[目的]评价为期8周的家庭下肢力量训练联合全身耐力训练对门诊慢性阻塞性肺疾病（COPD）患者外周肌氧合的影响。[受试者] 8例受试者为COPD患者（6例男性，2例女性）。[方法]采用近红外光谱仪（NIRS）检测干预前后右股外侧肌在静息状态和30%最大随意收缩（MVC）等长收缩时的肌氧合情况。此外，测量了右四头肌的MVC、肌肉耐力时间（TLIM）（定义为从30%MVC的等长收缩开始到测试终止的时间）和增量穿梭行走测试（ISWD）中所覆盖的距离。[结果]干预8周后，MVC、TLIM、ISWD虽有改善，但无明显变化。此外，在干预前后，在休息和肌肉耐力运动期间，NIRS参数没有变化。[结论]肺康复治疗对MVC和步行能力的改善无统计学意义。需要进一步的研究来阐明肺康复对肌肉氧合的影响。
[Purpose] The purpose of this study was to evaluate the benefit of 8-week home-based lower extremity strength training combined with whole body endurance training on peripheral muscle oxygenation in outpatients with chronic Obstructive pulmonary disease (COPD). [Subjects] The 8 Subjects were COPD patients (6 males, 2 females). [Methods] Using near infrared spectroscopy (NIRS), muscle oxygenation in the right vastus lateralis muscle at rest and during isometric contraction of 30% maximal voluntary contraction (MVC) were assessed before and after intervention. Also, MVC of the right quadriceps Muscles, the Muscle endurance time (TLIM), defined as the time from the onset of the isometric contraction of 30% MVC until termination of the test, and the distance covered in the incremental shuttle walking test (ISWD) were measured. [Results] Although there were improvements, no significant changes were seen in MVC, TLIM, and ISWD between before and after the 8-week intervention. Also, no changes were seen in NIRS parameters at rest and during Muscle endurance exercise between before and after intervention. [Conclusion] Our results identify no statistically significant improvements in MVC and walking ability which could be acknowledged as an effect Or pulmonary rehabilitation. Further investigation is needed to clarify the effect Of pulmonary rehabilitation on Muscle oxygenation.
