正念步行活动可以维持感知和基于表现的认知。短期和长期的认知变化可能与正念步行练习有关。有必要进行随机对照试验来测试正念行走的功效。在行为干预中整合动态认知测量是可行的。正念练习和步行已经被单独联系起来，以维持老年人的认知。这项早期研究旨在通过评估将轻度步行与正念练习相结合的干预措施是否显示出改善老年人认知的有希望的迹象来建立概念验证。参与者（N = 25，法师= 72.4 ± 6.45）是居住在社区的老年人，他们参加了一个多月的监督下的正念步行计划（共8次，每周2次，30分钟包含正念技能的慢速步行）。他们在两次正念步行前后使用智能手机应用程序完成了基于表现的认知测量和主观评级。他们还在基线和整个计划之后完成了实验室内基于表现的认知测量和自我报告的认知测量。控制人口统计学、潜在协变量和时间趋势，观察到从注意步行前到注意步行后的认知和处理速度的短期改善（即，30分钟）进行多项动态认知测量（Cohen的ds范围= 0.46-0.66）。在基线和程序结束之间观察到处理速度和执行功能的长期改善（即，一个月），通过各种基于表现的认知测量（DS范围= 0.43-1.28）。其他认知领域没有观察到显著变化。这项早期研究（IIa期）提供了初步支持，即正念步行活动有希望维持老年人的认知能力。我们有希望的发现形成了将这种干预措施推进到一个完全有效的随机对照试验所需的证据的组成部分，该试验检查了与对照药物相比的方案疗效。有利的结果将为这种生活方式行为策略的发展提供信息，以促进成年后期健康的大脑衰老。
Mindful walking activity may sustain perceived and performance-based cognition. Short- and longer-term cognitive changes may be related to mindful walking practice. Randomized controlled trials are warranted to test the efficacy of mindful walking. Integrating ambulatory cognitive measures in a behavioral intervention is feasible. Mindfulness practice and walking have been linked individually to sustain cognition in older adults. This early-phase study aimed to establish proof-of-concept by evaluating whether an intervention that integrates light-intensity walking with mindfulness practices shows promising signs of improving cognition in older adults. Participants (N = 25, Mage = 72.4 ± 6.45) were community-dwelling older adults who engaged in a supervised mindful walking program over one month (8 sessions total, 2 sessions per week, 30-minute slow walking containing mindfulness skills). They completed performance-based and subjective ratings of cognitive measures in field before and after two mindful walking bouts using a smartphone app. They also completed in-lab performance-based and self-report cognitive measures at baseline and after the entire program. Controlling for demographics, potential covariates, and time trends, short-term improvements in perceived cognition and processing speed were observed from pre- to post-mindful walking sessions (i.e., 30 min) across multiple ambulatory cognitive measures (Cohen’s ds range = 0.46–0.66). Longer-term improvements in processing speed and executive function were observed between baseline and end of the program (i.e., one month) across various performance-based cognitive measures (ds range = 0.43–1.28). No significant changes were observed for other cognitive domains. This early-phase study (Phase IIa) provides preliminary support that mindful walking activity is promising for sustaining cognition in older adults. Our promising findings form the building blocks of evidence needed to advance this intervention to a fully powered randomized controlled trial that examines program efficacy with a comparator. Favorable outcomes will inform the development of this lifestyle behavioral strategy for promoting healthy brain aging in late adulthood.
