Using the System for Observation of Play and Recreation in Communities (SOPARC), 36 observations were conducted in three parks in Shenzhen, China, to count the physical activity levels of 12297 visitors in 78 target sports grounds. The gender and age differences in the physically active populations were analyzed in formal and informal sports grounds. The results indicate that the physical activity levels of children and adolescents were significantly higher than those of middle-aged and elderly individuals, and males exhibited significantly higher physical activity levels than females. Among formal sports grounds, the physical activity levels on soccer fields, basketball courts, tennis courts, and ping-pong tables were significantly higher than those on other sports grounds. In informal sports grounds, the physical activity levels of children’s non-apparatus activity spaces were the lowest. Some informal sports areas supported a greater variety of physical activities, such as dancing, badminton, soccer, and kite-flying, on park squares and open grassy areas. The research findings can provide environmental strategies for constructing urban parks that are conducive to enhancing physical activity levels.

使用社区游戏与游憩观察系统(SOPARC), 对深圳市的3个公园进行36次观察, 统计78个目标运动场地中12297名游客的体力活动水平, 分析正式和非正式运动场地上体力活动人群的性别和年龄差异。结果表明, 儿童和青少年的体力活动水平显著高于中年人和老年人, 男性的体力活动水平显著高于女性; 正式运动场地中, 足球场、篮球场、网球场和乒乓球场的体力活动水平显著高于其他运动场地; 非正式运动场地中, 儿童无器械活动场地体力活动水平最低; 部分非正式运动场地支持更多样的体力活动, 如园内广场和开放草地支持跳舞、打羽毛球、踢球和放风筝等活动。研究结果可为建设有利于提升体力活动水平的城市公园提供环境策略。
