Relationships of academic achievement (government tests) with physical fitness (multistage run), physical activity (pedometers) and percent body fat (dual emission X-ray absorptiometry) were examined at both the aggregate school level and the individual child level using data collected from 757 children in 29 elementary schools. Statistical adjustments included gender, grade and socioeconomic status. Between-school relationships of the academic scores with fitness and physical activity were strong and positive, with some evidence of (negative) relationships with percent body fat. The between-child relationships were weaker, and nonexistent with percent body fat. Stronger between-school than between-child relationships favor the argument that variation in school cultures, characterized by concurrent attention to fitness and academic achievement, might play a more dominant role in explaining these relationships than any direct effect of fitness on academic achievement.
利用从29所小学的757名儿童收集的数据，在学校总体层面和个体儿童层面上，研究了学业成绩（政府测试）与身体素质（多级跑）、身体活动（计步器）以及体脂百分比（双能X线吸收法）之间的关系。统计调整包括性别、年级和社会经济地位。学业成绩与身体素质和身体活动之间的校际关系很强且呈正相关，有一些证据表明与体脂百分比存在（负）相关关系。儿童个体之间的关系较弱，与体脂百分比不存在相关关系。校际关系比儿童个体之间的关系更强，这支持了这样一种观点，即学校文化的差异（其特点是同时关注身体素质和学业成绩）在解释这些关系方面可能比身体素质对学业成绩的任何直接影响发挥更主要的作用。
