主要来自横断面研究的证据表明，体力活动是与老年人身体表现和力量相关的一个潜在的重要可变因素。目前还不清楚身体活动的益处是否会在一生中累积，或者是否存在身体活动更具影响力的敏感时期。研究成年期闲暇时间体育活动与中年期身体表现和力量的关系，并测试体育活动是否有累积效益。使用来自英国医学研究理事会全国健康与发展调查的大约2400名男性和女性的数据，自1946年3月出生以来，休闲时间的身体活动水平与36岁，43岁和53岁时的握力，站立平衡和椅子上升时间的关系进行了前瞻性的自我报告，由护士在53岁时进行评估（1999年），2010年进行了检查。有独立的积极影响，身体活动在所有三个年龄的椅子上升性能，并在43岁和53岁的站立平衡性能，即使在调整协变量。这些结果得到了使用结构化生命过程模型时发现的累积效应证据的支持。在女性中，体力活动和握力不相关，在男性中，只有53岁时的体力活动与握力相关。成年后的身体活动对中年的身体表现有累积的好处。应在成年早期促进增加活动，以确保在以后的生活中保持身体机能。
Evidence, mainly from cross-sectional studies, suggests that physical activity is a potentially important modifiable factor associated with physical performance and strength in older age. It is unclear whether the benefits of physical activity accumulate across life or whether there are sensitive periods when physical activity is more influential. To examine the associations of leisure-time physical activity across adulthood with physical performance and strength in midlife, and to test whether there are cumulative benefits of physical activity. Using data on approximately 2400 men and women from the UK Medical Research Council National Survey of Health and Development, followed up since birth in March 1946, the associations of physical activity levels during leisure time self-reported prospectively at ages 36, 43, and 53 years with grip strength, standing balance, and chair rise times, assessed by nurses at age 53 years (in 1999), were examined in 2010. There were independent positive effects of physical activity at all three ages on chair rise performance, and at ages 43 and 53 years on standing balance performance, even after adjusting for covariates. These results were supported by evidence of cumulative effects found when using structured life course models. Physical activity and grip strength were not associated in women and, in men, only physical activity at age 53 years was associated with grip strength. There are cumulative benefits of physical activity across adulthood on physical performance in midlife. Increased activity should be promoted early in adulthood to ensure the maintenance of physical performance in later life.
