Overweight and obesity in children and adolescents is a significant health problem, and lack of physical activity may be a factor related to obesity. In this study, we explored the wearable fitness watch to monitor the physical activity promoted situation of overweight and obese schoolchildren. Participants were overweight schoolchildren divided into two groups, the study group (n=41) and the control group (n=44). In the control group, the wearable fitness watch only displays the time. In the study group, each week, participants set up the goal, which increases the steps by 10% from baseline steps to reach 10,000 steps. The ANOVA is adopted to analyze the parameters such as the average daily number of steps, moderate to vigorous physical activity (MVPA). The results indicated the study group increase and improved daily walking steps and MVPA accumulation time in 8 weeks. The wearable fitness watch can help to promote the physical activity of overweight children.
