Abstract
Purpose: This study aimed to investigate the effect of 12-week resistance exercise with elastic band on body composition changes and some predisposing factors for endothelial dysfunction in postmenopausal women with sarcopenic obesity.
Methods: 49 Obese elderly women (Age:64.13±3.68; BF%: 44.2±2.56; BMI: 33.1±3.71 and SMI< 27%) volunteered and randomly divided into experimental (n=27) and control (n=22) groups. The subjects of the experimental group have trained resistance exercise with elastic band for 12 weeks; 3d/w. DEXA evaluation for analyzing body mass index and body fat percentage and blood sampling to measuring serum levels of nitric oxide, high density lipoprotein, low density lipoprotein, total cholesterol, and C-Reactive Protein were done 48h pre-training and immediately after post-training.
Results: In the Experimental Group, nitric oxide levels and high density lipoprotein in serum were increased following 12-week resistance exercise with elastic band and low density lipoprotein decreased (p=0.03, p=0.01, p=0.03; respectively); However, there are no changes in body fat percentage, body mass index, total cholesterol, and C-Reactive Protein (p˃0.05).
Conclusion: Findings of this study demonstrated that 12-week resistance exercise with elastic band increased nitric oxide levels and improved blood lipid profile in postmenopausal women with sarcopenic obesity. Therefore, it seems that this training protocol was effective in the management of these predisposing factors of cardiovascular diseases.
