项目摘要

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).

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用作评估一个人的生物和身体健康年龄的方程，以及2）开发两种方程来预测一个人的生物和身体健康年龄。对462名男性样本的30个生理参数和实际年龄数据进行因子分析，发现这31个参数分为12个因素。在这 12 个因素中，第 1 个因素与 31 个参数中的 20 个参数显着相关，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衰老因素，它在大多数或所有身体系统中似乎非常相似。由此结果来看，完全可以预期主成分分析得到的第1主成分得分可以作为与各种生理功能衰老过程相关的统一指标。基于上述统计模型，有两种方程：开发了评估一个人的生物年龄的方法以及评估一个人的身体健康年龄的方程。用于评估生物年龄的第一个方程由 11 项生理参数组成，这些参数适用于 83 名健康女性（30-72 岁）。第二个方程由 9 个生理参数组成，对 65 名健康女性（20-64 岁）进行测量。身体健康年龄评估方程由 7 个运动健康测试参数组成，对 348 名健康女性（20-70 岁）进行了测试。
