To investigate the impact of high-intensity walking training (HIWT) on prefrail and frail older adults, five assisted living residents underwent a supervised 12-session intervention. The intervention consisted of 30 min of HIWT at 70-80% of heart rate reserve or ratings of 15 to 17 (hard to very hard) on the Borg Rating of Perceived Exertion scale. Training included walking at fast speeds, multi-directions, stairs, and outdoor surfaces with and without an assistive device. Training significantly reduced frailty using the SHARE-FI (p = .008), increased fast gait speed (p = .01), improved 6-min walk test distance (p = .03), and enhanced Berg Balance Scale scores (p = .03). There were no adverse events and all participants reached target training intensity in all 12 sessions. Participants viewed the walking intervention as highly satisfactory (9.6/10 on a Likert scale) and 100% recommended that the assisted living facility should offer HIWT as part of routine programming.
为了研究高强度步行训练（HIWT）对虚弱前期和虚弱的老年人的影响，五名辅助生活居民接受了为期12节的监督干预。干预包括以心率储备的70%-80%进行30分钟的HIWT，或在Borg自觉用力程度量表上达到15至17级（从难到非常难）。训练包括快速行走、多方向行走、上下楼梯以及在有无辅助设备的户外路面行走。使用SHARE-FI评估，训练显著降低了虚弱程度（p = 0.008），提高了快速步态速度（p = 0.01），改善了6分钟步行测试距离（p = 0.03），并提高了伯格平衡量表得分（p = 0.03）。没有不良事件发生，所有参与者在全部12节训练中均达到了目标训练强度。参与者对步行干预的满意度很高（李克特量表评分为9.6/10），100%的参与者建议辅助生活设施应将HIWT作为常规项目的一部分提供。
