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

本研究的目的在于：1）探讨主成分分析法所得到的第一主成分是否可以作为生物体适能年龄的评估方程式，（2）应用主成分模型建立了两种预测生物学年龄和体能年龄的方程，并对30名生理学年龄和体能年龄的数据进行了因子分析参数和实足年龄，这是管理的样本462名男性，并显示31个参数分为12个因素。在这12个因素中，第一个因素与31个参数中的20个参数显著相关，并且与年龄的相关性特别高（R=0.79）。因此，第一个因素被解释为主要的老化因素，在大多数或所有身体系统中似乎非常相似。根据上述统计模型，建立了两种生物学年龄评价方程和一种体质年龄评价方程。第一个评估生物年龄的方程由11个生理参数组成，这些参数被应用于83名健康女性（30-72岁）。第二个方程由65名健康女性（20-64岁）的9项生理参数组成。对348名20-70岁健康女性进行了7项运动适能测试参数的测查，并建立了一个评价运动适能年龄的方程。

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).
