Effects of Abdominal Breathing,Aerobic Training Combined with Resistance Exercise on Pulmonary Function and Exercise Ability of Elderly Patients with Chronic Obstructive Pulmonary Disease
Objective:To explore and analyze the effects of abdominal breathing,aerobic training combined with resistance exercise on pulmonary function and exercise ability of elderly patients with chronic obstructive pulmonary disease(COPD).Method:A total of 127 elderly patients with COPD treated in Department of Respiratory,Beijing Longfu Hospital from February 2021 to February 2022 were selected,according to the random number table method,they were divided into aerobic exercise group(63 cases)and combined exercise group(64 cases).All patients received routine treatment,the aerobic exercise group received aerobic exercise treatment,and the combined exercise group received abdominal breathing,aerobic training combined with resistance exercise,both were treated continuously for 12 weeks.Pulmonary function,exercise ability,degree of dyspnea,quality of life and airway inflammation indicators[fractional exhaled nitric oxide(FeNO)]were evaluated and compared between the two groups before and 12 weeks after treatment.Result:After 12 weeks of treatment,the levels of forced expiratory volume in one second(FEV1)and forced vital capacity(FVC),and the percentage of FEV1 to FVC(FEV1/FVC%)in both groups were increased than those before treatment,and those in the combined exercise group were higher than those in the aerobic exercise group,the differences were statistically significant(P<0.05).After 12 weeks of treatment,the maximum oxygen uptake(VO2max),anaerobic threshold(AT),and 6-minute walking test(6MWT)results of both groups increased compared to those before treatment,the modified British medical research council(mMRC)score decreased compared to those before treatment,and the improvement of various indicators in the combined exercise group were better than those in the aerobic exercise group,the differences were statistically significant(P<0.05).After 12 weeks of treatment,the COPD assessment test(CAT)and FeNO concentration in both groups decreased compared to those before treatment,and those in the combined exercise group were lower than those in the aerobic exercise group,the differences were statistically significant(P<0.05).Conclusion:Abdominal breathing,aerobic training combined with resistance exercise are more helpful to improve the pulmonary function of elderly patients with COPD,strengthen exercise ability,reduce the degree of dyspnea,improve the quality of life and reduce airway inflammation.
