Key result
Water aerobic exercise training increased walking distance during the walking distance test and improved respiratory muscle strength, thoracic mobility, and dyspnea in male patients with COPD.
Why the study?
Chronic obstructive pulmonary disease restricts airflow and induces systemic manifestations, prompting evaluation of a water-based aerobic exercise program.

Introduction Chronic obstructive pulmonary disease (COPD) not only restricts airflow but also induces sys-temic manifestations in individuals with the disease. Objective To evaluate the effect of a water-based aero-bic exercise program on respiratory muscle strength, thoracic mobility, dyspnea, and functional capacity in patients with COPD. Methods We conducted a blind randomized controlled trial with 22 patients with COPD, dividing them into a control group (CG) and a training group (TG). The TG participated in 24 sessions of a water aerobic exercise program, while the CG only partici-pated in the evaluations. Maximal respiratory pressure (MRP), dyspnea, and functional capacity were measured. Results When comparing the MRP values (cmH2O) in the pre- and post-training conditions, the results revealed a significant improvement in the TG [maximal inspiratory pressure (MIP): 74.8 ± 15.3 vs. 83.9 ± 17.2; maximal expi-ratory pressure (MEP): 141.5 ± 30.7 vs. 157.6 ± 32.9], whereas no difference was observed for the CG (MIP: 55.5 ± 21.8 vs. 54.4 ± 18.4; MEP: 116.2 ± 40.3 vs. 109.3 ± 38.9). Regarding thoracic mobility in the pre- and post-training conditions, no significant difference was found for the CG, whilst for the TG there was a significant in-crease at the axillary level (cm) (5.9 ± 1.8 vs. 7.7 ± 1.1). With respect to functional capacity, there was a signifi-cant increase in walking distance during the six-minute walking test only in the TG when comparing pre- and post-training conditions (462.1 ± 62.9 vs. 538.5 ± 63.7). Lastly, the dyspnea results demonstrated that after the training period there was a major reduction in the scores of Medical Research Council (3.1 ± 0.8 vs. 1.9 ± 0.7) and Borg CR-10 scales (5.2 ± 0.8 vs. 3.7 ± 0.3) only for the TG. Conclusion The water aerobic exercise training promoted beneficial changes in respiratory mus-cle strength, thoracic mobility, functional capacity and dyspnea among patients with COPD.

Gallo-Silva et al. (2024) conducted an RCT in Chronic obstructive pulmonary disease (COPD) (n=22). Water-based aerobic exercise program vs. Control group (evaluations only) was evaluated on Walking distance during the six-minute walk test (6MWT) at 8 weeks (p=<0.05). Water aerobic exercise training increased walking distance during the walking distance test and improved respiratory muscle strength, thoracic mobility, and dyspnea in male patients with COPD.
