目的：本研究旨在建構功能性體適能年齡公式。方法：採用教育部體育署「103年樂活體能檢測專案」的15,712位女性資料，採隨機抽樣70%（10,998位）進行主成分分析以建構功能性體適能年齡公式，30%（4,714位）進行覆核效度考驗。結果：功能性體適能年齡公式為（-6.20 × 體適能得分）+（0.58 × 實際年齡）+ 30.56，實際年齡和功能性體適能年齡之相關係數為r =.66。覆核效度考驗發現實際年齡和功能性體適能年齡差的平均值為0.10 ± 8.09歲，兩年齡間的相關為r = .68。結論：故推測本研究得到之公式可作為評估健康度的指標，提供健康指導員或臨床醫師等，在判別相同年齡但不同個體之功能性體適能狀況使用。

Purpose: The purpose of this study was to estimate the functional fitness age formula of older female in Taiwan using principal component analysis. Methods: There were totally 15,712 female fitness data from senior fitness test database of sport administration, ministry of education. The data were divided into two groups for modeling (n = 10,998) and for cross-validation of them (n = 4,714). Results: Functional fitness age equation is (-6.20 × fitness score) + (0.58 × calendar age) + 30.46. The correlation coefficient between calendar age and functional fitness age is .66. Cross-validation data yields similar result applying the same formula. The correlation coefficient between calendar age and physical age is .68. Conclusion: The functional fitness age offers researchers, personal trainer or physician an alternative method to access the health of a person beside the same age.
