['There is a growing interest in exercise parameters capable of objectively evaluating the functional capacity of patients with chronic obstructive pulmonary disease (COPD).', 'The purpose of the present study was to analyze breath-by-breath cardiopulmonary and gas exchange recovery responses of patients with COPD after a 6-minute walk test (6MWT).', 'Oxygen uptake (VO2) kinetics of patients were obtained using mobile telemetric cardiopulmonary monitoring during and after a 6MWT. Recovery kinetics were modelled using a 4-parameter nonlinear logistic model. Multiple linear regression was performed to assess the association between the half-time of recovery of oxygen consumption (T1/2 VO2) and exercise capacity (6-minute walking distance, 6MWD).', 'Sixty-nine patients with COPD (28 females) with a mean age of 65 ± 10 years took part in the study. After adjustment for covariates (body mass index, forced expiratory volume in 1 s, forced vital capacity, and age), T1/2 VO2 was significantly associated with 6MWD (p = 0.002).'] Do oxygen Uptake Recovery Kinetics after the 6-Minute Walk Test in Patients with Chronic Obstructive Pulmonary Disease?
