Fig. 4

Effects of the resistance training intervention on lower-body muscle strength (COPD, n = 18; Healthy, n = 50), lower-body muscle mass (COPD, n = 19; Healthy, n = 47), one-legged endurance performance (COPD, n = 15; Healthy, n = 49) and lower-body muscle quality (COPD, n = 18; Healthy, n = 38) in COPD and Healthy. Each outcome domain is represented by a combined factor, computed from various performance assessments, as defined in the upper panel of the figure and previously described [22]. A presents comparison of overall training effects between COPD and Healthy, measured as relative changes from baseline to after the resistance training intervention (per study cluster; left panel) and as relative and numeric differences in change scores between study clusters (right panels). In these analyses, high- and low-load resistance training (10RM and 30RM, respectively) were combined, warranted by the lack of differences between training load conditions in (B, C). COPD showed greater relative changes in muscle strength and muscle mass than Healthy. B, C presents comparison of effects of 10RM and 30RM resistance training in COPD (B) and Healthy (C) (i.e. per study cluster), measured as relative changes from baseline to after the intervention (left panels) and as relative and numeric differences in change scores between load conditions (right panels). #statistically different effects of resistance training between COPD and Healthy. Data are presented as means with 95% confidence limits
