ABSTRACT
Background and Aim: The main purpose of this study was to compare the effect of three methods of combined training [strength and endurance] on serum adiponectin levels and insulin resistance in overweight elderly women
Material and Methods: In this semi-experimental study, 40 elderly women [mean agepf 60.34 +/- 0.82 years, mean height: 155 +/- 0.01 cm, and mean weight: 71.72 +/- 1.89 kg] were enrolled using purposeful method and then randomly assigned to four groups: strength + endurance [n=10], endurance + strength [n=9], circulation combined [n=12], and control [n=9] groups. Serum adiponectin levels and insulin resistance index were measured before, and 48 hours after the last training session. Training programs were implemented three days a week for eight weeks. Paired t - test was used for evaluation of differences within each group and one-way ANOVA to compare the groups with one another
Results: After eight weeks of combined training, all three experimental groups showed significant reduction in weight, body mass index [BMI], body fat percentage, and glucose [P and le0.05]. Significant differences were found in weight [p=0.017] and BMI [p=0.023] between the 4 groups, but no significant differences were found in adiponectin and insulin resistance [p>0.05]
Conclusion: According to the results of this study, despite positive changes in body composition and body fat percentage, none of the three methods of combined training caused a significant change in serum adiponectin levels and insulin resistance in the overweight elderly women
