Introduction: The purpose of this study was to comparison of small-sided games (SSG) and sprints on testosterone, cortisol, blood cell count, and physical fitness indices in teenage soccer players.
Material & Methods: In this Quasi-experimental study, thirty-six teenage athletes (13.55±0.53) were randomly divided into control (CG), SSG, and sprint groups (SG). The subjects in the SG underwent 45-minute short bursts of sprinting. The SSG group exercise program 45 minutes consisted of 8×3 minutes with 3 minutes of active recovery between sets and was performed on a small Football pitch without a goalkeeper. In contrast, the control group continued their usual routine activities for 4 weeks (3days/week). Basal levels of K-TEST, RSA, and YO-YO tests, as well as blood indices of testosterone, cortisol, and blood cells, were measured before commencement and after 4 weeks of training.
Results: The results indicate that sprint training led to a significant increase in testosterone, testosterone to cortisol ratio (T/C ratio), RBC, and WBC compared to the control group and a significant decrease in cortisol and agility performance. SSG also caused a significant increase in testosterone, T/C ratio, RBC, WBC, Systemic Immune-Inflammation Index (SII), and aerobic performance, with a significant decrease in cortisol and agility performance. Additionally, in the control group, cortisol showed a significant increase, and the T/C ratio was significantly decreased (p<0.05).
Conclusion: The present study revealed that both sprint and SSG training individually can have desirable effects on testosterone, cortisol, T/C ratio, WBC, RBC, and agility tests. Sprint and SSG were found to be effective for these factors. The SSG training program increases WBC, SII, and aerobic performance.
