Comparing the Effect of a One-Session Average-Intensity Resistance Training on the Growth Hormone Secretion in Active and Inactive Women

Background and Objective: Growth hormone not only effects the stimulation, division and growth of cells throughout the body during growth period but also leads to a decrease in the use of the carbohydrates and transfer of Lipids as sources of energy. The aim of this study was to compare the effect of a one-session average-intensity resistance training on the growth hormone secretion in active and inactive women Subjects and Methods: The demographic questionnaire completed by 100 female students, twenty, were randomly divided in two active and inactive groups. First, one repetition maximum participants in one-session resistance training were determined and then all participants engaged in protocol training with intensities of 50,60 and 70 % 1RMP. Blood samples were taken immediately before and after the training. Statistical measures of Pair t-test and Independent t- test and Analysis of Co- variance (ANCOVA) were used for data analysis. Results: resistance training decreases the secretion of growth hormone after training in active women while it increased the secretion of growth hormone after training in inactive women. However, this difference in growth hormone levels in both groups was not significant before and after training. (P<0/05).Conclusion: one-session average- intensity resistance training had no significant effect on either increasing or decreasing growth hormone. Therefore, to take advantage of the benefits of growth hormone, active and inactive persons should know that resistance training with moderate- intensity is not desirable for optimal secretion of growth hormone.
