Acute Effects of Dynamic versus Static Stretching on Aneorobic Power and Muscle Damage of Wrestlers

Abstract

The purpose of the presentstudy isto investigate the acute effects of statig. and dynamic stretching protocols (3 minutes stretching) on a maximal anaerobic Wingate Test (WT) of wrestlers. Fifteen male wrestlers (age, 23.2 +/- 2.6years; body mass, 79.2 +/- 10.7 kg) volunteered to participate in the study. Peak power, mean power, and average powers of the subjects were assessed during the Wingate test (WT) after static stretching and dynamic stretching. CK (creatine kinase) values were obtained before and after ach stretching protocols. Two WT were performed after stretching. Data analysis included paired t-tests. It was found that dynamic stretching caused more power deficits than static stretching and CK (creatine kinase) values of wrestlers increased more with dynamic stretching. Dynamic stretching caused significant decrease in power ascompared to static stretching, considered to be because of different duration of stretchingand continuous dynamic activity may have caused exercise induced muscle damage.
