To examine the relationship between habitual physical activity and components of health-related physical fitness in children.
Cross-sectional survey with correlational analysis.
Seven public elementary schools in a suburban southern California city.
Five hundred twenty-eight healthy fourth-grade children (274 boys and 254 girls), 85% of whom were non-Hispanic whites. Ninety-eight percent of eligible students participated.
None.
MEASUREMENTS/MAIN RESULTS: Results of six measures of physical activity in children (monitoring by accelerometer, parent report, and child self-reports of weekday activity, weekend activity, and summer involvement in activity classes and youth sports) were combined in a physical activity index. This index of habitual physical activity was examined in relation to measures of five components of health-related fitness: the mile run, skin-fold tests, pull-ups, sit-ups, and the sit-and-reach test. The physical activity index was significantly associated with all five fitness components. The canonical correlation was .29.
Active children appear to engage in a sufficient variety of activities to enhance multiple components of health-related fitness.
探讨儿童习惯性身体活动与健康相关身体素质各组成部分之间的关系。
采用相关分析的横断面调查。
南加州郊区一个城市的七所公立小学。
528名健康的四年级儿童（274名男孩和254名女孩），其中85%为非西班牙裔白人。98%符合条件的学生参与了调查。
无。
测量/主要结果：通过加速度计监测、家长报告以及儿童对平日活动、周末活动和暑期参加活动课程及青少年体育活动的自我报告，综合得出六项儿童身体活动测量结果，形成身体活动指数。该习惯性身体活动指数与健康相关身体素质五个组成部分的测量指标进行了相关性分析，这五个指标分别为：一英里跑、皮褶厚度测试、引体向上、仰卧起坐和坐位体前屈测试。身体活动指数与所有五个身体素质组成部分均显著相关。典型相关系数为0.29。
活跃的儿童似乎参与了足够多样的活动，以增强健康相关身体素质的多个组成部分。
