Abstract Objectives: To investigate the effects of cardiorespiratory fitness and obesity on risk factors for metabolic syndrome in adult Japanese females. Materials and Methods: A total of 1,089 females (n = 296 subjects in their 30's, 518 subjects in their 40's and 276 subjects in their 50's) who underwent medical checkups and physical fitness measurements at a health checkup facility between April 2007 and July 2013 were divided into normal-weight (body mass index, BMI </= 24.9) and obese (BMI >/= 25) groups for each age category. The normal-weight subjects in each age category were subsequently divided into four groups according to the maximum oxygen consumption. The systolic and diastolic blood pressure levels and HDL-cholesterol, triacylglycerol and glucose blood concentrations were compared between the groups. Results: Significant differences were observed between the highest quartile group among the normal and obese females, with the exception of the diastolic blood pressure values and glucose concentrations in the subjects in their 30's, with superior values noted in the highest quartile normal-weight group versus the obese group. In contrast, no significant differences were found between the lowest quartile group among the normal and obese females, with the exception of the HDL-cholesterol concentrations in the subjects in their 30's and the systolic and diastolic blood pressure values in the subjects in their 40's. Conclusions: Low cardiorespiratory fitness appears to be associated with a higher risk of metabolic syndrome, independent of obesity, in adult Japanese females.
