AbstractBackgroundPeriods of prolonged lockdown increase the risk of physical inactivity, which can contribute to physical decline among older adults. Online technology could be an innovative solution to promote physical activity (PA) habits in this context. The goal of this study was to examine and compare the acceptability, feasibility, and potential benefits of 2 modalities of web-based PA interventions in older adults during the coronavirus disease 2019 lockdown.MethodsEighty-three nonphysically active community-dwelling older adults (aged 60 and older) were randomized to a 12-week web-based PA intervention delivered either in a live group (LG; n = 38) or a recorded group (RG; n = 45). Acceptability, feasibility as well as functional capacities, physical performance, quality of life, and PA level were assessed pre and postintervention.ResultsThere were fewer dropouts in the LG than RG (LG: 16% vs RG: 46%). However, adherence rate (LG: 89%; RG: 81%), level of satisfaction (LG: 77% vs RG: 64%), and enjoyment (LG: 68% vs RG: 62%) were similar across groups, even if the participants found the intervention slightly difficult (LG: 58% vs RG: 63%). Both groups significantly improved on functional capacities, physical performance, and quality of life. Only the LG showed significant improvements in perceived health and PA level. The LG showed greater improvements in physical performance and quality of life than the RG.ConclusionWeb-based PA interventions are feasible, acceptable, and beneficial for improving functional capacities and physical performance during periods of lockdown. However, the interactive web and live modalities appear to be more effective for promoting some of these outcomes than recorded and individual modalities.

基于网络的身体活动干预措施是防止社区老年人在隔离期间身心健康下降的可行且有益的解决方案

摘要背景长时间的封锁会增加缺乏身体活动的风险，这可能会导致老年人的身体状况下降。在这种情况下，在线技术可能是促进身体活动（PA）习惯的创新解决方案。本研究的目的是检查和比较 2019 年冠状病毒病封锁期间老年人的两种基于网络的 PA 干预方式的可接受性、可行性和潜在益处。方法83 名不活跃的社区老年人（60 岁及以上）被随机分配接受为期 12 周的基于网络的 PA 干预，分为现场组（LG；n = 38）或记录组（RG；n = 45）。在干预前后评估可接受性、可行性以及功能能力、身体表现、生活质量和 PA 水平。结果LG 的辍学率低于 RG（LG：16% vs RG：46%）。然而，各组的依从率（LG：89％；RG：81％）、满意度（LG：77％ vs RG：64％）和享受程度（LG：68％ vs RG：62％）相似，即使如果参与者发现干预稍微困难（LG：58％ vs RG：63％）。两组的功能能力、身体表现和生活质量都有显着提高。只有 LG 在感知健康和 PA 水平方面表现出显着改善。LG 在身体机能和生活质量方面比 RG 表现出更大的改善。结论基于网络的 PA 干预措施是可行的、可接受的，并且有利于提高锁定期间的功能能力和身体表现。然而，交互式网络和直播方式似乎比记录和个人方式更有效地促进其中一些成果。
