Students' (n=1,041) physical activity choices were assessed during the fourth and sixth grades for weekdays, weekends, and summer vacations. Activities were summarized for boys and girls by intensity, individual versus team, and for selected classes. Boys performed more team activities and reported more overall physical activity. Boys and girls decreased their participation in individual physical activities. Students decreased in total energy expended for all time periods. Decreasing activity level and selection of fewer individual activities make lifetime exercise unlikely. Results suggest that children become less active than recommended for health promotion before completing elementary school.
