Introduction: Consumption of pomegranate extract along with endurance training induces an improvement in blood flow, an increase in resting metabolism and weight loss. However, the effect of its consumption along with strenght training on body composition and weight control has not been studied.  The aim of this study was to investigate the effect of 8 weeks of strength training with pomegranate extract on resting metabolic rate, hypertrophy and muscle strength of inactive male students.
Materials and Methods: In this quasi-experimental study, 42 inactive boys were selected by voluntary sampling and after obtaining written consent from them, were randomly divided into four groups: strength training (n = 11), strength training with pomegranate extract (n = 11), pomegranate extract (n = 10) and control (n = 10). The strength training program was performed for 8 weeks, 3 sessions per week and included 2 movements for the upper body (barbell chest press and barbell shoulder press) and 2 movements for the lower body (front leg and machine leg press). The subjects in the strength training with pomegranate extract group (half an hour before training) and the pomegranate extract group consumed 100 ml of pomegranate extract 3 times a week. Data analysis was performed using one-way analysis of variance (ANOVA) with LSD post hoc test and paired t-test at a significance level of P ≤ 0.05.  
Results: The results showed that the rate of muscle hypertrophy (hip muscle circumference) increased significantly after 8 weeks of strength training and strength training + pomegranate extract, which was higher in the strength training + pomegranate extract group (p = 0/001). The maximum strength in lower body muscles increased significantly after eight weeks in both groups of strength training and strength training + pomegranate extract (P = 0/001). Body fat percentage of subjects was also decreased significantly in the strength training + pomegranate extract group (P = 0/03). On the other hand, no significant change was observed in resting metabolism of the study groups (P > 0/05).
Conclusion: According to the results of the present study, it seems that the combination of strength training with pomegranate extract increases it’s effect on strength and muscle hypertrophy.
