康复锻炼对慢性阻塞性肺疾病患者心肺运动能力的影响

目的对慢性阻塞性肺疾病(COPD)患者进行康复锻炼,旨在检验康复锻炼能能够提高患者心肺运动能力的假设。方法患者接受为期12周的康复锻炼,每周训练4次,共48次。锻炼结束前进行15min的放松训练。每次锻炼时间约为1.5h。锻炼安排在晨练时间进行。锻炼计划实施前组织患者参加呼吸疾病健康教育,内容包括呼吸技术训练和呼吸肌锻炼。锻炼开始前和结束后分别对患者进行心肺运动能力评定。指标包括最大运动能力、无氧阈、最大摄氧量和6min步行试验(6MD)。结果康复锻炼后与锻炼前比较,患者最大运动能力(t=2.820,P=0.009)、无氧阈(t=2.278,P=0.038)、最大摄氧量(t=2.189,P=0.041)和6min步行试验(t=2.834,P=0.009)差异有显著性或非常显著性意义(P<0.05或P<0.01),心肺运动能力百分数变化差异也有显著意义(P<0.05或P<0.01)。结论康复锻炼可显著提高COPD患者心肺运动能力。

Experimental research on the effect of rehabilitation exercise on cardiopulmonary exercise capacity in patients with chronic obstructive pulmonary disease

Aim To explore the effect of rehabilitation exercise on cardiopulmonary exercise capacity in patients with chronic obstructive pulmonary disease(COPD). Methods Community patients with COPD were organized to perform a twelve week rehabilitation exercise programme, whose main content includes fast walking and jogging.Cardiopulmonary exercise capacity was measured before and after the exercise.Results The maximal exercise capacity, anaerobic threshold,oxygen consumption and six minute walking were significantly improved after rehabilitation exercise than before( P< 0.05 or P< 0.01) .The percentage changes of cardiopulmonary parameters from baseline were also remarkable(P< 0.05 or P< 0.01). Conclusion Rehabilitation exercise can notably improve the cardiopulmonary exercise capacity of patients with COPD.
