Hyperlactatemia is defined as a persistent, mild to moderate (2-4 mmol/L) increase in blood lactate concentration without metabolic acidosis, whereas lactic acidosis is characterized by persistently increased blood lactate levels (usually >5 mmol/L) in association with metabolic acidosis.
The lactate threshold is basically a measurement of how fit the heart and blood vessels are. With regular exercise training, a personâs lactate threshold goes up. Exercising at an intensity level below the lactate threshold produces very little lactic acid and the body quickly clears what is produced.
