Most exercise interventions for stroke survivors are designed for those who have substantial motor and functional disabilities. There remains a group of well-recovered stroke survivors who have yet to be investigated in terms of their physical capacity and fitness levels.
To assess and compare the physical capacities of independently ambulant, community-dwelling stroke survivors to age- and gender-matched comparison participants.
Data were obtained from 17 stroke survivors participating in the How FITSS? Trial, all with functional ambulatory category of ≥4 and a self-selected walking speed ≥0.8 m s. An additional 17 healthy control participants were recruited. Cardiorespiratory fitness (CRF) was measured using oxygen consumption (VO), and additional measures of walking speed (m s), leg strength and body composition were also assessed. Differences between groups were assessed by matched pairs t-tests. Effect sizes were calculated using Cohen's d.
There were no significant differences in age, BMI, muscle mass or body fat between groups (p > 0.05). Peak VO was lower in the stroke group for the shuttle walk test (p = 0.037) and progressive cycle test (p = 0.019), as were all CRF test performance measures (p < 0.05). Stroke survivors walked significantly (p < 0.001) slower at both self-selected and fast speeds. Effect sizes of group differences for all leg strength variables were medium to large, with peak torque lower in the stroke group for all trials.
Despite being independently ambulant and community dwelling, the CRF, walking speed and leg strength of this group were reduced compared to non-stroke comparison participants. These patients may benefit from undertaking targeted exercise programmes.
大多数针对中风幸存者的运动干预措施是为那些有严重运动和功能障碍的人设计的。仍有一组恢复良好的中风幸存者，他们的身体能力和健康水平尚未得到研究。
评估并比较能够独立行走、居住在社区的中风幸存者与年龄和性别匹配的对照参与者的身体能力。
数据来自17名参与“How FITSS?”试验的中风幸存者，他们的功能步行分类均≥4，自我选择的步行速度≥0.8米/秒。另外招募了17名健康对照参与者。使用耗氧量（VO）测量心肺适能（CRF），还评估了步行速度（米/秒）、腿部力量和身体成分的其他指标。通过配对t检验评估组间差异。使用科恩d值计算效应量。
两组在年龄、体重指数、肌肉量或体脂方面无显著差异（p>0.05）。在往返步行测试（p = 0.037）和渐进性自行车测试（p = 0.019）中，中风组的峰值VO较低，所有CRF测试性能指标也较低（p<0.05）。中风幸存者在自我选择速度和快速行走时明显较慢（p<0.001）。所有腿部力量变量的组间差异效应量为中等至较大，中风组在所有试验中的峰值扭矩均较低。
尽管该组中风幸存者能够独立行走且居住在社区，但与非中风对照参与者相比，他们的CRF、步行速度和腿部力量有所下降。这些患者可能受益于针对性的运动计划。
