Power Output Differences in the Context of Dynamic Stretching in Young Male Athletes

Abstract

"Introduction. Static stretching is generally performed in sport and clinical settings, although dynamic stretching is increasingly being used before exercise and competition. There is strong evidence that a decrease in muscle strength can be the result of longer durations of static stretching, a phenomenon called stretching-induced force deficit. Objectives. The aim of this paper was to determine the jumping power output differences before and after dynamic stretching in young male athletes. Materials and Methods. The participants in this study were young male athletes (N = 18), aged from 14 to 16 years old that underwent two measurements on the MGM-15 carpet. Results. There was a significant statistical difference in the scores between the control and after dynamic stretching conditions. This means that the dynamic stretching had an influence over the power output of the subjects. Conclusion. The results revealed that the power output was significantly improved (increased) after dynamic stretching compared to control measurement. Furthermore, dynamic stretching should be performed in order to increase the power output performances of jumping. Keywords: dynamic stretching, power output, male, athletes, jumping "
