Article Title: Accuracy of steps measured by smartphones-based WeRun compared with ActiGraph-GT3X accelerometer in free-living conditions

doi: 10.3389/fpubh.2022.1009022

Figure Lengend Snippet: Influencing factors of the correlation between WeRun step counts and ActiGraph-GT3X accelerometer step counts.

Article Snippet: It may be that the time of carrying smartphones and wearing the ActiGraph-GT3X accelerometer was different between weekdays and weekends, thus causing the correlation between the ActiGraph-GT3X accelerometer and the WeChat app on weekends to be lower than that on weekdays ( ).

Article Snippet: 15. , Z. C. Pope 2020 Journal of American College Health , The experimental group used the MapMyFitness smartphone application to log and track physical activity (PA) and participated in a Social Cognitive Theory-based, Facebook-delivered health education intervention that lasted 10 weeks. The comparison group was only included in a separate, but content-identical, Facebook intervention. , Average daily minutes of sedentary behavior and moderate-to-vigorous PA (MVPA) was measured via Actigraph GT3X at baseline, 5 weeks, and 10 weeks. Participants height, weight, and body fat percentage were also measured at baseline and at 10 weeks. The YMCA 3-min Step Test40 was administered to evaluate cardiovascular fitness at baseline and at 10 weeks. , A modest sedentary behavior reduction in the experimental group was observed. Additionally, both groups demonstrated slight reductions in weight and body fat percentage. , A low-burden and well-integrated social media-based intervention is feasible and of interest to college students, possibly improving select health behaviors and outcomes. PA-oriented smartphone application offered limited additional benefit. , .
