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.
