Anaerobic Threshold
Short definition
Anaerobic threshold — intensity above which lactate accumulates faster than it is cleared.
Full definition
The anaerobic threshold (AnT, often OBLA at 4 mmol/L) is the intensity at which lactate production exceeds clearance, leading to acidosis. It is an endurance marker: higher AnT (as % of max) means better aerobic fitness.
Examples
Anaerobic threshold at 75 % of max HR.
