Utilização da porcentagem relativa da creatina quinase para controle de carga de treinamento ao longo de uma temporada competitiva de futebol profissional

Abstract

Plasma concentrations of creatine kinase [CK] have been used as an indicator in different sports, among them football, related to skeletal muscle damage. However your individual variation for individual and very high which creates a difficulty to evaluate your changes and modify individualized training. Thus, the aim of this study was to analyze the kinetics of plasma creatine kinase individually for games density (1versus 2) with serial samples at different times of post game (CKcont) during a competitive season of professional football featuring the use CK on (CKrel) the maximum creatine kinase (CKmax) as a form parameter to control training. We tried to keep the collection in the periods established in the literature and after 1, 2, 3, 4, 5, respectively pos1 the peak registration period CK 20 to 30h after game by following these collections to the post 5 that records as the return to normal levels that occur after 60 to 70h of the game. The study included 32 football players in a professional club the first division of the Brazilian championship, aged between 19 and 37 years, weight 78.8, 9.0% fat, 1.79 height, lean mass 71.8% and VO2max of 53.1 (MEAN - x). The analysis of CKcont CKrel and showed significant differences (P <0.05) for the comparison of 1 and 2 months competitive cycle compared to the 10 and 11 months (end of the competitive cycle) showing that matches density influences the [CK] athletes and that they demonstrated support the demands of the musculo skeletal system.
