Abstract:Objective To compare the effects of centrifugal exercise and air treadmill combined with abdominal breathing training on the exercise ability and cardiopulmonary endurance of patients with stable chronic obstructive pulmonary disease (COPD), and provide more suitable training techniques for the rehabilitation of patients with stable COPD. Methods Ninety-two patients with stable COPD admitted to our hospital from March 2019 to March 2022 were divided into an observation group and a control group by double-blind method. After removing shedding cases, 43 cases in each group were finally included in the study. The observation group received centrifugal exercise training, and the control group received air treadmill + abdominal breathing training. Forced expiratory volume (FEV1) in one second, forced vital capacity (FVC), one-second rate (FEV1/FVC), FEV1 percentage of the expected value (FEV1%pred), maximum autonomous ventilation volume (MVV), maximum oxygen uptake (VO2 max), and maximum oxygen uptake in kilograms (VO2 max), maximum minute ventilation (VEmax), maximum heart rate (HRmax), oxygen pulse (O2/HR), anaerobic threshold (AT), cardiac index (CI), ejection fraction (EF), cardiac output (CO), pulmonary artery pressure (PAP) level were detected in both groups before and 4 weeks after training, respectively. Knee joint motion, walking speed, and creatine kinase (CK) level were recorded before training, 2 weeks after training, and 4 weeks after training. St. George’s Breathing Questionnaire (SGRQ) scores were recorded for both groups before and 4 weeks after training. Results After training, the levels of FVC and MVV were (2.92±0.51) L and (56.81±9.06) L in the observation group, and (2.68±0.53) L and (52.75±9.33) L in the control group, respectively, with statistical significance (t=2.140、2.047, both P<0.05). After training, the VO2 max, VO2 max/kg, VEmax, and AT of the observation group were (1.71±0.42) L, (23.62±4.85) mL/kg, (49.66±9.13) L, and (13.86±3.28) mL/(kg·min), respectively, and those of the control group were (1.53±0.36) L, (21.46±3.52) mL/kg, (45.58±9.25) L, and (15.65±3.89) mL/(kg·min) respectively, with statistical significance (t=2.134, 2.364, 2.059, 2.307, all P<0.05). After training, there were significant differences in CI, EF, CO, and PAP between the two groups (P<0.05). Knee joint motion, walking speed, and CK level in the observation group were (71.48±6.22), (0.75±0.09) m/s, and (206.37±34.45) IU/L, respectively, 4 weeks after training, and those in the control group were (68.59±5.39) °, (0.62±0.22) m/s, and (181.06±39.74) IU/L, respectively, and the differences were statistically significant (t=2.303, 3.586, 3.156, all P<0.05). There were significant differences in respiratory symptoms, mobility, disease impact scores, and total scores between the two groups (all P<0.05). Conclusion Centrifugal exercise training for patients with stable COPD is beneficial to improve their exercise ability and cardiopulmonary endurance, accelerate rehabilitation, and improve their quality of life.
