摘要
目的:探索个体化有氧联合低水平抗阻运动较单纯有氧运动对老年慢性阻塞性肺病(COPD)患者相关运动能力以及肺功能的影响,并分析其可能机制。方法:招募老年COPD患者40例(男性26例,女性14例),按照随机数表法分为有氧运动组20例,联合运动组20例。两组患者均保持常规药物治疗,给予健康宣教。有氧运动组根据心肺运动试验(CPET)测试评估结果,进行强度为60%—85%目标心率的个体化有氧训练;联合运动组在此基础上增加强度为60%—80%10RM的渐进式抗阻训练,包括腹肌力量训练,下肢弹力带训练,以及根据Breath-link呼吸功能评估与训练系统确定的吸气抗阻训练。训练共12周,每周3—5次,每次30—60min。运动训练前后评测所有患者的肺功能,包括1秒用力呼气量(FEV1),FEV1占预计值百分比(%),用力呼气量占用力肺活量比值(FEV1/FVC%);相关运动能力,包括最大摄氧量(VO_(2max)),无氧阈(AT),6分钟步行能力(6MWT)。结果:两组患者治疗前一般资料及各项指标无明显差异(P>0.05),治疗后有氧运动组患者FEV1、FEV1%、FEV1/FVC%、VO_(2max)、AT、6MWT均有所改善(P<0.05),联合运动组在VO_(2max)、AT、6MWT均有增强(P<0.05),肺功能FEV1、FEV1%、FEV1/FVC%显著改善(P<0.01)。同时,联合运动组各项结果优于有氧训练组(P<0.05)。结论:个体化有氧联合抗阻运动相较于单一有氧训练能够更好地改善老年COPD患者的肺功能和运动能力。
Objective： To observe effects of combined aerobic and low-intensity resistance training versus aerobic training alone on pulmonary function and motor ability in the old patients with COPD and explore the possible mechanism.Method： Forty old patients of COPD were randomly assigned to aerobic training group（AG, n=20） and combined group（CG, n=20）. Both two groups adopted the routine medication management and health education.AG had the aerobic exercises at 60%—85% of target HR which was set according to the cardiopulmonary exercise test（CPET）. CG had the gradually increased resistance training which set intensity at 60%—80% 10 RM（Repetition Maximum） based on the AG. The training included abdominal muscle training, lower limb TheraBand training and inspiratory muscle training with Breath-link Respiratory function assessment and training system. The patients exercised three to five times（30—60 mins per time） a week for 12 weeks. All the patients were evaluated with pulmonary function including forced expiratory volume in 1 second（FEV1）, percentage predicted（FEV1%）, forced vital capacity rate of one second（FEV1/FVC%）. The motor ability including maximal oxygen uptake（VO（2max））, anaerobic threshold（AT）, 6-minute walk test（6 MWT） before and after training.Result： There was no significant difference among the physiology indexes between the two groups before training（P〉0.05）. All the indexes improved in AG after training（P〈0.05）, the indexes of motor ability and pulmonary function improved in varying degree（P〈0.05, P〈0.01 respectively） in CG. Meanwhile, all indexes were better in CG than AG（P〈0.05）.Conclusion： Individualized aerobic training combined with resistance training can give better improvement than aerobic training alone on pulmonary function and motor ability in the old patients with COPD.
