Most US adults are insufficiently active. One strategy individuals could use to increase physical activity is to exercise mindfully (i.e., while paying attention to present-moment experiences with acceptance. A mindfulness-based intervention for exercise can be delivered via an audio recording, which is advantageous in regard to time demands, cost, and dissemination potential. The aims of this parallel two-arm pilot randomized controlled trial were to assess the feasibility and acceptability of an audio-recorded mindfulness-based intervention and to assess whether the intervention resulted in a clinically meaningful difference in physical activity compared with the control condition.
Physically underactive adults (N = 50) were randomized to a mindfulness intervention condition in which they were instructed to exercise while listening to an audio-recorded mindfulness-intervention or an active control group in which they were instructed to exercise while using a heart rate monitor. Participants completed a 30-minute moderate intensity treadmill exercise bout during a baseline in-laboratory session in the manner in which they were randomized (i.e., mindfulness recording versus using a heart rate monitor) and instructed to exercise in this manner for the next week. At follow-up, acceptability was measured by self-report, feasibility by frequency of intervention use, and physical activity using both self-reported physical activity recall and an accelerometer.
The audio-recorded mindfulness-based physical activity intervention was rated as acceptable and feasible to use. Compared with the control group, the intervention also resulted in clinically meaningful differences in self-reported moderate-to-vigorous physical activity minutes (mean difference = 67.16 minutes) and accelerometer-measured minutes (mean difference = 35.48 minutes) during a 1-week follow-up.
The audio-recorded mindfulness-based physical activity intervention is a promising approach to increasing physical activity with good dissemination potential.
大多数美国成年人运动量不足。个人可用于增加身体活动的一种策略是正念锻炼（即，在以接纳的态度关注当下体验的同时进行锻炼）。基于正念的锻炼干预可以通过音频记录来实施，这在时间要求、成本和传播潜力方面具有优势。这项平行双臂试点随机对照试验的目的是评估基于音频记录的正念干预的可行性和可接受性，并评估与对照条件相比，该干预是否能在身体活动方面产生具有临床意义的差异。
身体活动不足的成年人（N = 50）被随机分为正念干预组，指导他们在听音频记录的正念干预时进行锻炼，或分为积极对照组，指导他们在使用心率监测器时进行锻炼。参与者在实验室基线阶段以随机分配的方式（即听正念记录与使用心率监测器）完成一次30分钟的中等强度跑步机锻炼，并被要求在接下来的一周内以这种方式锻炼。在随访时，通过自我报告测量可接受性，通过干预使用频率测量可行性，并使用自我报告的身体活动回忆和加速度计测量身体活动。
基于音频记录的正念身体活动干预被认为是可接受且可行的。与对照组相比，在1周的随访期间，该干预在自我报告的中等至剧烈身体活动分钟数（平均差异 = 67.16分钟）和加速度计测量的分钟数（平均差异 = 35.48分钟）方面也产生了具有临床意义的差异。
基于音频记录的正念身体活动干预是一种有前景的增加身体活动的方法，具有良好的传播潜力。
