the aim of the current research was the effect of a simple pyramid resistance training session with BCAA supplementation on IGF-1 levels during different periods of time in postmenopausal women. The current research was semi-experimental and applied. A total of 19 inactive postmenopausal women were selected. At first, the subjects were given the necessary information about the objectives and method of conducting the research, and each subject completed the consent form, physical activity and medical-sports readiness questionnaire. Then the subjects were randomly divided into two groups of simple + supplement pyramid resistance training (10 people) (age 52.20 ± 5.70 years, height 1.57 ± 0.01 cm and weight 88.76 ± 14.81 kg), Simple pyramid resistance training group + placebo (9 people) (age 50.89±4.25 years, height 1.60±0.01 cm and average weight 88.76±7.41 kg) were divided. The resistance training program was a pyramid with an intensity of 70-80% of one repetition maximum. The simple pyramid resistance training group + supplement consumed 0.1 gram per kilogram of body weight of BCAA powder in solution. Serum IGF-1 levels were measured before, 30 and 120 minutes after exercise. Two-way repeated measures statistical test was used to analyze the data. The findings showed that a simple pyramid resistance training session with BCAA supplementation has no effect on IGF-1 serum levels at different training times of postmenopausal women. Also, the difference between the groups in the level of IGF-1 after exercise was not significant. Probably, a simple pyramid resistance training session with and without BCAA supplementation at the rate of 0.1 gram per kilogram of body weight before and after training has no effect on the initial increase of IGF-1.
