To examine the effect and feasibility of a 12-week programme of progressive resistance exercise on a group of nonagenarian (≥90 years) community-dwelling women.
An A-B single-subject experimental design was applied. Visual analyses were used for estimating the effect of the intervention. Outcome measurements were: Timed Up and Go (TUG), comfortable walking speed and 30-s chair stands. The programme comprised four exercises, following the principle of overload, aiming at improving strength in the main muscle groups. Feasibility of the progressive resistance intervention was assessed by recording the recruitment of participants, adherence to the intervention and adverse events.
Twenty-seven women were invited; eight women aged 90 and above agreed to participate and six completed the study. They suffered from one to 10 chronic medical conditions. All improved their performance in the TUG test. Five of the six participants achieved a higher walking speed (11-59%) and four of them improved on the 30-s chair-stand test with five to 10 stands. No major adverse events were reported.
Progressive resistance training was a safe and efficient method to enhance mobility and increase lower body strength in this heterogeneous group of nonagenarian community-dwelling women.
Progressive resistance (PRT) training was found to be a safe and efficient method to enhance mobility and increase lower body strength in a group of community-dwelling women 90+. Participants with the poorest initial functional performance had great benefits, and the improvements appeared already after a few weeks of PRT. PRT might be useful in the rehabilitation field and could be implemented in facilities such as day care and senior centres frequented by very old persons with mobility limitations.
研究一项为期12周的渐进性抗阻训练计划对一组90岁及以上社区居住老年女性的效果及可行性。
采用A-B单受试者实验设计。通过视觉分析评估干预效果。结果测量指标包括：定时起立行走测试（TUG）、舒适步行速度和30秒椅子站立测试。该计划包括四项练习，遵循超负荷原则，旨在增强主要肌肉群的力量。通过记录参与者的招募情况、对干预的依从性和不良事件来评估渐进性抗阻干预的可行性。
邀请了27名女性；8名90岁及以上的女性同意参与，6名完成了研究。她们患有1至10种慢性疾病。所有人在TUG测试中的表现都有所改善。6名参与者中有5名步行速度提高（11%-59%），其中4名在30秒椅子站立测试中增加了5至10次站立次数。未报告重大不良事件。
渐进性抗阻训练是一种安全有效的方法，可增强这组异质性的90岁及以上社区居住老年女性的活动能力并增加下肢力量。
发现渐进性抗阻（PRT）训练是一种安全有效的方法，可增强一组90岁以上社区居住老年女性的活动能力并增加下肢力量。初始功能表现最差的参与者受益最大，并且在进行几周的PRT训练后就出现了改善。PRT可能在康复领域有用，并且可以在日托中心和老年中心等设施中实施，这些设施常有行动不便的高龄老人光顾。
