中国古代在用河石做成的小路上赤脚行走，在很多方面都有益于健康。俄勒冈研究所的研究人员发现，用鹅卵石铺成的垫子走路不仅能改善身体的平衡和活动能力，而且比普通走路更能降低血压。

研究人员对一组108名60-92岁的老年人进行了研究，研究对象是60-92岁不运动的老年人。参与者被随机分配到普通步行组或鹅卵石铺地步行组。每组每周至少散步三次，每次30分钟，另外每周进行三次60分钟的集体锻炼，持续16周。

　

　

为什么走鹅卵石路可以降低血压还不清楚。其中一种可能性是，它的作用就像一个以重力为基础的按摩，在这个过程中可以放松身体，降低血压。

　

　

虽然研究结果对鹅卵石行走是积极的，但研究作者指出，他们的研究有一些局限性。这项研究缺乏力量测量。此外，评估人员知道每个参与者所在小组的身份，这可能是导致结果偏差的原因之一。然而，这种盲目的缺失被其他因素所抵消:评估人员既不知道以前的评估分数，也不知道研究假设，评估是基于标准化的、经过验证的客观绩效评估。建议进行更多的研究。

这项研究发表在2005年的《美国老年医学会杂志》上;[53]8,1305 - 12)。

Barefoot Cobblestone Walking Lowers Blood Pressure

　

by Shirley Archer, JD, MA on Jul 01, 2006 The ancient Chinese practice of walking barefoot on paths made of river stones is good for health in more ways than one. Researchers from Oregon Research Institute, motivated to identify low-cost forms of exercise to improve functioning in older adults, found that cobblestone mat walking not only improved balance and mobility but also reduced blood pressure more than regular walking, Investigators studied the benefits of cobblestone walking compared to regular walking, in addition to weekly group exercise sessions, in a group of 108 inactive older adults aged 60–92 years. Participants were randomly assigned to either a regular walking group or a cobblestone mat walking group. Each group walked for 30 minutes at least three times per week in addition to taking a 60-minute group exercise session three times per week over a 16-week period. Why cobblestone walking lowers blood pressure is unclear. One possibility is that it acts like a gravity-based massage that relaxes the body and lowers blood pressure in the process, according to John Fisher, PhD, one of the researchers (October 2005 Harvard Heart Letter). While the outcome was positive for cobblestone walking, the study authors noted that their research had some limitations. The study lacked strength measurements. Also, assessors knew the identity of each participant’s group, which may have contributed to outcome bias. This lack of blinding, however, was offset by other factors: Assessors didn’t know either previous assessment scores or the study hypothesis, and assessments were based on standardized and validated objective performance evaluations. More research was recommended. The study appeared in the Journal of the American Geriatrics Society (2005; [53] 8, 1305–12).
