Methodology was clinical trial. 33 postmenopausal women (aged between 50 and 60) were randomly assigned to three groups: aerobic-resistance training (n=11), resistance-aerobic training (n=10) and control (n=12). Training interventions were performed for 8 weeks, 4 sessions per week. ANOVA with repeated measures was used to analyze the data.The results showed no significant differences in BMI, myostatin and follistatin concentrations among the three groups (P>0.05). The percentage of reduction in BMI was higher in A+R group and the percentage of reduction in myostatin and follistatin was higher in R+A group but this reduction was not significant. There was a significant difference between training and control groups in upper body muscular strength and endurance (P>0.05). There was a significant increase in upper body muscular strength and endurance in both training groups (P>0.05). The percentage of changes in the upper body muscular strength and endurance was higher in R+A group but this percentage was not significant. Based on these results, it can be stated that there were no significant differences between the different orders of concurrent training in the mentioned variables and postmenopausal women can use both training orders in order to increase upper body strength and endurance and prevent to increase myostatin and muscle atrophy.
