The Description and Relationship of Cardiorespiratory Function and Body Composition Using Modern Methods in the Isfahan Men and Women

Background & Body mass index and waist circumference do not distinguish subcutaneous fat from visceral fat, which is associated with high levels of cardiovascular dysfunction. The aim of present study was to evaluate the non-invasive respiratory fitness (CRF) in men and women in Isfahan and the possible relationship between the new indicators of abdominal obesity with CRF. In a cross-sectional study on healthy subjects aged 25 to 65 years old in Isfahan, a total of 248 subjects were male and female with a mean age of 37.31 ± 11.39 men and 41.99 ±12.91 men volunteered for the study. Abdominal obesity data includes ABSI, BAI, WHR, cardiopulmonary function (maximum oxygen consumption derived from step by step protocols, rocket and Bruce) and physiological (systolic and diastolic blood pressure) and heart rate were collected and analyzed. The average number of daily steps in men and women was 6172 and 6341, respectively, which was lower in both groups than normal values. In contrast, visceral obesity indices were highly range than those in the same age group. In addition, pedometer Vo2max values were 30.58 ± 10.51, 59.59 ± 91.8 and Vo2max, respectively, were 38.04 ± 14.66, 43.13 ± 13.51, and Vo2max Bruce, and 32/45 ± 4/03 ,44/26 ± 5/51 It was found that almost all body composition indices other than ABSI were negatively related to VO2max by step-by-step protocols and rocket protocols. Our data emphasizes the necessity to develop interventions to improve CRF and to prevent the increase of obesity. Longitudinal research will be required to confirm a potential link of causality between these variables.
