Purpose: The purpose of this study was to examine the impact of a before-school physical activity program on middle school students' social and emotional learning (SEL) and their energy levels. Method: A total of 171 students (67 in program group; 104 in control group) participated in the study from fall 2019 to spring 2022. The physical education teacher implemented the program 3 days per week, for 8 weeks. The students completed a 17-item SEL assessment before and after the program. The program group also reported their energy levels using an energy meter at each session. Results: Students' SEL in program group improved by 14% (p < 0.001) at the end of the program. Students also reported higher energy levels (p < 0.001) following their participation at each session. Discussion/Conclusion: Schools are encouraged to incorporate before-school physical activity programs to energize the students at the start of the school day and improve their SEL.
