The relationship between daily physical activity levels and cardiometabolic parameters in elderly postmenopausal women

Abstractbackground: cardio-metabolic diseases, including diabetes, hypertension, dyslipidemia, and coronary heart disease (chd). specially, greater physical activity is known to prevent and reduce the risk of many cardio-metabolic diseases. walking is used under lifestyle conditions as a movement current pattern, especially in several social jobs. the aim of present study is to evaluate the relationship step per day with cardio-metabolic risk factors , and the effects of physical activity volume on this variables.methods: daily step volumes voluntarily were measured in the health postmenopausal women(n=40) by the electronic pedometer. subjects (aged 55.9 ±4.6) divided by as active group(ag =20) and sedentary group(sg=20). cardio-metabolic variables analyzed with the standards methods. results: daily step averages in the ag(8022±2659 step/day) significantly was higher than sg (3450±913 step/day) (p<0.001). ). there was a significant difference in body composition variables (bmi,%bf, whr) among 2 groups and significant inverse correlations were found between activity and body composition variables in women(p<0.05). the significant inverse correlations was found between activity and hdl-c(r=0.34). the other correlations (ldl-c,tc, tg, homa-ir,insulin, blood sugar) with steps per day were not significant(p>0.05). conclusion: in conclusion , in view of regular physical activity, increasing daily step volume may be associated with decrease risk factors for chronic disease (increasing hdl-c) and obesity(bmi,%bf, whr) for a 2 years period in the adult women. it seems that increasing steps per day (at least 8000 step/day) were not associated with changes in appetite hormones concentrations.
