Abstract
Purpose: Physical inactivity is linked with several chronic diseases and poor academic outcomes. This study aimed to examine the effect an under-the-desk band would have on middle school students' physical activity level, and academic engagement. Methods: Two local middle school classrooms (n = 42, M = 20, F = 22) participated in the study, which was conducted over 14 weeks. Physical activity was measured with accelerometry, and academic engagement was assessed using momentary time sampling. Enrolled participants were provided an accelerometer to wear upon entering the classroom. The baseline period lasted for 36 days. During the intervention period, which lasted for the next 30 days, an under-the-desk band was provided to students to freely fidget at their desks. After the study, 13 participants (M = 5, F = 8) in Class A were included in final physical activity analysis, and the 6 participants (M = 3, F = 3) in Class B were included in the academic engagement analysis. Results: Class A had significant increases in percentage of sedentary time (MD = -12.91%, ES = .88) in addition to significant decreases in the percentage of light (MD = 8.82%, ES = .67), moderate (MD = 3.08%, ES = .84), and vigorous (MD = -.04%, ES = .63) physical activity time during the intervention period compared to the baseline period. No significant or meaningful changes occurred in academic engagement with the use of the under-the-desk band. Conclusions: This study high- lights the importance of finding appropriate methods to increase physical activity for adolescents.
目的:缺乏身体活动与几种慢性疾病和学习成绩差有关。本研究旨在检验桌子下的手环对中学生身体活动水平和学习投入的影响。方法:当地两个中学教室(n = 42, M = 20, F = 22)参与研究,为期14周。身体活动用加速度计测量,学习参与用瞬时时间抽样评估。注册的参与者在进入教室时佩戴一个加速度计。基线期36 d。在接下来的30天的干预期间,研究人员给学生们提供了一个桌子下的乐队,让他们在桌子前自由地坐立不安。研究结束后,A班13名参与者(M = 5, F = 8)被纳入最终体育活动分析,B班6名参与者(M = 3, F = 3)被纳入学业投入分析。结果:A类患者久坐时间的百分比显著增加(MD = -12.91%, ES = 0.88),轻度(MD = 8.82%, ES = 0.67)、中度(MD = 3.08%, ES = 0.84)和剧烈(MD = -)运动的百分比显著降低。04%, ES = 0.63)干预期的体力活动时间与基线期比较。在课桌下使用手环后,学生的学术参与度没有发生显著或有意义的变化。结论:本研究强调了寻找适当方法增加青少年身体活动的重要性。
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
