Whether physical activity (PA) tracking devices are associated with PA motivation in young adults is largely unknown. We compared total PA minutes per week, total minutes walking/week, meeting moderate-to vigorous PA guidelines, and past-year activity tracking across motivation cluster profiles among 799 young adults. Participants with “self-determined” profiles reported the highest total PA minutes/week followed by participants with “low intrinsic,” “controlled self-determined,” and “high external” profiles. A behavior regulation profile X activity tracking frequency interaction was not significant. Behavior regulation profiles may need to be considered in PA interventions using activity trackers.

身体活动 (PA) 跟踪设备是否与年轻人的 PA 动机相关在很大程度上是未知的。我们比较了每周总 PA 分钟数、每周步行总分钟数、满足中度到剧烈的 PA 指南，以及对 799 名年轻人的动机集群概况的过去一年的活动跟踪。具有“自我确定”概况的参与者报告的总 PA 分钟/周最高，其次是具有“低内在”、“受控自我确定”和“高外部”概况的参与者。行为调节配置文件 X 活动跟踪频率交互不显着。在使用活动跟踪器的 PA 干预中可能需要考虑行为调节概况。
