间断负荷训练在稳定期COPD患者运动耐力恢复中的应用效果

Application Effect of Intermittent Load Training on Exercise Endurance Recovery in Stable COPD Patients

【目的】探讨间断负荷训练在稳定期慢性阻塞性肺疾病(COPD)患者运动耐力恢复中的应用效果。【方法】选取2021年6月至2023年9月本院诊治的80例COPD患者,按照随机数字表法分为对照组和观察组,每组40例。对照组采用常规肺康复训练,观察组在对照组基础上加用间断负荷训练。比较两组入院第1天、出院随访12周时患者呼吸困难程度及运动耐力、生活质量评分。【结果】出院随访12周时,观察组呼吸困难问卷(mMRC)等级优于对照组(P<0.05)。两组入院第1天时6 min步行距离(6 minute walking distance,6MWD)比较,差异无统计学意义(P>0.05);出院随访12周时,两组6MWD均远于入院第1天时,且观察组6MWD远于对照组(P<0.05)。两组入院第1天时慢性呼吸问卷(chronic respiratory disease questionnaire,CRQ)各个维度评分比较,差异无统计学意义(P>0.05);出院随访12周时,两组CRQ各个维度评分均高于入院第1天时,且观察组CRQ各个维度评分高于对照组(P<0.05)。【结论】间断负荷训练可改善COPD患者呼吸功能,提高患者运动耐力和生活质量。

【Objective】To investigate the effect of intermittent load training on exercise endurance recovery in patients with stable chronic obstructive pulmonary disease(COPD).【Methods】A total of 80 patients with COPD from June 2021 to September 2023 were selected and divided into the control group and the observation group according to random number table method,with 40 cases in each group.The control group received routine pulmonary rehabilitation training,while the observation group received intermittent load training on the basis of control group.The degree of dyspnea,exercise endurance and quality of life scores were compared between the two groups on first day of admission and 12 weeks of follow-up after discharge.【Results】At 12 weeks follow-up,the dyspnea questionnaire(mMRC)in the observation group was better than that in the control group(P<0.05).There was no significant difference in 6 minute walking distance(6MWD)between the two groups on the first day of admission(P>0.05).At 12 weeks follow-up,the values of 6MWD in both groups was significantly higher than those on the first day of admission,and the 6MWD in the observation group was significantly higher than that in the control group(P<0.05).There was no significant difference in the scores of Chronic respiratory disease questionnaire(CRQ)between the two groups on the first day of admission(P>0.05).At 12 weeks of follow-up,CRQ scores in both groups were higher than those on the first day of admission,and the CRQ scores in the observation group were higher than that in the control group(P<0.05).【Conclusion】Intermittent load training can improve respiratory function,exercise endurance and quality of life in patients with COPD.
