This study examined the association of (change in) physical activity and decline in mobility performance in older men and women.
A 3-year prospective study using data of the Longitudinal Aging Study.
Netherlands.
Two thousand one hundred nine men and women aged 55 to 85.
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.
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.
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.
本研究调查了老年男性和女性身体活动（的变化）与运动能力下降之间的关联。
一项为期3年的前瞻性研究，使用纵向老龄化研究的数据。
荷兰。
2109名年龄在55至85岁之间的男性和女性。
使用经过验证的、由访谈员管理的问卷测量总身体活动量（以每天小时数和每天千卡数表示）以及体育活动参与情况。使用两项计时测试评估运动能力：6米步行和重复起坐测试。
45.6%的样本运动能力下降。在基线时，总身体活动的平均时间±标准差为3.0±2.1小时/天或719±543千卡/天，56.6%的样本参与体育活动。体育活动参与以及较高水平的总身体活动、步行或家务活动与较小的运动能力下降相关。3年后，总身体活动量下降，只有53.4%在基线时报告参与体育活动的人继续如此。随着时间的推移持续进行身体活动与最小的运动能力下降相关。对于患有和未患有慢性病的人，观察到的关联相似（P>0.3）。在对潜在混杂因素进行调整后，包括人口统计学和生活方式变量、抑郁和认知状态，结论没有改变。
身体活动，尤其是规律的积极生活方式，可能会减缓运动能力的下降。观察到体育活动和非体育活动都有有益效果，且与是否存在慢性病无关。
