The study is a randomized crossover trial testing the feasibility and safety of three different training protocols in 10 COVID-19 survivors that have been discharged from hospital. The subjects will be randomized to perform three different exercise training protocols in a random order.~The aim is to clarify the feasibility and safety of three training protocols in COVID-19 survivors. The hypothesis is that patients surviving COVID-19 will be able to comply to all training protocols.~The study consists of 4 visits with 1 baseline session (a medical screening and fitness test) and 3 different training sessions. Each training is separated by 1-week washout, to account for potential confounding by leisure activity performed just before the training, patients will be wearing activity watches (Polar).~Feasibility and safety evaluation will be based on 1) how tolerable and enjoyable the training was based on a subjective questionnaire (Likert Scale) 2) compliance to the prescribed exercise protocol with regard to duration and intensity and 3) experienced side effects.
This current protocol encompasses an investigator-blinded randomized exercise intervention in 10 COVID-19 survivors that have been discharged from hospital. The subjects will be randomized to perform three different exercise training protocols in a random order.~The aim is to clarify the feasibility and safety of three training protocols in COVID-19 survivors. The hypothesis is that patients surviving COVID-19 will be able to comply to all training protocols.
