SILVA-JUNIOR, C.J. et al. Relationship between the sprint and vertical jumps' power in young soccer players. Motri. [online]. 2011, vol.7, n.4, pp.5-13. ISSN 1646-107X.

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.
