The purpose of the study is to examine the effects of the technology-enhanced quality physical education (Smart-QPE) lessons on physical activity, cardiorespiratory fitness, social emotional learning (SEL) skills, and mental well-being in school students.

Students in 4th-7th grades from 17 elementary and middle schools in Michigan are invited to participate in the study. Students will be assessed with cardiorespiratory fitness, social emotional learning skills, physical activity, and mental well-being at a baseline and the post-intervention tests before and after the Smart-QPE intervention. The Smart-QPE intervention include that PE teachers integrate the Heart Zone Moves System into their teaching quality physical education lesson in October and November, 2025.

• students can stop the aerobic fitness test at the baseline and the post-intervention

Exclusion Criteria:
