Brief Summary

This randomized controlled study evaluated the effects of a 4-week Brain Breaks® exercise video intervention on physical activity and Transtheoretical Model-related psychosocial factors among overweight and obese children and adolescents in China. Participants were randomly assigned to an intervention group or a control group. The intervention group participated in short, video-based physical activity sessions during school breaks, while the control group did not receive the Brain Breaks intervention. Outcomes included physical activity participation, stage of exercise behavior change, exercise self-efficacy, perceived benefits of exercise, and perceived barriers to exercise.

Outcome Measures

Primary Outcomes (5)

• Change in Total Physical Activity Measured by the Chinese Version of the International Physical Activity Questionnaire

  Physical activity was assessed using the 7-item Chinese version of the International Physical Activity Questionnaire (IPAQ-C), which assesses physical activity intensity and sitting time during the previous 7 days. Total physical activity was expressed as metabolic equivalent task minutes per week (MET-min/week). Higher values indicate a greater amount of physical activity. Change from baseline to Week 4 was evaluated between the intervention and control groups.

  Baseline and Week 4

• Change in Stage of Exercise Behavior Change

  Stage of exercise behavior change was assessed according to the Transtheoretical Model. Participants were classified into one of five stages: precontemplation, contemplation, preparation, action, or maintenance. Changes in stage of exercise behavior from baseline to the end of the 4-week intervention were evaluated between groups.

  Baseline and Week 4

• Change in Exercise Self-Efficacy Measured by the Chinese Version of the Exercise Self-Efficacy Scale

  xercise self-efficacy was assessed using the 18-item Chinese version of the Exercise Self-Efficacy Scale. Each item is rated on a 5-point Likert scale from 1 (not at all confident) to 5 (completely confident). The mean score ranges from 1 to 5, with higher scores indicating greater exercise self-efficacy. Change from baseline to Week 4 was evaluated between the intervention and control groups.

  Baseline and Week 4

• Change in Perceived Benefits of Exercise Measured by the Chinese Version of the Decisional Balance Scale

  Perceived benefits of exercise were assessed using the Benefits subscale of the 10-item Chinese version of the Decisional Balance Scale. The Benefits subscale consists of 5 items rated on a 5-point scale. The mean subscale score ranges from 1 to 5, with higher scores indicating greater perceived benefits of exercise. Change from baseline to Week 4 was evaluated between the intervention and control groups.

  Baseline and Week 4

• Change in Perceived Barriers to Exercise Measured by the Chinese Version of the Decisional Balance Scale

  Perceived barriers to exercise were assessed using the Barriers subscale of the 10-item Chinese version of the Decisional Balance Scale. The Barriers subscale consists of 5 items rated on a 5-point scale. The mean subscale score ranges from 1 to 5, with higher scores indicating greater perceived barriers to exercise and therefore a less favorable outcome. Change from baseline to Week 4 was evaluated between the intervention and control groups.

Study Arms (2)

Brain Breaks Exercise Video Intervention

EXPERIMENTAL

Participants in this arm received a 4-week Brain Breaks® exercise video intervention. The intervention consisted of approximately 10 minutes of moderate-to-high-intensity video-guided physical activity during school breaks each day. Participants followed short exercise video segments designed to increase physical activity and support exercise behavior change.

Behavioral: Video-Guided Physical Activity Program

Control

NO INTERVENTION

Participants in this arm did not receive the Brain Breaks® exercise video intervention during the study period and continued their usual school activities.

Interventions

Video-Guided Physical Activity Program BEHAVIORAL

Participants assigned to the intervention group received a 4-week video-guided physical activity program using Brain Breaks exercise videos. The intervention consisted of approximately 10 minutes of moderate-to-high-intensity physical activity during school breaks each day. Participants followed short exercise video segments designed to increase physical activity participation and support exercise behavior change. The intervention was delivered in the school setting during the study period.
