To determine the relative effects of cobblestone mat walking, in comparison with regular walking, on physical function and blood pressure in older adults.
Randomized trial with allocation to cobblestone mat walking or conventional walking.
General community in Eugene, Oregon.
One hundred eight physically inactive community-dwelling adults aged 60 to 92 (mean age+/-standard deviation=77.5+/-5.0) free of neurological and mobility-limiting orthopedic conditions.
Participants were randomized to a cobblestone mat walking condition (n=54) or regular walking comparison condition (n=54) and participated in 60-minute group exercise sessions three times per week for 16 consecutive weeks.
Primary endpoint measures were balance (functional reach, static standing), physical performance (chair stands, 50-foot walk, Up and Go), and blood pressure (systolic, diastolic). Secondary endpoint measures were Short Form-12 physical and mental health scores and perceptions of health-related benefits from exercise.
At the 16-week posttest, differences between the two exercise groups were found for balance measures (P=.01), chair stands (P<.001), 50-foot walk (P=.01), and blood pressure (P=.01) but not for the Up and Go test (P=.14). Although significant within-group changes were observed in both groups for the secondary outcome measures, there were no differences between intervention groups.
Cobblestone mat walking improved physical function and reduced blood pressure to a greater extent than conventional walking in older adults. Additional benefits of this walking program included improved health-related quality of life. This new physical activity may provide a therapeutic and health-enhancing exercise alternative for older adults.
确定与常规步行相比，鹅卵石步道行走对老年人身体功能和血压的相对影响。
随机试验，参与者被分配至鹅卵石步道行走组或常规行走组。
俄勒冈州尤金市的普通社区。
108名年龄在60至92岁（平均年龄±标准差 = 77.5±5.0）、身体不活跃的社区居住成年人，无神经和行动受限的骨科疾病。
参与者被随机分配至鹅卵石步道行走组（n = 54）或常规行走对照组（n = 54），连续16周每周参加3次60分钟的团体锻炼课程。
主要终点指标为平衡能力（功能性伸展、静态站立）、身体表现（从椅子上站起、50英尺步行、起身行走测试）和血压（收缩压、舒张压）。次要终点指标为简短健康调查问卷12项身体和心理健康评分以及对运动带来的健康相关益处的认知。
在16周后的测试中，发现两组锻炼组在平衡能力测量指标（P = 0.01）、从椅子上站起（P < 0.001）、50英尺步行（P = 0.01）和血压（P = 0.01）方面存在差异，但在起身行走测试中无差异（P = 0.14）。尽管两组在次要结局指标上均观察到组内显著变化，但干预组之间无差异。
与常规步行相比，鹅卵石步道行走能更大程度地改善老年人的身体功能并降低血压。该步行计划的其他益处包括改善与健康相关的生活质量。这种新的体育活动可能为老年人提供一种治疗性和促进健康的运动选择。
