在选择适当的缓冲区大小来研究环境对身体活动的影响时，研究受到对老年人积极旅行距离的了解不足的阻碍。本研究的目的是深入了解旅行的步行和骑自行车在不同的缓冲区大小使用GPS的措施。数据来自老年人及其邻居研究（Spijkenisse，荷兰（2011-2012））。行程长度和运输方式来自GPS数据（N=120;总行程数= 337）。距离衰减函数拟合，以估计常用的缓冲区大小内的杂货店的行程的百分比。50%的步行旅行距离至少为729米;骑自行车的旅行距离为1665米。75岁以下的老年人和有功能限制的人比75岁以上的人和没有功能限制的人步行和骑自行车的距离短。男性骑自行车的距离比女性短。距离衰减函数可以帮助选择适当的缓冲器大小，其可以针对个体特性进行定制。(C)2014爱思唯尔有限公司版权所有。
In choosing appropriate buffer sizes to study environmental influences on physical activity, studies are hampered by insufficient insight into the distance elderly travel actively. This study aims at getting insight into the number of trips walked and cycled within various buffer sizes using GPS measures. Data were obtained from the Elderly And their Neighborhood study (Spijkenisse, the Netherlands (2011-2012)). Trip length and mode of transport were derived from the GPS data (N=120; total number of trips = 337). Distance decay functions were fitted to estimate the percentage of trips to grocery stores within commonly used buffer sizes. Fifty percent of the trips walked had a distance of at least 729 m; for trips cycled this was 1665 m. Elderly aged under 75 years and those with functional limitations walked and cycled shorter distances than those over 75 years and those without functional limitations. Males cycled shorter distances than females. Distance decay functions may aid the selection of appropriate buffer sizes, which may be tailored to individual characteristics. (C) 2014 Elsevier Ltd.
