Influência de um programa de treino de Pliometria em jogadores de rugby ao longo de 12 semanas

Abstract

Background: The performance in Rugby are dependent on the strength levels of each athlete, in which the explosive power plays a key role. Therefore, it is important to understand how the plyometric training constitutes an effective method in the development of the youngest players of this sport. Objective: To assess the effect of a plyometrics training over 12 weeks in young rugby players. Sample: 33 male rugby players, divided into 2 groups: experimental group (GE) who performed 2 complementary sessions of plyometrics per week (μ 16 years, 3 months) and control group (GC) that did not perform any session (μ 16 years, 4 months). Results: There was a significant improvement at the end of 12 weeks in the following tests: SV (t=-6,92; p<0,01), SH (t=-5,09; p<0,01), SH1AD (t=-3,93; p<0,01), SH1AE (t=-4,55; p<0,01), TSD (t=-5,99; p<0,01), TSE (t=-3,57; p<0,01), LF (t=-7,14; p<0,01), Décuplo (t=-3,88; p<0,01) and LD (Z=-3,20; p<0,01) in GE and in the SV (t=-3,75; p<0,01), SH (t=-3,80; p<0,01), SH1AD (t=-2,60; p<0,05), SH1AE (t=-2,40; p<0,05), LF (t=-4,57; p<0,01) and LD (Z=- 2,81; p<0,01) in GC. When comparing the values accomplished by the dominant leg and the non-dominant leg between GE and GC, statistically significant differences were observed in the S1A test for the dominant leg (T=- 4.28; p <0.01) and for the non-dominant leg (T=-4.168, p <0.01) as in the TS1A test for the dominant leg (T = -6.05, p <0.01) and for the non-dominant leg (T=-3,45; p<0,05) in GE. Conclusions: (I) There was an evolution of the results obtained in the initial moment, both in the evaluation of jumps and of the launches; (II) The plyometric training induces improvements in strength levels; (III) The plyometric training had no influence on speed levels; (IV) Athletes who perform plyometric training have a greater ability to carry body weight on a single leg; (V) There was an improvement in strength levels in both the dominant and non-dominant legs.
