研究了221名健康成年男性（年龄20-85岁）的人群，以确定那些经常锻炼的人是否处于良好的生物学状态，以及那些处于高体能状态的人是否处于良好的生物学状态，在生理年龄（PA）和体能年龄（FA）方面，通过主成分分析估计。分别采用17项生理机能测试和5项体能测试来估计PA和FA。这项研究的结果表明，那些在20至79岁的所有年龄组中保持高体能的人有保持相对较低的PA（生理上更年轻）的趋势。训练组的平均PA和FA分别比未训练组年轻4.7和7.3岁。此外，训练组PA随年龄增长的回归线斜率较非训练组平缓。这些结果表明，那些处于高身体素质状态的人保持着相对良好的生理状态，定期的体育锻炼可以延缓通常随着衰老而出现的生理变化，从而可以延长寿命。
A population of 221 healthy adult men (aged 20-85 years) was studied to determine whether those who exercised regularly were in good biological condition, and also whether those who were in a state of high physical fitness were in a good state biologically, in terms of physiological age (PA) and physical fitness age (FA) as estimated by principal component analysis. A group of 17 physiological function tests and 5 physical fitness tests were employed to estimate PA and FA, respectively. The results of this study indicated that those who maintained high physical fitness at all age decade groups from 20 to 79 years had a trend towards maintaining a relatively lower PA (physiologically younger). Mean PA and FA of the trained group were younger by 4.7 and 7.3 years, respectively than those of the untrained group. In addition, the slope of regression line of PA on chronological age was more gentle in the trained group than that in the untrained group. These results would suggest that those who are in a state of high physical fitness maintain a relatively good physiological condition, and that regular physical exercise may delay physiological changes normally seen with aging, and consequently may increase the life span.
