Rationale: Physical activity (PA) is the main modifiable factor in energy expenditure, and alcohol consumption (AC) could influence patients' quality of life. This study aimed to evaluate the influence of PA and AC on energetic compounds- EC (REE measured by indirect calorimetry-IC, VO2, VCO2, RQ, and REE-IC/kg).
Methods: The study was conduted with 142 non critically ill patients from Hospital São João, Portugal who practiced or did not practice physical activity regularly, and consumed or did not consume alcohol before hospitalization. REE was measured by IC (Cosmed k4 b2). Statistical analysis (SPSS) presented descriptive analysis and the Mann-Whitney U test.
Results: Table 1: Energetic compounds by indirect calorimetry in patients who regularly exercised and did or did not consume alcohol before hospitalization.

Conclusion: Patients who practiced PA showed differences in VO2 consumption, VCO2 production, and REE, and those who AC showed differences in VCO2 production, suggesting increased metabolic activity. Knowing these changes is important to guide clinical practice and nutritional balance, avoiding negatively impact on the prognosis.
