Standard vs Intensive Rehabilitation and Nutrition Regimen for Inpatients at the ICU

Older patients often suffer from multiple illnesses that require acute hospitalization. The goal of medical work is not only to save lives and heal acutely ill people but also to maintain physical fitness and self-sufficiency. In acutely hospitalized patients, the investigators often observe a decrease in muscle mass and strength, a deterioration in overall fitness with the need for long follow-up care, and sometimes permanent help with normal daily activities. An important part of the treatment of every acute patient is the emphasis on adequate nutrition and physical activity. The aim of this study is to determine the most appropriate intensity of exercise and diet that will be best for acute patients and will lead to the maintenance/improvement of physical fitness and thus shorten the length of hospitalization.
