Comparison of the effect of ۳ and ۶ sessions of aerobic training per week with basic football training on growth hormone concentration in adolescent football players in Ilam

The purpose of this study was to compare the effect of ۳ and ۶ sessions of aerobic training with basic football training on growth hormone concentrations in ۱۳ to ۱۶ year old adolescent football players. This research was quasi-experimental research and was a practical component in terms of using the results.The statistical population of this study was ۱۳ to ۱۶ year old boys, ۳۰ of whom were purposefully selected and then randomly divided into three control groups (I), exercises ۳ sessions (II) and exercises ۶ sessions per week (III) were divided. The two training groups performed aerobic exercises for ۶ weeks with moderate intensity (۵۰-۷۵) percent of maximum heart rate along football school training for ۷۰ minutes per session. In this training program, the principle of overload was such that the intensity of training was initially ۵۰% of the maximum heart rate and every week ۵% was added to the intensity of training until it finally reached ۷۵%. Correlated t-test was used to compare within-group changes and one-way ANOVA was used to compare the differences between groups.Aerobic and basic football training ۳ and ۶ sessions for ۶ weeks both caused a significant increase in Total and Free growth hormone levels (P = ۰.۰۰۲ and p=۰.۰۰۸, respectively) and (P = ۰.۰۰۲ and P = ۰.۰۰۴). But there was no significant difference between the effect of these two types on growth hormone levels (P = ۰.۸۵۱ and P = ۰.۹۳۵, respectively).According to the results of present study, it should be said that aerobic training with basic football exercises has a beneficial effect on the secretion of Total and Free growth hormone can be useful in adolescents, but increasing the number of training sessions per week can not have a greater effect on secretion.
