设计：一项为期3年的前瞻性研究，使用纵向老龄化研究的数据。研究对象：荷兰。研究对象：2,109名年龄在55岁至85岁之间的男性和女性。测量：使用有效的、由采访者管理的问卷来测量总的体力活动(以每天的小时数和卡路里数表示)和运动参与度。通过两个计时测试来评估活动能力：6米步行和重复的椅子站立。结果：45.6%的样本的活动能力下降。在基线时，平均花费在总体力活动上的+/-标准差为3.0+/-2.1小时/天或719+/-543千卡/天，56.6%的样本参与了体育运动。运动参与度和总体体力活动、步行或家庭活动水平较高与较小的行动能力下降有关。三年后，总的体力活动减少，只有53.4%的报告运动基线的人继续这样做。随着时间的推移，持续的体力活动与活动能力的下降幅度最小有关。对于患有和没有慢性病的患者，观察到的相关性是相似的(P>；0.3)。在调整了包括人口统计和生活方式变量、抑郁和认知状态在内的潜在混杂因素后，结论没有改变。结论：体力活动，特别是经常活动的生活方式，可能会减缓行动能力的下降。观察到运动和非运动活动的有益效果，与慢性病的存在无关。
OBJECTIVES: This study examined the association of (change in) physical activity and decline in mobility performance in older men and women.DESIGN: A 3-year prospective study using data of the Longitudinal Aging Study.SETTING: Netherlands.PARTICIPANTS: Two thousand one hundred nine men and women aged 55 to 85.MEASUREMENTS: Total physical activity (expressed as hours per day and kilocalories per day) and sports participation were measured using a validated, interviewer-administered questionnaire. Mobility performance was assessed using two timed tests: 6-meter walk and repeated chair stands.RESULTS: Mobility performance declined for 45.6% of the sample. At baseline, the mean time +/- standard deviation spent on total physical activity was 3.0 +/- 2.1 h/d or 719 +/- 543 kcal/d, and 56.6% of the sample participated in sports. Sports participation and a higher level of total physical activity, walking, or household activity were associated with a smaller mobility decline. After 3 years, total physical activity declined, and only 53.4% of those reporting sports at baseline continued doing so. Continuation of physical activity over time was associated with the smallest decline in mobility. The observed associations were similar for those with and without chronic disease (P > 0.3). The conclusions did not change after adjustment for potential confounders, including demographic and lifestyle variables, depression, and cognitive status.CONCLUSIONS: Physical activity, and especially a regularly active lifestyle, may slow the decline in mobility performance. A beneficial effect was observed for sports and nonsports activities, independent of the presence of chronic disease.
