体力活动是促进健康和幸福的重要因素，特别是对于中年后期的成年人，他们更容易患心血管疾病。在绿色区域进行的体育活动被认为是特别有益的，所以我们研究了晚年中年人在绿色区域是否比在非绿色区域更活跃，以及这是如何受到个人特征和社区绿化水平的影响的。我们使用全球定位系统和加速计数据跟踪了180名中老年(58岁至65岁)成年人，以了解他们是否以及在哪里久坐不动或活动。这些数据与土地利用信息相结合，以获得关于静坐和活动热点的绿色度信息。我们发现，晚年中年人在绿色区域花费的时间比在非绿色区域花的时间更多时，他们的身体活动更多。研究发现，花更多的时间呆在家里和非绿色区域与更多的久坐行为有关。研究发现，花在非绿色区域的时间与男性较多的中等到剧烈的体力活动(MVPA)有关，而与女性较少的MVPA有关。对于受过高等教育的人和生活在绿色社区的人来说，在绿色地区度过的时间与MVPA之间的正相关关系最强。这项研究表明，全球定位系统和加速度计数据的结合使用有助于了解人们在哪里久坐或活动，这可以帮助政策制定者鼓励这个年龄段的活动。
Physical activity is an important facilitator for health and wellbeing, especially for late middle-aged adults, who are more susceptible to cardiovascular diseases. Physical activity performed in green areas is supposed to be particularly beneficial, so we studied whether late middle-aged adults are more active in green areas than in non-green areas and how this is influenced by individual characteristics and the level of neighbourhood greenness. We tracked 180 late middle-aged (58 to 65 years) adults using global positioning system and accelerometer data to know whether and where they were sedentary or active. These data were combined with information on land use to obtain information on the greenness of sedentary and active hotspots. We found that late middle-aged adults are more physically active when spending more time in green areas than in non-green areas. Spending more time at home and in non-green areas was found to be associated with more sedentary behaviour. Time spent in non-green areas was found to be related to more moderate-to-vigorous physical activity (MVPA) for males and to less MVPA for females. The positive association between time spent in green areas and MVPA was the strongest for highly educated people and for those living in a green neighbourhood. This study shows that the combined use of global positioning system and accelerometer data facilitates understanding of where people are sedentary or physically active, which can help policy makers encourage activity in this age cohort.
