AbstractsIntroductionThe resistance exercise effect on the exercise ability in chronic obstructive pulmonary disease (COPD) subjects has drawn considerable attention. However, the relationship between resistance exercise and the exercise ability of COPD subjects is conflicting. This meta-analysis was performed to evaluate this relationship.MethodsA systematic-literature search up-to July-2020 was performed in OVID, Embase, Cochrane Library, PubMed, Google scholar for randomized control trials reported relationships between resistance exercise and the exercise ability of COPD subjects, and 13 studies were detected with 1286 subjects at the baseline. Mean differences (MD) with 95% confidence intervals (CIs) were calculated comparing the resistance exercise and the exercise ability of COPD subjects using the continuous method with a random or fixed-effect model.ResultsA significantly higher 6-min walk test was observed in subjects performing resistance training (MD, 60.41; 95% CI, 39.97-80.85, p
