This study examined the effects of an eight week classroom-based physical activity program (Energizers) on the moods of third and fourth-grade students. One third and one fourth grade class participated in the teacher-led Energizers program, while the other third and fourth grade classes served as a control group. Students reported their mood at baseline, four weeks, and at eight weeks. There was no significant interaction between group membership and changes in positive or negative mood. However, girls were found to have higher long-term positive mood scores and lower long-term negative mood scores compared to boys. There was also a main effect of time on long-term positive mood for both the Energizers group and the control group. Because changes were seen in both groups, the effect of time cannot be attributed to participation in the Energizers group.
