CORRELACÃO ENTRE O DESEMPENHO DE SALTOS E SPRINTS NOS DIFERENTES ESTÁGIOS PUBERAIS EM JOGADORES DAS CATEGORIAS DE BASE DO FUTSAL.

Abstract

Objective: To verify the correlation coefficient between the performance of jumps and sprints in the different pubertal stages in players of futsal base categories. Methods: We evaluated 76 male players (8-16 years old), who were divided according to their pubertal stage. All of them performed the squat jump (SJ) and countermovement jump (CMJ), sprint straight line (SSL) and with change of direction (COD), in addition to the anthropometric evaluation and body composition. The pubertal stage was evaluated by the peak height velocity (PHV) in which it differentiated the players in prepubescent (PRE-pub), pubescent (PUB) and postpubertal (POS-pub). The Shapiro-Wilk normality test was used and when comparing the morphological and performance variables between the stages, the ANOVA one way with Tukey post hoc was used. To analyze the correlations between performance of sprints and jumps, the Pearson correlation test was used and in all analyzes a significance level of p < 0.05 was adopted. Results: In the correlation analysis with all the subjects, positive, strong and significant correlations were verified between SJ vs. sprints (r = 0.50 to 0.55, p < 0.01) and CMJ vs. sprints (r = 0.51 to 0.60, p < 0.01). However, when differentiating by the pubertal stage, only in the PRE-pub was a positive, strong and significant correlation between SJ vs. sprints (r = 0.55 to 0.61, p < 0.01) and CMJ vs. sprints (r = 0.55 to 0.63, p < 0.01), while positive, weak and non-significant correlation was demonstrated in PUB between SJ vs. sprints (r = 0.13 to 0.17, p > 0.05) and CMJ vs. sprints (r = 0.17 to 0.24, p > 0.05) and for the POS-pub between SJ vs. sprints (r = - 0.12 to 0.17, p > 0.05), with negative and positive correlations for SSL and COD, respectively, and CMJ vs. sprints (r = 0.17 to 0.24, p > 0.05). Conclusion: The correlation coefficient between the performance of VJ and sprints changes according to the pubertal stage that the player is in. It is necessary to exercise caution in the appropriation of the use of strength training, through the VJ, aiming at improving the speed for athletes of the basic categories, especially considering the pubertal stage, in which only in the PRE-pub athletes the positive correlation, strong and significant was observed.
