Mechanical Muscle Response in the Major Pectoralis in Swimmers Through the use of Tensiomiography

Abstract

Tensiomyography (TMG) is a non-invasive method of muscle evaluation, it is used to analyze the muscle response to astimulus given muscle tone. The objective of this study is to analyze the muscular mechanical response in the pectoralis major (PM) in swimmers after the development of a lactic resistance training developed in the crawl style. For this, a totalof 30 male swimmers belonging to the junior and absolute categories, carried out a lactic resistance training session withan analysis of the right PM. The results show changes with an increase in the value of pos in Td (p <0.584), in Tc (p<0.363) and a decrease in pos in Dm (p <0.178), in Tr (p <0.125) and in Ts (p <0.004), the latter being statisticallysignificant. In conclusion, a lactic resistance session causes changes in the muscular response in swimming.
