A CLASSROOM-BASED PHYSICAL ACTIVITY INTERVENTION FOR ADOLESCENTS: IS THERE A RELATIONSHIP WITH SELF-EFFICACY, PHYSICAL ACTIVITY, AND ON-TASK BEHAVIOR?

Classroom-based physical activity is a newly explored avenue for providing physical activity opportunities to children within the school, but it is one that is showing academic gains in areas such as on-task behavior. The purpose of this study was to explore the impact of pedal desks placed in high school classrooms. Three main objectives were examined: 1) The possible increase in physical activity self-efficacy among high school students in the classroom, 2) the effectiveness of pedal desks on increased physical activity among high school students, and 3) the impact of pedal desks on increasing classroom on-task behavior. Participants included 114 high school students in a traditional high school setting. All of the students were enrolled in two Junior Reserve Officers’ Training Corps (JROTC) teachers’ classrooms. The design was quasi-experimental. Two teachers and their respective classes were randomly assigned to a treatment or wait list control group. The study included a baseline and 2 waves. Researchers gathered demographic information of students, as well as pre- and post-data on self-efficacy and physical activity participation. On-task behavior of students was also collected daily by researchers via momentary time sampling. Results indicated lower self-efficacy confidence for the treatment group compared to the control group at the end of the study after controlling for initial scores. Significance was also found for heart rate. Limitations and implications are discussed
