The majority of young people do not meet the recommendations on physical activity for health. New innovative ways to motivate young people to adopt a physically active lifestyle are needed.
The study aimed to study the feasibility of an automated, gamified, tailored Web-based mobile service aimed at physical and social activation among young men.
A population-based sample of 496 young men (mean age 17.8 years [standard deviation 0.6]) participated in a 6-month randomized controlled trial (MOPO study). Participants were randomized to an intervention (n=250) and a control group (n=246). The intervention group was given a wrist-worn physical activity monitor (Polar Active) with physical activity feedback and access to a gamified Web-based mobile service, providing fitness guidelines, tailored health information, advice of youth services, social networking, and feedback on physical activity. Through the trial, the physical activity of the men in the control group was measured continuously with an otherwise similar monitor but providing only the time of day and no feedback. The primary outcome was the feasibility of the service based on log data and questionnaires. Among completers, we also analyzed the change in anthropometry and fitness between baseline and 6 months and the change over time in weekly time spent in moderate to vigorous physical activity.
Mobile service users considered the various functionalities related to physical activity important. However, compliance of the service was limited, with 161 (64.4%, 161/250) participants visiting the service, 118 (47.2%, 118/250) logging in more than once, and 41 (16.4%, 41/250) more than 5 times. Baseline sedentary time was higher in those who uploaded physical activity data until the end of the trial (P=.02). A total of 187 (74.8%, 187/250) participants in the intervention and 167 (67.9%, 167/246) in the control group participated in the final measurements. There were no differences in the change in anthropometry and fitness from baseline between the groups, whereas waist circumference was reduced in the most inactive men within the intervention group (P=.01). Among completers with valid physical activity data (n=167), there was a borderline difference in the change in mean daily time spent in moderate to vigorous physical activity between the groups (11.9 min vs -9.1 min, P=.055, linear mixed model). Within the intervention group (n=87), baseline vigorous physical activity was inversely associated with change in moderate to vigorous physical activity during the trial (R=-.382, P=.01).
The various functionalities related to physical activity of the gamified tailored mobile service were considered important. However, the compliance was limited. Within the current setup, the mobile service had no effect on anthropometry or fitness, except reduced waist circumference in the most inactive men. Among completers with valid physical activity data, the trial had a borderline positive effect on moderate to vigorous physical activity. Further development is needed to improve the feasibility and adherence of an integrated multifunctional service.

大多数年轻人未达到健康方面的体育活动建议标准。需要新的创新方法来激励年轻人采用积极的生活方式。
本研究旨在探讨一种自动化、游戏化、个性化的基于网络的移动服务在促进年轻男性身体和社交活动方面的可行性。
以人群为基础，选取496名年轻男性（平均年龄17.8岁[标准差0.6]）参与一项为期6个月的随机对照试验（MOPO研究）。参与者被随机分为干预组（n = 250）和对照组（n = 246）。干预组配备了一个腕戴式身体活动监测器（Polar Active），可提供身体活动反馈，并能访问一个游戏化的基于网络的移动服务，该服务提供健身指南、个性化健康信息、青年服务建议、社交网络以及身体活动反馈。在试验过程中，对照组男性的身体活动通过一个类似的监测器持续测量，但只提供时间，不提供反馈。主要结局是基于日志数据和问卷评估该服务的可行性。在完成试验者中，我们还分析了基线和6个月时人体测量学指标和身体素质的变化，以及每周中等至剧烈身体活动时间随时间的变化。
移动服务用户认为与身体活动相关的各种功能很重要。然而，该服务的依从性有限，有161名（64.4%，16
