The purpose of this study was to investigate whether adult men and women who are in a state of high physical fitness are in a good health state biologically, in terms of biological and physical fitness ages as estimated by statistical means. Biological and fitness ages were estimated from the data related to physiological functions and fitness tests, respectively by a principal component model. The correlation coefficients between biological and fitness ages were 0.72 (p < 0.01, for men) and 0.70 (p < 0.01), respectively. Therefore, those who were in a state of high physical fitness were considered to be in good biological condition. Addition studies with known ischemic heart disease patients and those with high coronary heart disease risk factors indicated that the group with high risk factors showed in average estimated biological age was nearly 5 years old than those without any risk factors.
