Preliminary Study on the Changes in Muscle Composition in Sports Games

Abstract

In order to evaluate how volleyball and basketball games and their corresponding training sessions coincide with changes in the composition of the muscles put to work, we used the method of the repeated effort at submaximal weight to test a lot of volleyball players and one of basketball players. The results show that the muscles involved in the specific effort required by volleyball exercises retain their typical proportion in muscle fiber types, while in the case of basketball the typical proportion of fast-twitch fibers is replaced by the slow-twitch fibers.
