Development and standardization of theoretical formulas for the assessment of physical fitness age in middle-aged and old women.

本研究的目的是：1)研究主成分分析得到的第一主成分是否可以作为评价一个人的生物和身体健康年龄的方程；2)应用主成分模型建立两种预测一个人的生物和身体健康年龄的方程。对462名男性样本的30个生理参数和年龄进行因子分析，结果表明，31个参数被归类为12个因素。在这12个因子中，第一个因子与31个参数中的20个显著相关，且与年龄的相关性尤其显著(R=0.79)。因此，第一个因素被解释为主要的衰老因素，似乎在大多数或所有身体系统中非常相似。在上述统计模型的基础上，建立了两种生物年龄评价方程和一种身体适龄评价方程。评估生物年龄的第一个方程由11个生理参数组成，83名健康女性(年龄30-72岁)接受了这些参数的测试。第二个方程由9个生理参数组成，用于65名健康女性(20岁-)。对348名20~70岁的健康女性进行了7项运动素质测试，建立了评价身体健康年龄的方程式。

The purpose of the present study are to 1) investigate whether the 1st principal component obtained from principal component analysis can be used as an equation for assessing one's biological and physical fitness ages, and to 2) develop two kinds of equations for predicting one's biological and physical fitness ages through the application of principal component model.A factor analysis was applied to the data for 30 physiological parameters and chronological age which were administered to a sample of 462 males, and revealed that the 31 parameters were grouped into 12 factors. Of these 12 factors, the 1st factor was loaded significantly with 20 of the 31 parameters and showed especially a high correlation with age (R=0.79). Thus, the 1st factor was interpreted as a primary aging factor which appeared to be very similar in most or all body systems. From this result, it is fully expected that the score of the 1st principal component from principal component analysis can be used as an unitary index related to the aging process of various physiological functions.Based on the above-mentioned statistical model, two kinds of equations for the assessment of one's biological ages and an equation for the assessment one's physical fitness age were developed. The first equation for the assessment of biological age consisted of the 11 physiological parameters which were administered to 83 healthy women (aged 30-72). The second equation consisted of the 9 physiological parameters which were administered to 65 healthy women (aged 20-64). An equation for the assessment of physical fitness age consisted of the 7 motor fitness test parameters which were administered to 348 healthy women (aged 20-70).
