摘要：The aim of this study was to verify changes in anthropometric and physiological characteristics of the 17 years category of players in a professional club. We selected a non-probability accidental 26 players who have an average age of 16.16 ± 0.75 years at the start of the pre-season and 16.36 ± 0.75 years at the end of the preseason. We evaluated anthropometric variables height (cm), weight (kg), fat percentage (% g), fat mass (kg) and muscle mass (kg), and physical variables (Yo-Yo Intermittent Recovery Test (m), Yo-Yo Endurance Test (VO2max in ml / kg / min), speed (20m), Agility (seconds) and two squast jump tests (cm) and Contramoviment(cm). For statistical analysis, arithmetic average descriptive statistics and standard deviation were used, and to verify the significant differences, the Student test and a test with a specificity of Tukey were used (p <0.005). The results showed that no significant differences were found for total body weight, muscle weight and the specific resistance of yo-yo Recovery test. However, the eight training microcycles were statistically sufficient to alter the percentage of fat, sum of skinfolds and fat weight, and also to improve aerobic power, speed, agility, explosive strength and elastic explosive strength, respectively.
