The purpose of this study is to assess the effect of standard usual care combined with daily supervised physical training during hospitalization with community-acquired pneumonia (CAP) compared to standard usual care alnone.

Community-acuired pneumonia (CAP) is a leading cause of hospitalization worldwide. Despite increased focus on mobilization, hospitalization is associated with bed rest. Bed rest with low levels of physical activity leads to functional deline as well as increased risk of complications.

This study is a randomized controlled trial, which investigates the effect of standard usual care combined with daily supervised physical training in patients hospitalized with CAP compared to standard usual care alone.

Inclusion Criteria:

• Patients 18 years of age or older admitted to hospital with CAP defined as a new infiltrate on chest X-ray/CT and minimum one of the following symptoms: temperature <35˚C or ≥38˚C, cough, pleuritic chest pain, dyspnea, or focal chest signs on auscultation.
• Patients should have an expected admission length of ≥72 hours.
• Patients should be able to move their legs.

Exclusion Criteria:

• Patients unable to give written consent.
• Hospital admission within the last 14 days.
• Severe immunosuppression (cancer chemotherapy ≤28 days, neutropenia ≤1000 cells/μL, ≥20 mg prednisolone-equivalent/day >14 days or other immunosuppressive drugs, HIV infection, former transplant).
