Abstract |
The purpose of the present study was to examine the relationship between endurance fitness level and the prevalence of hypertension, diabetes mellitus and dyslipidemia in Japanese men. The subjects w...ere 906 Japanese men aged 19-60 years. Maximal oxygen uptake (VO2max) was predicted using a cycle ergometer as an index of endurance fitness. Subjects were classified into four groups; G1 (VO2max<35ml/kg/min), G2 (35 ≦VO2max<40), G3 (40≦VO2max<45), and G4 (VO2max≧45). Hypertension was defined as systolic blood pressure≧140 mmHg and/or diastolic blood pressure≧90mmHg. Diabetes mellitus was defined as fasting glucose level≧126mg/dl. Dyslipidemia was defined as total cholesterol≧220mg/dl and/or triglyceride≧150 mg/dl and/or HDL-cholesterol<40ng/dl. Smoking and the alcohol consumption data were obtained from questionnaires. The association between endurance fitness level and the prevalence of chronic disease was analyzed using a logistic regression model adjusted for age, BMI, smoking, and alcohol consumption. The multivariate-adjusted odds ratio (OR) of hypertension was 0.55 (95% CI, 0.30-0.99) for G3 and 0.50 (0.30-0.86) for G4 compared with G1. The multivariate-adjusted OR of dyslipidemia was 0.56 (0.38-0.93) for G2 and 0.53 (0.35-0.78) for G4 compared with G1. But we failed to demonstrate any relationship between endurance fitness level and prevalence of diabetes. These results suggest that the moderate endurance fitness levels were associated with a low prevalence of hypertension and dyslipidemia independent of age, BMI, smoking, and alcohol consumption.show more
