Change of the body composition of professional soccer players of the club participant in the Brazilian Championship Series D 2010

Introduction: During the soccer game are performed different actions, with variations in different aspects: intensity, interval (characterized by the passive phase of the game), directions etc. Because it is a sport played on a large field, playing long time and decided to be at high intensities, the soccer goes about 11,5 km; this distance that's growing each season, by increasing the intensity of the game, advances in technology and sports physiology. Objective: This study examined changes in anthropometric variables of a professional soccer club participating in the Brazilian Championship Series D 2010, in three stages: pre-preparatory, pre-competitive and competitive. Materials and Methods: The following data were collected from 28 athletes age, weight, height and skin folds. The adopted protocol Jackson and Pollock (1978) - 7 folds -to calculate body density and like this determine the percentage of fat and fat-free mass. Results: The 28 athletes had a mean age of 24.8 +/- 4.1 years and mean height of 178.5 +/- 6.6 cm. Body weight showed no statistical differences between the moments. In contrast,% fat and fat-free mass showed statistical changes. Discussion: The data in this study coincided with those published previously. Conclusion: There was a statistically significant evolution of income, ie, gain of FFM and loss of FM.
