Table 7 Effects of the training intervention on health-related quality of life in COPD and Healthy, measured using COPD Assessment Test (CAT; COPD-only, n = 20) and the 36-item Short Form Health Survey (SF-36; all participants; n COPD = 20, n Healthy = 57), and assessed as changes from baseline to after completion of the study (per study cluster; CAT and SF-36) and as differential changes between study clusters (SF-36)

From: Chronic obstructive pulmonary disease does not impair responses to resistance training
