Correlação entre saltos verticais e velocidade em jovens jogadores de futebol

Abstract

The aim of this study was to investigate the relationship between performance on tests of vertical jumps (Squat jump - SJ and Countermovement jump- CMJ), and performance in the speed test at distances of 10 and 20 meters in young soccer players. The study included 53 male young soccer players, mean age 15.72 years ±0.89, mean body mass of 66.96 kg ± 7.98 and mean height of 176.44 ± 7.68 cm. The study consisted of two types of jumps, the SJ and CMJ. The athletes performed three trials, preceded by two attempts of preparation. In the speed test each athlete performed three attempts were recorded and the time to traverse the distance from the initial 10m (0m to 10m) the final 20m (10m to 30m). These distances have been used based on the studies Chamari et al. (2004). The average of three trials of eachtest was used for statistical analysis. And to check the level of correlation between the variables we used the product moment correlation coefficient of Pearson (r) with significance level of p <0.05 based on the statistical package PSPP version 0.7.6. The results show that there is a significant and negative correlation between the performance of the SJ and performance in the Vel10 (r = - 0.31). Between the SJ andperformance in the Vel20 (r = - 0.62). For CMJ found a significant decrease and negative correlation with the test Vel10 (r = - 0.31) and the test vel20 (r = - 0.35). There is a low correlation between the SA test and test speeds (Vel10 Vel20) and between SCM and speed test (Vel10 and Vel20) in young soccer players.
