The relationship between obesity indexes with vascular endothelial function after a period of circuit combined training in older women
Journal Title: International Journal of Applied Exercise Physiology - Year 2016, Vol 5, Issue 4
Abstract
Obesity and its indices including BMI, WHR, and fat% are related with cardiovascular diseases and also involved in endothelial dysfunction and endothelium-dependent dilation. However, the correlations of these indices with endothelial function, especially in older women remain very poorly defined. The aim of this study was investigation on the relationship between some of the obesity indices with vascular endothelial function after a period of combined circuit training in older women. Subjects were 24 healthy and enable to do physical activity old women from Shahrekord (Chaharmahal and Bakhtiary province, Iran) retirement home (age=74.22±4.46). Subjects were randomly divided to two groups including experimental (n=12) and control (n=12). Obesity indices (Fat%, WHR, and BMI) and endothelium-dependent dilation of brachial artery were measured in both experimental and control groups, just before the training protocol starting. Then Experimental group was participated in 12 week (three times a week) combined circuit training program. All of mentioned measurements repeated at the end of 12th week. The obtained results showed that 12 week combined circuit training program has significant effect on reduction of old women obesity Indices (P≤0.001). Also, a diverse relationship was observed between age, BMI, WHR and Fat% with FMD (flow-mediated dilation) in experimental (BMI: P=0.45, r=-0.24, WHR: p=0.10, r=-0.49, Fat%: p=0.69,r=-0.12, age=0.87, r=-0.05) and control groups (BMI: P=0.18, r=-0.41, WHR: p=0.62, r=-0.15, Fat%: p=0.75,r=-0.1, age=0.757, r=-0.1). It seems that use of 12 week combined circuit training has positive effects on obesity indices and improvement of endothelial function in Iranian old women. Anthropometric measures of obesity indices may help refine estimations of endothelial health and atherosclerotic state. BMI and WHR were most consistently associated with endothelial dysfunction. Thus, using regular training through the reduction in obesity indices could improve endothelial function and body composition and eventually reduce atherosclerosis and CVD occurrence in older women.
