调查60-64岁的久坐时间、中等强度至高强度体力活动（MVPA）和体力活动能量消耗（PAEE）与体能指标的相关性。作为2006-2010年进行的详细临床评估的一部分，在英格兰、苏格兰和威尔士MRC国家健康与发展调查的1727名参与者中，使用单独校准的心率和运动感知组合评估了久坐、MVPA和PAEE的时间。多变量线性回归模型被用来检查这些行为变量的标准化措施与握力，椅子上升和定时上升和去（TUG）的速度和站立平衡时间之间的横截面关联。MVPA时间越长，体能水平越高; MVPA时间每增加1个标准差，每个能力指标的校正平均差异为：握力（0.477 kg，95%置信区间（CI）：0.015 - 0.939），椅子上升速度（0.429 stand/min，95% CI：0.093至0.764）、站立平衡时间（0.028 s，95% CI：0.003至0.053）和拖船速度（0.019 m/s，95% CI：0.011至0.026）。相比之下，久坐时间与较低的握力（-0.540 kg，95% CI：-1.013至-0.066）和TUG速度（-0.011 m/s，95% CI：-0.019至-0.004）相关。PAEE的相关性与MVPA相似。较高水平的MVPA和整体身体活动（PAEE）与较高水平的身体能力相关，而久坐不动的时间与较低水平的能力相关。未来对老年人的干预研究应侧重于促进体力活动和减少久坐时间。
To investigate the associations of time spent sedentary, in moderate-to-vigorous-intensity physical activity (MVPA) and physical activity energy expenditure (PAEE) with physical capability measures at age 60-64 years. Time spent sedentary and in MVPA and, PAEE were assessed using individually calibrated combined heart rate and movement sensing among 1727 participants from the MRC National Survey of Health and Development in England, Scotland and Wales as part of a detailed clinical assessment undertaken in 2006-2010. Multivariable linear regression models were used to examine the cross-sectional associations between standardised measures of each of these behavioural variables with grip strength, chair rise and timed up-&-go (TUG) speed and standing balance time. Greater time spent in MVPA was associated with higher levels of physical capability; adjusted mean differences in each capability measure per 1standard deviation increase in MVPA time were: grip strength (0.477 kg, 95% confidence interval (CI): 0.015 to 0.939), chair rise speed (0.429 stands/min, 95% CI: 0.093 to 0.764), standing balance time (0.028 s, 95% CI: 0.003 to 0.053) and TUG speed (0.019 m/s, 95% CI: 0.011 to 0.026). In contrast, time spent sedentary was associated with lower grip strength (-0.540 kg, 95% CI: -1.013 to -0.066) and TUG speed (-0.011 m/s, 95% CI: -0.019 to -0.004). Associations for PAEE were similar to those for MVPA. Higher levels of MVPA and overall physical activity (PAEE) are associated with greater levels of physical capability whereas time spent sedentary is associated with lower levels of capability. Future intervention studies in older adults should focus on both the promotion of physical activity and reduction in time spent sedentary.
