Abstract
Research Aim: Resistance exercise training (RET) is potential stimulus to induce hypertrophy and it can be increased through processes related to myokines which can be synthesized by skeletal muscle. Resistance exercise training with nutritional intervention has the potential to be a non-pharmacological stimulus to increase hypertrophy. Therefore, the purpose of this article was to contribute hypertrophy literature by assessing the effects of Weight-Bearing resistance training with omega-3 supplementation on some factors involved in muscle hypertrophy in young female.
Research method: Thirty-two healthy women (Age: 23.38 ± 3.6 years, weight 59.73 ± 8.27kg, height: 135.20 ± 4.92 cm and body mass index: 21.91 ± 2.57 kg/m²) were selected and randomly divided into four groups of control, consumed omega-3 supplementation (3g/d), and a combination of RET + omega-3 group. Then, subjects entered to 6 weeks of Weight Bearing resistance training. Saliva measurements were performed 48 hours before and after the start of the project in two stages of pre-test and post-test. Measurement of the levels of IGF-1,myostatin and Irisin was performed by ELISA method. The dependent t-test and one way ANOVA was used to analyse data by SPSS 26 software.
Findings: The results revealed that the level of myostatin in the training group was significantly different(P<0.05) and there was no statistically significant changes were observed for the level of both IGF-1 and Irisin (P> 0.05). It can be concluded that Weight-Bearing resistance training can reduce myostatin and prevent atrophy in young females.
