目标。公园是重要的体育活动场所，但很少有研究根据多个用户的人口统计特征来检查公园区域之间的体育活动差异。本研究探讨了不同性别、年龄和种族/民族的公园环境中成人/老年人和儿童/青少年PA强度的差异。2009年7月至8月，在密苏里州堪萨斯城的四个公园中使用了观察社区游戏和娱乐系统（SOPARC）来记录公园用户在特定公园区域内的PA行为。共记录了8855次观测。ANCOVAs比较了不同人口群体在五个最常使用的公园目标区域（成人/老年人和儿童/青少年）的平均能量消耗（EE）。在成人/老年人中，所有子样本在铺砌小径（0.086-0.093 kcal/kg/min）和网球场（0.086-0.089 kcal/kg/min）的EE均高于露天场所、游乐场或野餐亭。在儿童/青少年中，儿童、怀特和所有儿童/青少年亚样本显示，操场上的情感表达（0.088-0.089千卡/公斤/分钟）高于野餐场所。公园规划和设计工作应考虑环境和规划举措，以增加公园区域内的代际PA水平，如游乐场、开放空间和野餐场所。(C) 2012爱思唯尔公司版权所有。
Objective. Parks are important physical activity (PA) settings, but few studies have examined PA differences between park areas according to multiple user demographic characteristics. This study explored variations in adult/senior and child/teen PA intensity across park settings by gender, age, and race/ethnicity.Methods. In July-August 2009, the System for Observing Play and Recreation in Communities (SOPARC) was used in four parks in Kansas City, Missouri to record park users' PA behavior within specific park areas. A total of 8855 observations were recorded. ANCOVAs compared mean energy expenditure (EE) for various demographic groups across the five most-used park target areas for adults/seniors and children/teens.Results. Among adults/seniors, all sub-samples exhibited higher EE on paved trails (0.086-0.093 kcal/kg/min) and tennis courts (0.086-0.089 kcal/kg/min), than in open spaces, playgrounds, or picnic shelters. Among children/teens, the child, White, and all child/teen sub-samples showed greater EE on playgrounds (0.088-0.089 kcal/kg/min) than in picnic shelters.Conclusion. Park planning and design efforts should consider environmental and programming initiatives to increase intergenerational PA levels within park areas such as playgrounds, open spaces, and picnic shelters.
