POSITIVE EFFECTS OF SIX MONTHS TRAINING PROGRAM ON INFLAMMATORY MEDIATORS IN YOUNG SOCCER PLAYERS

Despite the worldwide popularity of football, there is still insufficient data on the effects of the training process on the immune system, followed via serum values of cytokines measured during or following constant exercise. This study aims to assess the effects of a six-month programmed physical activity, on activity of inflammatory mediators in young footballers. The study included 26 players, male, aged 12-13 years, who participated in the six-month training program and 26 sedentary boys who are not entering of the previously mentioned program. Blood samples, which measured levels of the inflammatory mediators TNF-α (tumor necrosis factor alpha) and IL-6 (interleukin six) were taken before and after a six-month training programs. Significantly low values of IL-6 serum (34,73±33,23; 12,52±3,35; p=0,000**) were measured, while the concentration of TNF in the serum did not significantly alter after a 6-month training process. The results obtained in this way can be of an invaluable value in the organizing and dosing of physical activities in young football players.
