摘要

背景/目的:直立性低血压(OH)是老年人的一种常见病,会增加跌倒的风险。本研究的目的是确定不同环境(水与陆地)对直立性低血压的影响,以及老年人在这些环境中行走所产生的影响。此外,我们还旨在评估两组人之间的反应差异:有 OH 的老年人和没有 OH 的老年人:方法:采用随机交叉设计,包括一次水中行走和另一次陆地行走,并有 1 到 3 天的冲洗期。在进行 15 分钟的步行训练之前、之后和之后 2 小时,分别进行静态血液动力学测量。结果显示,与陆地环境相比,有86%的人在步行过程中会出现心肌梗塞,而没有心肌梗塞的人在步行过程中不会出现心肌梗塞:结果:与陆地环境相比,浸泡在水中的老年人发生 OH 的频率降低了 86%。在减少频率的同时,平均动脉压也有所升高,而无羟色胺的参与者则没有出现这种变化。在水中行走或陆地行走后,从泳池中出来后立即进行评估时,OH 发作的频率相似。所有参与者在水上步行后都立即表现出平均动脉压升高,而在陆上步行后则没有。步行两小时后,所有参与者都表现出相似的平均动脉压和 OH 发作频率,与环境无关:结论:浸泡在水中可大幅降低老年人OH发作的频率。结论:在水中浸泡可大大降低老年人肺氧饱和度发作的频率,此外,在这两种环境中,肺氧饱和度发作的频率均不受之前步行锻炼的影响。意义/影响:这些发现强调了水上运动对于患有OH的老年人的安全性和潜在优势。

Impact of Land Versus Water Environments on Orthostatic Hypotension in Older Adults: A Randomized Crossover Study.

Background/objectives: Orthostatic hypotension (OH) is a common condition among older adults that increases the risk of falls. The study objectives are to determine the influence of distinct environments (water vs. land) on OH and the consequent effects of walking in these environments in older adults. Additionally, we aimed to assess the differences in response between two groups: older adults with OH and those without OH.

Methods: A randomized crossover design was utilized including one session involving water walking and the other session involving land walking, with a 1- to 3-day washout period. Orthostatic hemodynamic measurements were obtained before, immediately after, and 2 hr after a 15-min walking session. Two subgroups were formed for analysis: participants with OH (n = 14, 81 ± 7 years) and participants without OH (n = 11, 84 ± 7 years).

Results: Compared with the land environment, an 86% reduction in the frequency of OH episodes was noted when the older adults were immersed in water. This reduction was accompanied by greater mean arterial pressure, while participants without OH showed no such changes. The frequency of OH episodes was similar when assessed immediately after emerging from the pool following water-based walking or after land-based walking. All participants exhibited elevated mean arterial pressure immediately after water-based walking, but not after land-based walking. Two hours after walking, all participants demonstrated similar mean arterial pressure and frequency of OH episodes, regardless of the environment.

Conclusions: Water immersion resulted in a substantial reduction in the frequency of OH episodes among older adults. Additionally, the frequency of OH episodes was not affected by prior walking exercise in either environment. Significance/Implication: These findings underscore the safety and potential advantages of water-based exercise for older adults dealing with OH.

期刊介绍: The Journal of Aging and Physical Activity (JAPA) is a multidisciplinary journal that publishes peer-reviewed original research reports, scholarly reviews, and professional-application articles on the relationship between physical activity and the aging process. The journal encourages the submission of articles that can contribute to an understanding of (a) the impact of physical activity on physiological, psychological, and social aspects of older adults and (b) the effect of advancing age or the aging process on physical activity among older adults. In addition to publishing research reports and reviews, JAPA publishes articles that examine the development, implementation, and evaluation of physical activity programs among older adults. Articles from the biological, behavioral, and social sciences, as well as from fields such as medicine, clinical psychology, physical and recreational therapy, health, physical education, and recreation, are appropriate for the journal. Studies using animal models do not fit within our mission statement and should be submitted elsewhere.
