穿戴式科技對身體活動促進之影響：系統性文獻回顧

Introduction: Wearable technology has become a new way to motivate people to engage in physical activity. Wearable technology can lead to health behavior modification because of the functions of goal settings, in-time feedback, social support and motivation enhancement. In light of this, the purpose of the present study was to understand the benefits of wearable technology for physical activity through a systematic literature review, including smart watches, smart wristbands, and mobile applications. Methods: This study refers the systematic reviews and meta-analyses for academic search and screening. The six databases, EBSCO, ScienceDirect, Web of Science, MEDLINE, Scopus® and Airiti Library were mainly used. The inclusion criteria were an experiment design, the intervention should be wearable technology products, outcome variables were physical activity related variables; the exclusion criteria were non-randomized controlled trials, wearable technology products are only used for monitoring or measurement. Cochrane risk-of-bias tools were used to evaluate the research quality. Results: There were a total of 18 evidence-based articles. The systematic literature review found that wearable technology has a positive impact on physical activity. In most studies, the number of daily steps, moderate-to-vigorous physical activity and light physical activity of the experimental group after experimental intervention were increased and sedentary time was reduced. However, most of studies did not show the significant effect within the experimental group, only a few studies had a significant effect between the groups. In the design of this study, the participants covered all age groups, most studies ranged from 30 to 70 individuals, the intervention time were between 12 to 24 weeks. 22.22% used mobile apps, and 77.78% used wearable wristbands and their affiliated applications as interventions. Conclusion: Wearable technology is one of the new, interesting and personalized ways to promote physical activity. It is expected to improve physical activity and reduce the risk of chronic diseases. The results of the present study might provide suggestions for future research and design, and also a reference for the development of wearable technology products in the sports and information technology industry.
