Accumulating evidence indicates that obesity and sedentary lifestyle is associated with low cardiovascular fitness. This study was conducted 1), to evaluate the effect of aerobic exercise training on maximal oxygen uptake (VO2max) as a major marker of cardiovascular fitness in obese men 2), to determine the relationship between VO2max with anthropometrical markers follow up exercise training in studied subjects. For this purpose, thirty sedentary middle-aged obese men were divided into exercise (aerobic training) and control (without exercise training) groups by randomly. Anthropometrical markers such ad body mass index (BMI), abdominal circumference, body fat percentage and visceral fat and VO2max were measured before and after an aerobic exercise program (3 months, 3 time/weekly) in exercise and groups. At baseline, there were no differences in VO2max and anthropometrical indexes between the two groups. VO2max improved significantly after aerobic training when compared with baseline levels. Aerobic training also led to significant decrease in anthropometrical markers in exercise group. VO2max was negative significantly correlated with BMI, visceral fat and abdominal circumference and other anthropometrical markers after aerobic program in exercise group. All variables remained no change in control group. Based on this data, we conclude that decreased anthropometrical markers by aerobic training program are associated with an improvement in cardiorespiratory fitness in obese males.
