相当大比例的青少年没有达到推荐的体力活动水平。找到激励青少年积极活动的新方法对身心健康很重要。像Fitbit这样的健康和健身可穿戴设备有潜力激励年轻人活跃起来。本研究的目的是探讨佩戴Fitbit 5周是否会影响青少年(14-15岁)的身体满意度、体力活动动机和客观体力活动。这项研究是对英国一所高中的62名学生(38名男孩，24名女孩)进行的，他们来自英国一所高中的五个高中体育课，年龄在14-15岁之间。小学生佩戴Fitbit Charge HR 5周。学生们在5周前和5周后佩戴加速度计7天，以探索体力活动水平的变化。学生们还完成了测试前和测试后的问卷，以衡量身体满意度和体育活动动机。使用重复测量多变量方差分析来分析数据，以探索不同时间和性别之间得分的差异。在佩戴Fitbit后，小学生的自主动机下降，运动动机和受控动机都有所增加，但这些差异不显著。与这些消极的动机结果一致的是，学生在佩戴Fitbit后从事的中等到剧烈的体育活动明显减少。学生们在佩戴Fitbit后，身体满意度也有了显著的提高。这些发现表明，如果没有支持，Fitbit可能会降低学生的积极性，并降低青少年的体力活动水平。
Significant proportions of adolescents do not meet recommended physical activity levels. Finding new ways to motivate adolescents to be active is important for physical and psychological well-being. Health and fitness wearables such as the Fitbit have the potential to motivate young people to be active. The aim of this study is to explore if wearing a Fitbit for 5 weeks impacted adolescents' (14-15 year olds) body satisfaction, physical activity motivation and objective physical activity. The study was conducted with 62 (38 boys, 24 girls) pupils aged 14-15, from five high school physical education classes, in one high school in the United Kingdom. Pupils wore a Fitbit Charge HR for 5 weeks. Pupils wore an accelerometer for 7 days pre and post the 5-week period to explore changes in physical activity levels. Pupils also completed pre-post-test questionnaires to measure body satisfaction and physical activity motivation. Data were analysed using a repeated measures Multivariate Analysis of Variance to explore differences in scores between time and sex. After wearing the Fitbit, the pupils experienced declines in autonomous motivation and increases in both amotivation and controlled motivation, but these differences were not significant. In line with these negative motivational outcomes, pupils engaged in significantly less moderate to vigorous physical activity after wearing the Fitbit. Significant increases in body satisfaction were also experienced by pupils after wearing the Fitbit. These findings suggest that without support Fitbits may make pupils less motivated to be active and decrease the physical activity levels of adolescents.
