The present randomized, single-center, and single-blinded clinical trial tested the hypothesis that tele-supervised home-based exercise training (exercise) is an effective strategy for improving cardiovascular, respiratory, and functional capacity parameters in individuals who were hospitalized due to coronavirus disease 2019 (COVID-19).Thirty-two individuals (52 ± 10 yr; 17 were female) randomly assigned to exercise ( n = 12) or control groups ( n = 20) had their anthropometric (weight, body mass index), hemodynamic (brachial and central blood pressure), vascular (arterial stiffness), ventilatory (pulmonary function and respiratory muscle strength), and functional parameters (handgrip strength, five-time sit to stand, timed up and go test, and 6-min walking test) assessed at baseline (30-45 d of hospital discharged) and after 12 wk of follow-up.Both groups similarly increased ( P0.001) forced vital capacity (absolute and percent of predicted), forced expiratory volume in the first second (absolute and percent of predicted), and handgrip strength during follow-up. However, only the exercise group reduced carotid-femoral pulse wave velocity (-2.0 ± 0.6 m·s -1 , P = 0.048) and increased ( P0.05) resting oxygen saturation (1.9% ± 0.6%), mean inspiratory pressure (24.7 ± 7.1 cm H 2 O), mean expiratory pressure (20.3 ± 5.8 cm H 2 O), and percent of predicted mean expiratory pressure (14% ± 22%) during follow-up. No significant changes were found in any other variable during follow-up.Present findings suggest that tele-supervised home-based exercise training can be a potential adjunct therapeutic to rehabilitate individuals who were hospitalized due to COVID-19.
