em atletas de voleibol feminino

Abstract

This work aimed to investigate the effect of plyometric training on explosive strength, speed and agility of female volleyball athletes. These capabilities are important as the mode requires fast movement with changing directions for the best performance. Sixteen volleyball players, aged between 14 and 15 years old, were selected and divided into two groups: experimental (GE N = 8) that underwent plyometric training and volleyball training; control group (CG N = 8) that underwent volleyball training only. For the evaluation of pre and post intervention capacities were applied the vertical impulsion, horizontal impulsion, medicine ball, square test and speed shuttle run tests. The data obtained were statistically treated by Student's t test. The EG results regarding the square and medicine ball tests did not show significant differences (p> 0.05) and the vertical impulsion, horizontal impulsion, and shuttle run tests showed significant differences (p <0.05). The group CG obtained significant result only in the horizontal impulse test (p <0.05), and vertical impulse test, medicine ball, square and shuttle run did not express significant improvements (p> 0.05). However, it is clear that for GE there was a positive result regarding the physical capabilities of explosive lower limb strength and velocity. In contrast, the CG showed no change in the performance of the upper and lower limb explosive strength physical abilities in horizontal jump, agility and speed, but only a slight change in the lower limb explosive strength capability in the horizontal impulse test.
