PHYSICAL CHANGES DO NOT OCCUR IN-SEASON IN SOCCER
daSilva, S. G., Osiecki, R., Arruda, M., Moura, J. A., & de Campos, W. (2001). Changes in anthropometric variables and in anaerobic power and capacity due to the training season in professional Brazilian soccer players. Medicine and Science in Sports and Exercise, 33(5), Supplement abstract 890.
Professional soccer players (N = 20) were tested pre-season and then at 10-week intervals for the remainder of the competitive season.
No changes in anthropometric measures, Wingate Test performance and associated anaerobic capacity indices, skinfolds, body weight, or body composition were observed.
Implication. Training and competing in-season are insufficient stimuli for producing anthropometric or physiological improvements in professional soccer players.
