OBJECTIVE: To investigate the effect of early aerobic training on the aerobic and functional abilities of patients in the subacute stage of cerebrovascular accident (CVA). DESIGN: Randomized controlled trial. SETTING: Rehabilitation unit in Israel. PARTICIPANTS: Ninety-two patients who had a first CVA were randomly assigned to an exercise-training group or to a control group. INTERVENTION: Aerobic training with a leg cycle ergometer for 8 weeks. MAIN OUTCOME MEASURES: Workload, exercise time, resting and submaximal blood pressure and heart rate, and functional abilities. RESULTS: A trend toward improvement was found in all aerobic parameters for the experimental group, but only heart rate at rest (p = 0.02), workload, and work time (p < 0.01) improved significantly. A trend for improvement was also found in all parameters of function for the experimental group, but only stair climbing was significantly better (p < 0.01). An interaction (95% confidence interval 1.7 to 17.21) was found between age and aerobic training on walking distance. Although no significant effect was found in the group of younger patients (aged < 65 y), a significant difference in favor of training was noted in the group of older patients. CONCLUSIONS: Patients with CVA in the subacute stage improved some of their aerobic and functional abilities after submaximal aerobic training.
