  • 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 ( JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif e), oxygen uptake ( JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif o 2), and heart rate (HR) data were collected continuously and expressed as absolute values and relative to values at JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif o 2peak 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 JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif e, JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif o 2, 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 JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif o 2, JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif e, and HR were higher in COPD (≅40% vs 20% of the JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif o 2peak; ≅60% vs 20% of JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif e peak; 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 JOURNAL/jcprh/04.03/01273116-201709000-00011/11FSM1/v/2023-09-11T232137Z/r/image-gif o 2peak, their responses and RPE are comparable with healthy controls.
