Increased waist circumference has shown to be more strongly associated with cardiovascular disease risk factors. The purpose of this study is to investigate the association between exercise capacity and cardiovascular risk factors among obese types in adult men. The subjects of this study were a total fifty-four obese persons and obesity criteria is body mass index (BMI)¡Ã25 kg/m2. Diagnostic criteria for obesity was defined as a waist circumference of ¡Ã90 cm. The BMI in the obese subjects, as judged by the presence or absence of abdominal obesity, were classified into two groups (non-AO: without abdominal obesity group, AO: with abdominal obesity group). AO presented lower total exercise time, metabolic equivalents (METs) than Non-AO. AO showed slow HRR (heart rate recovery) response. HRR was negative correlated with BMI, body fat mass, waist circumference. AO had a high heart rate and a low cardiac output in submaximal exercise stage 1¡2. In conclusion, AO¡¯s (with abdominal obesity groups) total exercise time, METs and HRR are lower than Non-AO. HRR is related with BMI, body fat mass and waist circumference.
