Abstract
The aim of this study was to assess the fatigue specific functional and metabolic factors changes in response to a period of high intensity aerobic training in soccer players. 18 soccer players from Azadegan league competitions were selected and randomly divided into two groups (training; 12 players, control; 6 players). Mean ± SD age, height, weight and percent body fat for players were 21.88±2.24 years, 174.22±5.33 cm, and 67.77±5.7 kg and 12.38±3.29 percent, respectively. Four weeks of high intensity aerobic interval training was performed three times a week at the end of the soccer training sessions. The values obtained before and after the training period include lactate concentration, pyruvate level and PH level and time to exhaustion which were compared using un-paired Student’s t–test, repeated measures ANOVA and LSD post hoc procedure. Findings showed that 4-week training period did not cause significant changes on maximum anaerobic power and fatigue index. In addition, training period did not have any significant effect on lactate to pyruvate ratio and PH level. It is concluded that four weeks of high intensity aerobic interval training probably have little but insignificantly effect on aerobic metabolism and fatigue outbreak in soccer players
