Abstract
Introduction: Surgical rotations of medical students are physically, emotionally, and intellectually demanding. Energy expenditure throughout a shift, lack of sleep and inadequate nutrition affect student’s performance. --- Objective: The aim of this study is to describe and analyze caloric intake and energy expenditure during a 24-hour shift in medical students during a clinical surgical rotation. --- Materials and Methods: Twenty-three medical students wore a smart armband during a 24-hour shift to register energy expenditure physical activity, along reports of meals and food intake. --- Results: Median energetic expenditure was of 3666 kcal/day while intake was of 1384 kcal/day, averaging a deficit of 2374 kcal. Students slept a median of 0 minutes and walked 9252 steps. Discussion and Conclusion: These parameters should be considered when designing clinical rotations to provide quality service to patients and ensure the well-being of students.
Key words: Caloric expenditure, medical students, Shifts, Clinical Internship

Resumen
Introducción: Las rotaciones clínicas de cirugía de los estudiantes de medicina son exigentes física, emocional e intelectualmente. El extraordinario gasto de energía que se tiene durante un turno quirúrgico, la falta de sueño y una nutrición inadecuada, afecta a los estudiantes de manera profesional y en su vida personal. --- Objetivo: Describir y analizar la ingesta calórica y el gasto energético durante un turno de 24 horas en estudiantes de medicina durante una rotación clínica de cirugía. --- Materiales y métodos: Veintitrés estudiantes de medicina usaron un brazalete inteligente durante un turno de 24 horas con el fin de obtener el gasto de energía, horas de sueño y actividad. Los estudiantes también reportaron cada comida e ingesta de alimentos durante su turno. --- Resultados: La mediana del gasto energético fue de3666 kcal/día y la mediana de ingesta fue de 1384 kcal/día, lo que llevó a un déficit calórico de 2374 kcal. Los estudiantes durmieron una mediana de 0 minutos y caminaron 9252 pasos. Discusión y conclusión:
