Physical activity provides fundamental health benefits for children and youth. The aim of the study was to explore the possibility of conducting an empowerment-inspired intervention and examine the impact of the intervention in promoting moderate and vigorous physical activity (MVPA) among adolescents.
A nonrandomized trial with a concurrent control group was carried out. Physical activity data were collected before and after the intervention with daily questions by short message service. Self-efficacy, social support, and attitude were also measured before and after the intervention since they were possible mediators.
The intervention was created by the students, the researchers, and the teachers using an empowerment-based approach. Students in the intervention group (n = 21) increased their MVPA on average by 4.9 (SD = 28.9) minutes per day, and students in the control group (n = 25) reduced their MVPA on average by 25.4 (SD = 23.0) minutes per day (p = .000).
The intervention might have contributed to a promotion of physical activity among students in the intervention group. The most valuable contribution this study provides is the knowledge that it is possible to develop and conduct an empowerment-inspired intervention to promote adolescent physical activity.
体育活动对儿童和青少年的健康具有重要意义。本研究旨在探讨开展一项以赋权为灵感的干预措施的可能性，并检验该干预措施对促进青少年中等强度和剧烈身体活动（MVPA）的影响。
开展了一项设有同期对照组的非随机试验。通过短信每日提问的方式在干预前后收集身体活动数据。由于自我效能、社会支持和态度可能是中介因素，因此在干预前后也对其进行了测量。
干预措施由学生、研究人员和教师采用基于赋权的方法制定。干预组（n = 21）的学生平均每天的MVPA增加了4.9（标准差 = 28.9）分钟，而对照组（n = 25）的学生平均每天的MVPA减少了25.4（标准差 = 23.0）分钟（p = .000）。
该干预措施可能有助于促进干预组学生的身体活动。本研究最有价值的贡献在于，它让我们知道有可能开发并开展一项以赋权为灵感的干预措施来促进青少年的身体活动。
