Understanding children's physical activity (PA) patterns and the factors that may influence PA are important for developing interventions within this population. One hundred and ten children aged 9-10 years from 8 schools had their PA patterns assessed over 7 days. Physiological and self-report data were also collected. Multilevel analyses revealed that cardiorespiratory fitness was a consistent, significant and positive predictor of weekday and weekend PA, while the availability of home sedentary activities was a significant but negative predictor of PA. Since a range of variables were associated with PA levels, intervention developers should be cognizant of variables that may influence children's activity.
了解儿童的身体活动（PA）模式以及可能影响身体活动的因素，对于在这一人群中开展干预措施非常重要。来自8所学校的110名9至10岁儿童的身体活动模式在7天内得到评估。同时还收集了生理和自我报告数据。多层次分析显示，心肺适能是工作日和周末身体活动的一个持续、显著且积极的预测因素，而家庭久坐活动的可获得性是身体活动的一个显著但消极的预测因素。由于一系列变量与身体活动水平相关，干预措施开发者应认识到可能影响儿童活动的变量。
