Anthropometry, Body Composition, and Physical Fitness in Semi-Professional Soccer Players: Differences between Sexes and Playing Position

Performance in soccer has been associated with specific morphological characteristics. Few studies have simultaneously compared the relationships between physical fitness and body composition in both sexes. This study aimed (i) to analyze the differences in anthropometric parameters, body composition, and physical fitness between sexes and playing position in soccer players and (ii) to determine the relationship among anthropometric and body composition parameters to physical fitness parameters according to sex. A total of 50 soccer players (men: n = 26; women: n = 24), participated in the study. Assessments of nutritional intake, anthropometry, body composition, and physical fitness (isometric strength, maximal aerobic capacity, and vertical jump) were carried out. Differences between sexes were observed in all anthropometric and body composition parameters (p < 0.001). There were differences between midfielders and forwards in fat percentage (p < 0.05). Regarding physical condition, differences were found between sexes in all tests performed (p < 0.001). In men soccer players, there were significant correlations between body composition and aerobic capacity (p < 0.05), while in women soccer players, there were correlations with isometric strength tests (p < 0.05). Anthropometry, body composition, and physical fitness differed between sexes. Fat percentages were different among playing positions. There were relationships between anthropometry and body composition with physical fitness. Knowledge of anthropometric and fitness characteristics by playing position and gender in soccer players could help develop specific training programs.
