目的：身体活动是健康老龄化和肥胖管理的关键因素。本研究的目的是测试实施意图（IIs）对身体活动和体重的影响，在不活跃的肥胖老年adults.Design and measures：在基线，101肥胖（I类和II类）老年人被随机分配到实验或对照条件。在实验条件下，除了共同的干预活动，提供了IIs。体力活动（主要结局）通过计步器进行评估。结果：所有结果均未观察到IIs的主要影响（ps>0.21）。对于每天的步数，观察到显著的时间x条件相互作用（p=0.01）。在6个月的随访中，实验条件下参与者的身体活动改善更大（d=0.59）。没有测量的认知调节或介导IIs.Conclusion：结果表明，IIs可能是适当的，有利于维持体力活动不活跃的肥胖老年人。然而，这种技术似乎对减肥的影响有限。
Objectives: Physical activity is a key factor for healthy ageing and obesity management. The aim of this study was to test the effect of implementation intentions (IIs) on physical activity and body weight among inactive obese older adults.Design and measures: At baseline, 101 obese (classes I and II) older adults were randomised to an experimental or a control condition. IIs were delivered in the experimental condition in addition to the common intervention activities. Physical activity (primary outcome) was assessed by means of pedometers. The effect of IIs on body weight (secondary outcome) was also evaluated.Results: No main effects for IIs were observed for all outcomes (ps>0.21). A significant time x condition interaction was observed for the number of steps per day (p=0.01). At the 6-month follow-up, the improvement in physical activity was greater among participants in the experimental condition (d=0.59). None of the measured cognitions moderated or mediated IIs.Conclusion: Results suggest that IIs could be appropriate to favour the maintenance of physical activity among inactive obese older adults. However, this technique seems to have limited impacts over and above common intervention activities on weight loss.
