Field Estimation of Maximum Oxygen Consumption and its Relationship with Central Obesity in Women of Different Age Groups in Qazvin Provinces, East Azarbaijan and Hamedan

Central obesity is a serious risk factor for cardiovascular diseasesand has an inverse relationship with Vo2max. This study had tried to evaluate Vo2max using Bruce protocol, Rockport, Pedometer and International Physical Activity Questionnaire (IPAQ) in women of different age groups in Qazvin, East Azarbaijan and Hamadan provinces, and identify its relationship with central obesity indices (WHtR, WHR, SBSI and BAI).

Using Morgan method women aged 20-60 years were selected by cluster sampling from the centers of the provinces, respectively, and anthropometric variables, rackport test,IPAQ questionnaire completion, pedometer connection for 7 days, and finally, the Bruce test was performed respectively. Normality of data was assessed by Kolmogorov-Smirnov test and comparison of different age groups with multivariate covariance analysis and Tukey post hoc test. Finally, the relationship between Vo2max and central obesity indices was assessed by using Pearson correlation test.

There was a significant difference between the level of Vo2max in different age groups as well as between the samples three provinces (P=0.001). There was also a significant reverse correlation between the estimation of Vo2max in two indices (WHtR, BAI), but in two indices (WHR, SBSI), in some cases, there was a significant relationship and in some cases wasn't significant.

The decrease in physical activity and subsequent cardiorespiratory fitness led to an increase in central obesity indices at different age ranges, indicating a significant reversal of relationship between Vo2max and central obesity indices.
