Patel MS, et al. - In a 36-week randomized clinical trial with a 24-week interruption and 12-week follow-up period, researchers evaluated 602 adults from 40 states with BMI values of ≥ 25 to determine the efficiency of support, collaboration, and competition within a behaviorally designed gamification intervention to enhance physical activity among overweight and obese adults. Following the observation, all three gamification interventions significantly improved physical activity during the 24-week intervention, and competition was the most productive. Moreover, in all arms during follow-up, physical activity was decreased, and only remained significantly greater in the competition arm vs the control arm.
