In one group, early exercise training (aerobic and strength) during hospitalization for COPD exacerbation followed by exercise training at home until 30 days to discharge and in the other the intervention is usual care. In both group, usual respiratory physiotherapy techniques during hospitalization and adequate physical activity recommendations have been included. The main variable is the increase in moderate or vigorous daily physical activities at 30 days after discharge.
