Resumen

Nuestro estudio tuvo como objetivo identificar los mecanismos de acción/eliminación del lactato en una situación de ejercicio exhaustivo y monitorear cómo progresa el dolor muscular de aparición tardía (DMT) como resultado del proceso de fatiga metabólica instalado. Se realizaron ejercicios en una caminadora computarizada y en un cicloergómetro durante una clase de Bioquímica del Ejercicio, con recolección de lactato en varios momentos después del ejercicio. Para evaluar DMT, se utilizó una escala de percepción subjetiva de DMT. Hubo un aumento significativo (p<0,001) en la concentración de lactato inmediatamente después del esfuerzo para ambos modelos de ejercicio, con un retorno cercano a los niveles normales 1 hora después del agotamiento. La manifestación del dolor tuvo su pico entre las 24-72 horas posteriores al ejercicio, lo que llevó a los estudiantes a comprender que existen diferentes estrategias de recuperación metabólica después de la realización de ejercicio exhaustivo.
