L.汤普森客观测量的身体活动在不同的样本老年城市英国成年人。医学科学体育锻炼：第43卷，第4期，第100页。647-654，2011。背景：老年人的身体活动（PA）有许多健康和社会效益，但对他们的活动模式知之甚少。目的：本研究的目的是客观评估老年人的PA模式以及与PA相关的生活方式和人口统计因素。研究方法：参与者（N = 230，年龄78.1岁）招募的医疗实践（2007年和2008年之间）完成的旅程日志，并佩戴加速度计7天。分析了平均每日步数、每分钟步数（CPM）、久坐、轻度或中度至剧烈PA（MVPA）的分钟数以及旅行频率（2009年）。结果如下：年轻参与者（年龄= 70-74.9岁）比80岁以上的老年参与者（每天3409.6步）更活跃（P < 0.001）。男性的MVPA分钟数显著高于女性（P = 0.035）（23.1 vs 13.8 min MVPA/天）。正常体重组（每天5368.9步）比超重组（每天4532.7步）和肥胖组（每天3251.4步）更活跃（P < 0.05）。那些进行多次旅行的人（每周911.6次旅行）比那些很少旅行的人（每天5838.2步）更活跃（P < 0.001）。

Sports Exerc., Vol. 43, No. 4, pp. 647-654, 2011. Background: There are many health and social benefits of physical activity (PA) for older adults, but little is known about their activity patterns. Purpose: The purpose of this study was to objectively assess the PA patterns of older adults and the lifestyle and demographic factors associated with PA. Methods: Participants (N = 230, aged 78.1 yr) recruited from medical practices (between 2007 and 2008) completed journey logs and wore accelerometers for 7 d. Mean daily steps, counts per minute (CPM), minutes of sedentary, light, or moderate-to-vigorous PA (MVPA), and frequency of journeys were analyzed (in 2009). Results: Younger participants (age = 70-74.9 yr) were significantly (P < 0.001) more active (5660.8 steps per day) than older participants aged 80+ yr (3409.6 steps per day). Men performed significantly (P = 0.035) more minutes MVPA than women (23.1 vs 13.8 min MVPA per day). Normal weight participants were significantly (P < 0.05) more active (5368.9 steps per day) than overweight (4532.7 steps per day) and obese (3251.4 steps per day) groups. Those performing many journeys (911.6 journeys per week) were significantly (P < 0.001) more active (5838.2 steps per day) than those performing few (
