PURPOSE
Resistance training is recommended in pulmonary rehabilitation for people with chronic obstructive pulmonary disease (COPD); however, the acute cardiorespiratory responses to different intensities of resistance training are not known. We compared acute cardiorespiratory responses with high-intensity versus low-intensity resistance exercises in persons with COPD and healthy, matched controls. This research may assist in developing training parameters in COPD.
METHODS
Participants (n = 10 per group) performed 1 set of 10 repetitions of leg extension and arm elevation at 2 intensities: 40% (low) and 80% (high) of 1-repetition maximum. Minute ventilation ((Equation is included in full-text article.)E), oxygen uptake ((Equation is included in full-text article.)O2), and heart rate (HR) data were collected continuously and expressed as absolute values and relative to values at (Equation is included in full-text article.)O2peak derived from a cardiopulmonary exercise test. Blood pressure, oxygen saturation, and rating of perceived exertion (RPE) were monitored before and after each set of exercises.
RESULTS
Individuals with COPD showed similar (Equation is included in full-text article.)E, (Equation is included in full-text article.)O2, and HR with high- versus low-intensity exercises. RPE was higher after high- vs low-intensity leg extension (4 ± 1.4 vs 2 ± 1, P < .005) and arm elevation (3 ± 2 vs 1 ± 1.4, P < .005). Compared with healthy participants, relative (Equation is included in full-text article.)O2, (Equation is included in full-text article.)E, and HR were higher in COPD (≅40% vs 20% of the (Equation is included in full-text article.)O2peak; ≅60% vs 20% of (Equation is included in full-text article.)Epeak; and ≅80% vs 20% of HRpeak; all Ps ≤ .004). Absolute responses and RPE were similar between groups, irrespective of intensity and exercise.
CONCLUSION
Immediate cardiorespiratory responses to an acute bout of resistance exercise appear to be independent of the exercise intensity in COPD. Although people with COPD are working closer to their (Equation is included in full-text article.)O2peak, their responses and RPE are comparable with healthy controls.
目的
抗阻训练被推荐用于慢性阻塞性肺疾病（COPD）患者的肺康复；然而，不同强度抗阻训练的急性心肺反应尚不清楚。我们比较了 COPD 患者和健康匹配对照者进行高强度与低强度抗阻运动时的急性心肺反应。这项研究可能有助于 COPD 患者制定训练参数。
方法
参与者（每组 10 人）进行 1 组 10 次腿伸展和手臂抬高运动，强度为 1 次最大重复次数的 40%（低）和 80%（高）。分钟通气量（(Equation is included in full-text article.)E）、摄氧量（(Equation is included in full-text article.)O2）和心率（HR）数据连续采集，并表示为绝对值和相对于心肺运动试验得出的最大摄氧量（(Equation is included in full-text article.)O2peak）的相对值。在每组运动前后监测血压、氧饱和度和感知用力程度（RPE）。
结果
COPD 患者的高、低强度运动时（Equation is included in full-text article.)E、(Equation is included in full-text article.)O2 和 HR 相似。高、低强度腿伸展运动后 RPE 较高（4±1.4 比 2±1，P<0.005）和手臂抬高运动后 RPE 较高（3±2 比 1±1.4，P<0.005）。与健康参与者相比，COPD 患者的相对（Equation is included in full-text article.)O2、(Equation is included in full-text article.)E 和 HR 更高（≅40%比 20%的（Equation is included in full-text article.)O2peak；≅60%比 20%的（Equation is included in full-text article.)Epeak；和 ≅80%比 20%的 HRpeak；所有 P 值均≤0.004）。无论强度和运动如何，绝对反应和 RPE 在两组之间均相似。
结论
急性抗阻运动后即刻心肺反应似乎与 COPD 患者的运动强度无关。尽管 COPD 患者更接近其最大摄氧量（(Equation is included in full-text article.)O2peak），但他们的反应和 RPE 与健康对照组相当。
