To determine if stroke patients without specific aerobic training experience a change in the first 6 months after stroke.
Descriptive, longitudinal study with repeated measures of exercise capacity at 1, 2, 3, and 6 months after stroke.
Exercise testing laboratory in a tertiary care hospital.
Consecutive sample of 25 patients (mean age +/- standard deviation, 64.1+/-13.6 y) 1 month after first ischemic stroke.
Not applicable. Main Outcome Measures Peak oxygen consumption (Vo(2)peak) was measured by open-circuit spirometry during maximal effort treadmill walking with 15% body-weight support.
Mean Vo(2)peak increased from 14.8+/-5.3 mL x kg(-1). min(-1) at 1 month to 17.3+/-7.0 mL x kg(-1).min(-1) at 6 months after stroke (P=.003) or from 61.7%+/-16% to 71.3%+/-23% of age- and sex-related normative values for sedentary healthy adults (P=.008).
Despite improvements in Vo(2)peak and other indices of cardiovascular training between 1 and 6 months poststroke, substantial limitations in exercise capacity persisted. Further study is needed to determine the extent to which these limitations can be modified through aerobic conditioning.
确定没有特定有氧运动训练经历的中风患者在中风后的前6个月是否发生变化。
描述性纵向研究，在中风后1、2、3和6个月重复测量运动能力。
三级护理医院的运动测试实验室。
首次缺血性中风后1个月的25名患者连续样本（平均年龄±标准差，64.1±13.6岁）。
不适用。主要观察指标在最大努力跑步机行走并给予15%体重支持时，通过开路肺活量测定法测量峰值耗氧量（Vo₂峰值）。
中风后1个月时平均Vo₂峰值为14.8±5.3 mL·kg⁻¹·min⁻¹，6个月时增至17.3±7.0 mL·kg⁻¹·min⁻¹（P = 0.003），或从久坐健康成年人年龄和性别相关标准值的61.7%±16%增至71.3%±23%（P = 0.008）。
尽管中风后1至6个月期间Vo₂峰值和其他心血管训练指标有所改善，但运动能力仍存在显著限制。需要进一步研究以确定通过有氧训练能在多大程度上改善这些限制。
