[1] recently summarised the literature regarding obesity as a comorbidity in chronic obstructive pulmonary disease (COPD). Obesity in COPD has been associated with increased symptoms of dyspnoea [2], poorer health-related quality of life [2], increased levels of fatigue [3] and exercise performance limitations, including a decreased tolerance to weight-bearing exercise such as walking [4].We have previously reported the results of a randomised controlled trial examining the effect of water-based exercise in 53 individuals with COPD with physical comorbidities, including obesity [5]. In order to contribute to the discussion on the impact of obesity in COPD we present additional data from the subgroup of 24 obese (defined as body mass index ≥32 kg·m−2) individuals with COPD in our trial. These 24 participants were randomised to either 8 weeks water-based exercise (n=8), land-based exercise (n=8) or control (no exercise) (n=8). Participant characteristics and body composition results are presented in table 1. Within-group comparisons using a paired t-test demonstrated that participants in the water-based exercise group lost the greatest amount of weight over the eight-week period (p=0.02) (table 1). Between-group comparisons using independent group t-tests found a significant difference in change in weight between the water-based exercise group and the control … ER -
