评估老年人身体健康的标准化方法尚未建立。在这项研究中，我们开发了一个指数的身体健康年龄（健康年龄分数，FAS）的老年人和调查的基础上估计FAS的性别差异。健康老年人（52名男性，70名女性）在2002年至2008年期间每年进行一次身体素质测试，持续7年。参与者在本研究开始时的年龄范围为60.0至83.0岁。体能测试包括13个项目，以衡量平衡，敏捷性，柔韧性，肌肉力量和耐力。三个标准被用来评估老化的健身标志物：（1）与年龄的显著横截面相关性;（2）随年龄的显著纵向变化与横截面相关性一致;（3）个体差异的显著稳定性。我们开发了一个方程，以评估个人FAS值，使用来自主成分分析的第一个主成分。从13项体能测试中筛选出5项老化的候选体能指标（10米步行时间、功能性伸展、单腿睁眼站立、垂直跳跃和握力）。使用主成分模型从这五个适应性标记预测个体FAS。个体FAS显示年龄相关变化的纵向稳定性较高。通过对个体FAS纵向变化的研究发现，女性的身体素质相对低于男性，但其身体素质老化速度慢于男性。本文的在线版本（doi：10.1007/s11357-011-9225-5）包含补充材料，可供授权用户使用。
A standardized method for assessing the physical fitness of elderly adults has not yet been established. In this study, we developed an index of physical fitness age (fitness age score, FAS) for older Japanese adults and investigated sex differences based on the estimated FAS. Healthy elderly adults (52 men, 70 women) who underwent physical fitness tests once yearly for 7 years between 2002 and 2008 were included in this study. The age of the participants at the beginning of this study ranged from 60.0 to 83.0 years. The physical fitness tests consisted of 13 items to measure balance, agility, flexibility, muscle strength, and endurance. Three criteria were used to evaluate fitness markers of aging: (1) significant cross-sectional correlation with age; (2) significant longitudinal change with age consistent with the cross-sectional correlation; and (3) significant stability of individual differences. We developed an equation to assess individual FAS values using the first principal component derived from principal component analysis. Five candidate fitness markers of aging (10-m walking time, functional reach, one leg stand with eyes open, vertical jump and grip strength) were selected from the 13 physical fitness tests. Individual FAS was predicted from these five fitness markers using a principal component model. Individual FAS showed high longitudinal stability for age-related changes. This investigation of the longitudinal changes of individual FAS revealed that women had relatively lower physical fitness compared with men, but their rate of physical fitness aging was slower than that of men.
