Effects of resistance training on exercise endurance, pulmonary function and quality of life in patients with chronic obstructive pulmonary disease: a Meta-analysis

Abstract

Objective To evaluate the influence of resistance training on exercise endurance, pulmonary function and quality of life in the patients with chronic obstructive pulmonary disease (COPD) . Methods Pubmed, Cochrane Library, Embase, Web of Science, Science Direct, CNKI, VIP, WanFang Database and Chinese biomedical literature database (CBM) were searched for Randomized Controlled Trails (RCT) studying the effects of resistance training in COPD patients from database establishment date to August 2018. Meta-analysis was conducted using Revman 5.3. Results The Meta-analysis result showed that the differences in six-minute walk distance (6MWD) , numbers of turns on 6-minute pegboard and ring test (6PBRT) , forced exhalation volume in one second (FEV1) , the first second forced vital capacity percentage of expected value (FEV1%pre) , forced vital capacity (FVC) , the ratio of the first second forced vital capacity in forced vital capacity (FEV1/FVC%) between resistance training group and control group were statistically significant (P 0.05) . There may be publication bias. Conclusions Resistance training is effective to improve exercise endurance, pulmonary function, while the effects on quality of life is not significant in patients with COPD.
