Impact of Physical Exercise on Hospitalized Older Adults Malnourished or at Risk, With Oral Nutritional Support

The aim of this research is to analyze whether nutritional intervention combined with a multicomponent physical training program based on strength, balance, and aerobic exercises can prevent disability caused during hospitalization in individuals aged 75 years or older admitted for medical conditions, thereby improving functional and cognitive capacity. To achieve this objective, we will conduct a randomized clinical trial in which patients are randomly assigned to either the control group, which does not perform the physical training, or the intervention group, which participates in the multicomponent physical training program.
