办公室工作人员花了很大比例的时间坐着，往往在很长一段时间。研究表明，通过身体活动将这些长时间的发作分成较短的时间段更健康。我们评估了一种名为PEARL应用程序的情境感知活动教练的效果，这是一种基于身体活动预测模型提供活动建议的mHealth干预措施，包括过去和当前的身体活动和数字议程。参与了一项干预研究，其中他们使用了1周的干预措施，之前是1周的基线期。在干预前后进行测量。结果分析了14名参与者107天的数据。总的久坐时间没有因为使用干预而减少（基线vs干预：47.83.6 vs 46.8 +/- 3.0，n.s.）。当使用干预措施时，参与者将他们在长时间坐着的总时间（>= 45分钟）从每小时佩戴时间的19.3分钟减少到14.4分钟（p
BackgroundOffice workers spend a high percentage of their time sitting, often in long periods of time. Research suggests that it is healthier to break these long bouts into shorter periods by being physically active.ObjectiveWe evaluated the effect of a context-aware activity coach, called the PEARL app, an mHealth intervention that provides activity suggestions, based on a physical activity prediction model, consisting of past and current physical activity and digital agendas.MethodFifteen office workers, aged 50+, participated in an intervention study in which they used the intervention for 1 week, preceded by a 1-week baseline period. Measurements were taken before and after the intervention period.Results107 days of data from 14 participants were analysed. Total sedentary time was not reduced as a result of using the intervention (baseline vs intervention: 47.83.6 vs 46.8 +/- 3.0, n.s.). When using the intervention, participants reduced their total time spent in long sitting bouts (>= 45 min) from 19.3 to 14.4 min per hour of wear time (p
