THE RECOMMENDED VALUES OF PEAKVO2 FOR FAVORABLE CORONARY RISK FACTOR PROFILES IN JAPANESE FEMALES

Abstract

688 The purpose of this study was to recomend the values of peak VO2 for favorable coronary risk factor profiles in Japanese females. The subjects were 1338 females (ages 30 to 69) who participated in the practical health promotion program at the Tokyo Metro. Health Promotion Ctr. We conducted a medical examination and symptom limited maximal exercise test by ergometer to measure peak VO2 by using an expired gas analyzer. The subjects were divided into 4 groups according to age (ages 30-39, 40-49, 50-59, 60-69). Within each group the subjects were divided into 3 groups according to fitness level (high fitness group, moderate fitness group, and low fitness group) as determined from peak VO2. Finally, all high fitness (n=435), moderate fitness (n=459), and low fitness groups (n=444) were put together. The coronary risk factor profiles of these 3 fitness groups were compared using a one-way ANOVA. The result showed that peak VO2 had a significant favorable effect on coronary risk factor profiles. That is, the subjects in higher fitness groups had lower BMI, %body fat, waist hip ratio, resting blood pressure, and atherosclerosis index, and higher HDL-C compared to those in lower fitness groups. Based on these results, we recommend the following values of peak VO2 for favorable coronary risk factor profiles in Japanese females, (ages 30-39; 31 ml/kg/min, 40-49; 29ml/kg/min, 50-59; 27ml/kg/min, 60-69; 25ml/kg/min). These values of peak VO2 could be useful in making better exercise prescription for Japanese females.
