We examined the effect of arm and leg exercise training on ventilatory muscle performance in 15 patients with symptomatic COPD. Eight patients trained their arms while seven trained their legs for six weeks. Before and after the training we measured exercise and pulmonary function including the maximal sustained ventilatory capacity (MSVC). After training there was no significant change in spirometric values and lung volumes. The mean endurance workload performed for 20 minutes increased significantly in both the arm and leg trained groups (14.4 +/- 2.4 to 24.8 +/- 2.5 W, P less than 0.01, and 26.1 +/- 2.4 to 44.4 +/- 2.5 W, P less than 0.01, respectively). Despite the increase in endurance, no significant change was noted in the MSVC (46 +/- 5 to 51 +/- 5 for the arm trainers and 36 +/- 2 to 39 +/- 1 for the leg trainers). We conclude that nonventilatory muscle exercise such as arm and leg cycling does not improve ventilatory muscle endurance, and that increased exercise endurance may occur independent of changes in ventilatory muscle endurance.
我们研究了手臂和腿部运动训练对15例有症状的慢性阻塞性肺疾病(COPD)患者通气肌肉功能的影响。8例患者训练手臂,7例患者训练腿部,为期6周。在训练前后,我们测量了运动和肺功能,包括最大持续通气能力(MSVC)。训练后,肺量计值和肺容积无显著变化。在手臂训练组和腿部训练组中,进行20分钟的平均耐力工作量均显著增加(分别从14.4±2.4瓦增加到24.8±2.5瓦,P<0.01;从26.1±2.4瓦增加到44.4±2.5瓦,P<0.01)。尽管耐力有所增加,但MSVC无显著变化(手臂训练者从46±5增加到51±5,腿部训练者从36±2增加到39±1)。我们得出结论,诸如手臂和腿部骑行等非通气肌肉运动并不能提高通气肌肉耐力,而且运动耐力的增加可能独立于通气肌肉耐力的变化而发生。
