      摘要 目的：探讨监控下持续靶强度有氧运动对脑卒中合并冠心病患者峰值摄氧量、无氧阈等有氧代谢能力、体质指标及日常生活自理能力的影响。 方法：采用随机分组方法将43例脑卒中合并冠心病患者分为常规康复治疗+常规下肢踏车训练组（A组，21例）、常规康复治疗+监控下有氧运动组（B组，22例），康复治疗8周，常规康复治疗每周5次，每日1次，每日训练时间约2.5h，A组进行常规下肢踏车训练（每周5次，20分钟/次），B组进行监控下持续靶强度有氧运动（每周5次，20min/次），比较A组和B组患者运动治疗前后峰值摄氧量、无氧阈、最大代谢当量、体重、身体质量指数、腹围、日常生活自理能力等指标差异。 结果：第8周末B组患者的峰值摄氧量（16.72±2.19）ml/min/kg、无氧阈（15.40±1.79）ml/min/kg及最大代谢当量（5.07±0.60）明显高于A组；第8周末A组Barthel指数评分（69.1±7.5），B组Barthel指数评分（67.7±4.1），与治疗前相比，两组患者的日常生活自理能力均有提高。第8周末，B组患者腰围（90.36±5.83）cm、体重（64.28±4.57）kg、体重指数（24.02±1.76）kg/m2有明显下降。 结论：监控下持续靶强度有氧运动可以有效改善脑卒中合并冠心病患者的有氧代谢能力和体质指标。

Abstract:

      Abstract Objective: To observe effects of monitoring aerobic exercise with target intensity on the aerobic metabolism capacity (peak oxygen uptake, anaerobic threshold, peak metabolism), physical indicators (weight, BMI and waist circumference) and ability of daily living in stroke patients which combined with coronary artery disease. Method: A total of 43 patients after stroke from the second month to the sixth month which combined with coronary artery disease were randomly divided into general rehabilitation and conventional lower limb treadmill training group (group A, n=21)， general rehabilitation and monitoring aerobic exercise group (group B, n=22). Both group A and group B received 8 weeks general rehabilitation therapy which had five times a week and 2.5 hours a day. Group A got 8 weeks conventional lower limb treadmill training which had five times a week and 20 minutes a day. Group B received 8 weeks monitoring aerobic exercise with target intensity which had five times a week and 20 minutes a day. Compare the difference of peak oxygen uptake, anaerobic threshold, peak metabolism, weight, BMI, waist circumference and ability of daily living between group A and group B before and after a 8-weeks training program. Result: After 8 weeks rehabilitation therapy, patients in group B performed better on peak oxygen uptake, anaerobic threshold, metabolism than those in group A. On the eighth weekend, peak oxygen uptake of patients in group B was 16.72±2.19 ml/min/kg, anaerobic threshold was 15.40±1.79 ml/min/kg, metabolism was 5.07±0.60. On the eighth weekend the Barthel index of patients in group A was 69.1±7.5 and 67.7±4.1 in group B, both are higher than that in 0 week. There was no significant difference of ability of daily living between group A and group B in the eighth weekend. In the eighth weekend, weight of patients in group B was 64.28±4.57kg, BMI was 24.02±1.76kg/m2, waist circumference was 90.36±5.83cm. All of those were lower than those in 0 week. Conclusion: Monitoring aerobic exercise with target intensity can effectively improve the aerobic metabolism capacity and physical index in stroke patients which combined with coronary artery disease.
