Methods: Twenty postmenopausal women were randomly assigned to a resistance training protocol (n=10, 53.40±3.95 years, 64.58±9.22 kg) or a control group (n=10, 53.0±5.7 years64.03±5.03 kg). In the resistance training protocol, ten exercises were performed, with 3×8, 10 maximal repetitions three times per week, and the load was increased every week. Two- way analysis of variance was used to evaluate specific metabolic syndrome Z-score, high density lipoprotein cholesterol, fasting blood glucose, triglycerides, waist circumference, blood pressure strength, and body composition. The level of statistical significance was set at P=0.05.

Results: The main results demonstrated a significant decrease of metabolic syndrome Z-score when the postmenopausal women performed resistance training (P=0.0162). Moreover, we observed decreases in fasting blood glucose for the resistance training group (P=0.001), and also significant improvements in lean body mass (P=0.042, 2.46%), reduction of body fat percentage (P=0.001, -6.75%) and noticeable increases in muscle strength after resistance training to leg press (P=0.004, 41.29%) and bench press (P=0.0001, 27.23%).

Conclusion: It was concluded that resistance training performed three times a week may reduce the metabolic syndrome Z-score with concomitant decreases in fasting blood glucose improvements in body composition, and muscle strength in postmenopausal women.
