Introduction
Aging is concomitant with muscle atrophy and common alterations in hypertrophic hormones. Besides, resistance training and protein consumption modify these changes. So the aim of the current study was to assess the effects of progressive resistance exercise and soy milk on serum levels of growth differentiation factor 8 on aged women.
Material & Methods
This was quasi-experimental study design. Twenty-four aged women randomly distributed into control (n=8), progressive resistance exercise + soy milk (n=8), and soy milk (n=8) groups and took part in exercise-diet intervention for 12 weeks (3 d/w). Anthropometric features, ability, and serum levels of growth differentiation factor 8 were collected before and after the interventions. All data was calculated by two way ANOVA and Bonferroni post-hoc at p<0.05 with stata 12. 
Results
Growth differentiation factor 8 levels significantly diminished in both progressive resistance exercise + soy milk and soy milk groups compare with control and pre-intervention (p<0.05). Also, ability of the progressive resistance exercise + soy milk group illustrated significant improvement compare with control and pre-intervention (p<0.05). There were no alteration in anthropometric features of non-groups (p>0.05).
Conclusion
Twelve-week exercise-diet intervention resulted in decrease of growth differentiation factor 8 of aged women which could reverse age-related skeletal muscle atrophy. Also, the ability of older women develop via exercise-diet interventions that in line with positive functional-physiological effects of exercise and protein on aged women skeletal muscle. Consequently, social activities and life quality could promote.
