To evaluate exercise capacity of patients with a poststroke interval of less than 1 month.
Prospective, cohort, observational study.
Exercise testing laboratory in a tertiary care hospital.
Twenty-nine patients (mean age +/- standard deviation, 64.9+/-13.5 y) with a poststroke interval of 26.0+/-8.8 days.
Not applicable.
Peak exercise capacity (VO(2)peak) was measured by open-circuit spirometry during maximal effort treadmill walking with 15% body-weight support.
Mean VO(2)peak was 14.4+/-5.1 mL. kg(-1). min(-1) or 60%+/-16% of age- and sex-related normative values for sedentary healthy adults.
Exercise capacity approximately 1 month after stroke was compromised. Further research is needed to elucidate the physiologic basis of this low capacity.
评估卒中后间隔时间小于1个月的患者的运动能力。
前瞻性队列观察性研究。
三级护理医院的运动测试实验室。
29例患者（平均年龄±标准差，64.9±13.5岁），卒中后间隔时间为26.0±8.8天。
不适用。
在最大努力的跑步机行走过程中，使用15%体重支持，通过开路肺量计测量峰值运动能力（VO₂峰值）。
平均VO₂峰值为14.4±5.1 mL·kg⁻¹·min⁻¹，或为久坐健康成年人年龄和性别相关标准值的60%±16%。
卒中后约1个月的运动能力受损。需要进一步研究以阐明这种低运动能力的生理基础。
