Lactate Threshold and “Lactic Acid” in Endurance and Hybrid Performance
Lactate threshold is a key performance marker in endurance and hybrid sports, representing the point where lactate production begins to exceed clearance and sustained intensity becomes difficult. This article explains the physiology behind lactate and metabolic acidosis, clarifies common misconceptions about “lactic acid,” and compares practical field methods for estimating thresholds. It also outlines evidence-based training strategies and shows how lactate dynamics influence performance in hybrid events such as HYROX.
