E-Bike Commuting and Health in Overweight College Students

This randomized controlled trial investigates the effectiveness of e-bike commuting as a strategy to improve cardiometabolic health, physical activity levels, and psychological well-being in college students with a body mass index (BMI) of 25 kg/m² or higher. Eligible participants will be randomized to either a 12-week e-bike intervention group or a control group that continues usual commuting habits. Assessments will occur at baseline (Week 0), post-intervention (Week 12), and follow-up (Week 24). Each assessment will include VO₂peak testing using a graded cycle ergometer protocol, body composition assessment via BodPod, fasting fingerstick blood tests for glucose, cholesterol, and triglycerides, blood pressure and resting heart rate measurement, and self-report questionnaires evaluating motivation, stress, affect, mental health, and academic engagement. Participants will also complete a 30-minute submaximal cycling test during which affective responses will be recorded, and physical activity will be tracked over 7 days. Those assigned to the intervention group will receive a pedal-assist e-bike, helmet, and safety training and will be asked to ride at least four days per week for 12 weeks. The study aims to determine whether e-bike commuting can promote sustained physical activity and improve cardiometabolic and mental health outcomes in a population at risk for early health decline.
