Descriptor English: Anaerobic Threshold
Descriptor Spanish: Umbral Anaerobio
Descriptor umbral anaerobio
Entry term(s) umbral anaeróbico
Scope note: Nivel de consumo de oxígeno por encima del cual la producción de energía aerobia se suplementa con la de mecanismos anaerobios durante el esfuerzo, lo que conduce a un aumento mantenido de la concentración de lactato y acidosis metabólica. El umbral anaerobio se ve afectado por factores que modifican el suministro de oxígeno a los tejidos, siendo bajo en los cardiópatas. Los métodos para determinarlo son la medición directa de la concentración de lactato y de la concentración de bicarbonato, así como las mediciones del intercambio de gases.

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D015308
Scope note: The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements.
