Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main objective of the present study is to evaluate the differences in the impact of an intervention based solely on physical exercise on the functionality of hospitalized older patients, in an Acute Geriatric Unit, who are malnourished or at risk of malnutrition.

As secondary objectives:

1. To assess and compare changes in body composition following the intervention during hospitalization.
2. To evaluate and compare dietary intake, appetite progression, and food consumption throughout the intervention period.
3. To compare in-hospital infectious complications between the two groups.
4. To describe and compare changes in nutritional biochemical parameters between groups after the intervention and 30 days post-discharge.
5. To study changes in other physical function measures throughout the study period and compare them.
6. To describe the presence of molecular markers related to senescence and sarcopenia in patients and compare them between groups at discharge.
7. To study and compare changes in participants' cognitive status.
8. To evaluate and compare changes in perceived quality of life.
9. To assess and compare changes in maximal dynamic strength before and after the intervention.
10. To describe and compare hospital stays and 30-day readmission rates of study participants.
11. To describe participants' personal satisfaction with the intervention.
12. To describe the presence of potential side effects attributed to the intervention during the study period.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention

Participants included in this group will perform physical exercise

Group Type EXPERIMENTAL

Physical exercise

Intervention Type OTHER

Progressive, supervised multicomponent physical exercise program, including aerobic resistance, strength, and balance training. Strength training for lower limbs (leg press and knee extension) and upper limbs (seated chest press) will be adapted to each individual's functional capacity.

Control

Participants in this group will receive attention from a physiotherapist if needed.

Group Type ACTIVE_COMPARATOR

Usual Care

Intervention Type OTHER

* Hospital physiotherapy for preventing nosocomial disability when necessary.
* Hospital diet modifications appropriate to each participant's clinical situation.
* Oral nutritional supplementation aimed at meeting daily nutritional requirements: 30 kcal/kg body weight, 1.5-2 g protein/kg body weight, 25 g daily fiber.
* Approximate free water intake: women 1.5 L/day, men 2 L/day (unless clinically restricted).
