Resumen

Objetivo: Conocer los efectos de diferentes intensidades de ejercicio sobre la composición corporal y el consumo de oxígeno. Material y métodos: Se evaluaron 20 sujetos sanos antes y después de un programa de actividad física de 12 semanas de duración en dos grupos; a) moderada intensidad (MI), b) alta intensidad con ejercicios intermitentes (AI). Se midió la circunferencia de la cintura, cadera, composición corporal y consumo máximo de oxígeno. Resultados: La masa grasa (MG) descendió 2,8% en el grupo de MI (p=0,10). La masa muscular aumentó en ambos grupos. El peso corporal no varió significativamente entre grupos. El consumo máximo de oxígeno aumentó en el grupo AI (p< 0,05). El grupo de MI modificó el somatotipo aumentando el componente músculo esquelético. Conclusiones: Los ejercicios de MI produjeron mayor descenso de la MG aunque sin alcanzar significancia estadística. Los ejercicios de AI mejoraron significativamente el consumo de oxígeno. Realizar trabajos mixtos con diferentes intensidades podría producir mayores beneficios para la salud.
