Rela??o entre as potências de sprint e salto vertical em jovens atletas de futebolKeywords: soccer, muscle power, speed, young athletes. Abstract: muscle power, speed and acceleration are generally considered important determinants of high performance in sports. thus, the aim of this study was to evaluate the relationships between 10- and 30-meter sprint power and vertical jump power among young soccer players. the participants of the study were 143 male soccer players from the categories under-20 (n = 34), under-17 (n = 43) and under-15 (n = 66), which performed vertical jump test, 10-meter sprint test and 30-meter sprint test. the results indicated weak to moderate correlations when the absolute values of time and maximal height were compared (r = -.47 to .71). when the values of power obtained from tests were compared, moderate to strong correlations were found (r = .74 to .87). the results suggest that implementing these three tests would be important because they measure different motor skills. moreover, the correlation between vertical jump power and 30-meter sprint power was surprisingly strong. nevertheless, further studies are required in order to improve understanding about these power relationships.
