The effect of resistance training using body weight and omega-3 supplementation on salivary testosterone and cortisol hormones in young non-athletes’ women.

Introduction and purpose: It is important to improve the anabolic state compared to the catabolic state in the body, especially through hormonal changes. The aim of this study is examine effect of resistance training using body weight and omega-3 supplementation on salivary testosterone and cortisol hormones in young non-athlete women.Materials and methods: In this semi-experimental study, 40 young women after obtaining written consent were randomly divided into four exercise+supplement groups. Exercise+placebo, supplement and control were divided. The resistance training program was performed three sessions a week with an intensity of 55-70% of one maximum repetition for six weeks. Three 1000 mg omega-3 capsules were prescribed daily in three meals. The maximum strength of the upper and lower body muscles as well as the levels of testosterone and salivary cortisol hormones before and after the exercise and supplementation protocol were evaluated and the resulting data were analyzed by the analysis of variance test. Results: : Six weeks of resistance training using body weight and omega-3 supplementation alone and interactively did not have a significant effect on the levels of salivary testosterone (training, p=0.08; Supplement, p=0.72; training× Supplement, p=0.81) and cortisol (training, p=0.44; Supplement, p=0.38; training× Supplement, p=0.31) hormones in young women. Also, although the interactive effect of exercise + supplement on the maximum strength of lower body and upper body muscles increased by 1.47 and 1.63%, respectively, these changes were not significant.
