AIM: The purpose of this study was to examine the changes in anthropometric and physical fitness characteristics in professional soccer players at the beginning of the season, after pre- season camp and during in-season.
METHODS: 17 players were evaluated on 3 different periods (June: T0, August: T1 and December: T2). Each evaluation consisted of anthropometric measurements (body mass, height, and body fat) and physical fitness tests (counter movement jump (CMJ), counter movement jump with arm (CMJA), 10-m sprint, 30-m sprint and maximal aerobic speed (MAS)).
RESULTS: Comparatively with T0, all physical performances achieved in T1 were significantly improved (MAS: p<0.01, 10-m sprint: p<0.05, 30-m sprint: p<0.05, CMJ: p<0.01, and CMJA: p<0.05). The decrease in training load during in-season is associated by significant decrement in MAS (p<0.05) and preserved performances in 10 (p=0.85) and 30-m sprint (p=0.99), CMJ (p=0.34) and CMJA (p=0.87) completed in T2 comparatively with T1. Physical fitness performances achieved in T2 remain higher than that obtained in T0 (MAS: p<0.01, 10-m sprint: p<0.01, 30-m sprint: p<0.05 and CMJ: p<0.05) and remain similar for CMJA (p=0.13). No significant changes were observed in anthropometric measurements throughout the study.
CONCLUSION: The main finding of this study was that a greater training load accomplished during pre-season could lead to an improvement in the physical fitness during in-season in professional soccer players. We suggest that this higher training load meets the needed required for the professional soccer although the training loads are declined during in-season.
