Abstract

The purpose of this study was to examine changes in anthropometric and physical fitness parameters in male professional soccer players during the competitive soccer season.


42 soccer players (mean ± SD; age= 25 ± 5.2 years, mean height= 177.3 ± 6.74 cm, mean body mass= 75.8 ± 5.97 kg) were tested. Variation in body composition and performance in squat jump (SJ), countermovement jump (CMJ), Abalakov jump (ABK), and VAMEVAL maximal incremental running test were evaluated in 3 time points (E1 before the season, E2 at the end of pre-season period, and E3 during the middle of the season) throughout 2 consecutive seasons. Individual percentage of training completion was quantified.
From E1 to E2, VO and maximal aerobic velocity significantly increased (61.99 ± 2.78 vs. 63.87 ± 2.80 ml∙kg-1∙min-1 and 19.19 ± 0.77 vs. 19.70 ± 0.70 km∙h-1, respectively) and the percent body fat and percentage of skeletal muscle were significantly different (10.99 ± 1.02 vs. 10.34 ± 0.73 and 47.96 ± 0.96 vs. 48.63 ± 0.83, respectively). No differences were observed in SJ, CMJ, and ABK between 3 evaluation moments. Influence of individual percentage of training completion was correlated to changes in muscle weight (E1 to E2; r=0.54, and E2 to E3; r= 0.39).
This study suggests that male professional soccer players with high individual percentage of training completion have higher capabilities to increase or maintain muscle mass throughout the season.
