背景。下肢适应性下降是一个潜在的可改变的跌倒危险因素。本研究旨在比较两种运动项目——低成本的室内方步运动（SSE）和步行——对改善下肢健康的作用。我们随机将68名居住在社区的老年人（65-74岁）分为SSE组和步行组（W组）。在为期12周的方案中，SSE组参加了每周两次在当地健康中心进行的70分钟的锻炼，W组参加了每周进行的户外监督步行。W组被要求增加每天的步数。在项目前后，我们获得了11项已知跌倒危险因素的体能测试和3项自我报告量表的信息。随访8个月。在治疗后12周，两个运动组在腿部力量（1项）、平衡（2项）、敏捷性（2项）、反应时间（2项）和自我报告量表（1项）方面观察到显著差异；上交所组与X组时间交互在上述项目上表现出显著的改善。在没有组X时间相互作用的情况下，在涉及椅子站立、功能伸展和从躺着的位置站起来的测试中观察到显著的时间效应。随访期间，SSE组和W组人均年下降率分别为23.4%和33.3% （p = 0.31）。虽然还需要进一步的研究，但SSE在减少跌倒危险因素方面明显比步行更有效，似乎可以推荐它作为老年人的健康促进运动。
Background. Decreased fitness of the lower extremities is a potentially modifiable fall risk factor. This study aimed to compare two exercise programs-square-stepping exercise (SSE), which is a low-cost indoor program, and walking-for improving the fitness of the lower extremities.Methods. We randomly allocated 68 community-dwelling older adults (age 65-74 years) to either the SSE or walking group (W group). During the 12-week regimen, the SSE group participated in 70-minute exercise sessions conducted twice a week at a local health center, and the W group participated in outdoor supervised walking sessions conducted weekly. The W group was instructed to increase the number of daily steps. Prior to and after the program, we obtained information on 11 physical performance tests for known fall risk factors and 3 self-reported scales. The fall incidence was followed-up for 8 months.Results. At 12 weeks postregimen, significant differences were observed between the two exercise groups with respect to leg power (1 item), balance (2 items), agility (2 items), reaction time (2 items), and a self-reported scale (1 item); the SSE group demonstrated a marked improvement in the above-mentioned items with Group X Time interactions. Significant time effects were observed in the tests involving chair stands, functional reach, and standing up from a lying-down position without Group X Time interactions. During the follow-up period, the fall rates per person-year in the SSE and W groups were 23.4% and 33.3%, respectively (p =.31).Conclusion. Although further studies are required, SSE is apparently more effective than walking in reducing fall risk factors, and it appears that it may be recommended as a health promotion exercise in older adults.
