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.
Lactic acid is not thought to be a contributor to fatigue in low-moderate intensity activity of any duration. Lactate is an important substrate that can be used during submaximal exercise, recovery and at rest. It is the preferred source of fuel for the heart and brain.Lactic acid or lactate pooling is not the cause of delayed muscle soreness. Lactate accumulation and not necessarily an increase in production, causes an increase concentration of hydrogen ions and corresponding acidosis.Lactate production may actually help to curb the development of acidosis.actic acid is not thought to be a contributor to fatigue in low-moderate intensity activity of any duration.
