Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.

Primary outcome measures: Change in Total Physical Activity Measured by the Chinese Version of the International Physical Activity Questionnaire , Baseline and Week 4; Change in Stage of Exercise Behavior Change , Baseline and Week 4; Change in Exercise Self-Efficacy Measured by the Chinese Version of the Exercise Self-Efficacy Scale , Baseline and Week 4; Change in Perceived Benefits of Exercise Measured by the Chinese Version of the Decisional Balance Scale , Baseline and Week 4; Change in Perceived Barriers to Exercise Measured by the Chinese Version of the Decisional Balance Scale , Baseline and Week 4. 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.
