It is well documented that a systematic individually composed rehabilitation program, including training, has an effect on patients' functional level and quality of life (National board of Health, 2007). Early rehabilitation after hospitalization may break the vicious circle, which can arise for patients with COPD. In this cycle, hospitalization can entail inactivity and loss of muscular strength, thus increasing the risk of new aggravations with re-admittance to hospital as a result (National board of Health, 2014). In addition, at this time no studies examine the effect of training on daily activities (ibid).
