Chronic obstructive pulmonary disease (COPD) adversely affects the quality of life and life expectancy of patients. Shortness of breath, cough, and fatigue in lower limbs are the main reasons limiting physical activities of patients. The lack of physical activity results in poorer muscle strength. The latest guidelines regarding breathing rehabilitation in COPD patients emphasize a significant role of inspiratory muscle exercises. The objective of the present study was to evaluate the effects of an 8-week long inspiratory muscle training, interval training on a cycle ergometer, and training combining both kinds of rehabilitation, on pulmonary function, health-related quality of life, and the tolerance to exercise in patients with COPD. The study was conducted in a group of 43 patients with diagnosed COPD stage II and III according to GOLD. They were randomly divided into four training groups: inspiratory muscle training (Group 1), cycle ergometer training (Group 2), cycle ergometer and inspiratory muscle training (Group 3), control group - patients who did not participate in any rehabilitation programs (Group 4 - control). Before the rehabilitation process and after its completion the patients were medically examined, they completed a health-related quality of life questionnaire, performed a 6-min walk test, spirometry, and a treadmill exercise test according to the modified Bruce protocol. The results demonstrate a significant improvement in the quality of life measured for Group 3 in comparison with the control group.
慢性阻塞性肺疾病（COPD）对患者的生活质量和预期寿命产生不利影响。呼吸急促、咳嗽和下肢疲劳是限制患者身体活动的主要原因。缺乏身体活动会导致肌肉力量下降。最新的COPD患者呼吸康复指南强调吸气肌锻炼的重要作用。本研究的目的是评估为期8周的吸气肌训练、周期测力计间歇训练以及两种康复训练相结合对COPD患者肺功能、健康相关生活质量和运动耐力的影响。该研究在一组根据GOLD诊断为II期和III期COPD的43名患者中进行。他们被随机分为四个训练组：吸气肌训练组（第1组）、周期测力计训练组（第2组）、周期测力计和吸气肌训练组（第3组）、对照组——未参加任何康复计划的患者（第4组——对照组）。在康复过程开始前和结束后，对患者进行医学检查，他们完成了一份健康相关生活质量问卷，进行了6分钟步行测试、肺活量测定，并根据改良的布鲁斯方案进行了跑步机运动测试。结果表明，与对照组相比，第3组的生活质量有显著改善。
