Quali-quantitative analysis of adherence and perceived satisfaction of individuals with COPD after high-intensity training on land and in water: additional analysis from a randomized clinical trial

ABSTRACT Although patients with chronic obstructive pulmonary disease (COPD) benefit in many ways after participating in pulmonary rehabilitation programs, high dropout rates are still observed among participants. This study aims to analyze the adherence rate and perceived satisfaction in individuals with chronic obstructive pulmonary disease who underwent high-intensity physical training on land (LG) and in water (WG). This study is an additional analysis from a randomized controlled trial. In total, 36 subjects (51%) completed the intervention. All participants underwent six months of high-intensity endurance and strength training. Adherence was assessed by the proportion of patients who completed the training program. Perceived satisfaction was evaluated using a questionnaire composed of structured and semi-structured questions. The interviews were recorded, transcribed, and analyzed according to the criteria of our thematic analysis. The Shapiro-Wilk test was used to assess data normality, and dropout rates were compared using the chi-square test. Statistical significance was set at 5%. Regarding adherence, 59% of WG participants and 44% of LG participants completed the program, with no difference between the groups (p>0.05). Individuals from both groups were equally satisfied after six months of physical training (
