blood lactate

The concentration of lactates (salts of lactic acid, a product of anaerobic respiration) dissolved in the blood. It is used as a biochemical indicator of anaerobic threshold. Normal concentrations are between 0.7 and 1.8 millimoles per litre. See also lactic acid.

Lactate dissolved in blood. Blood lactate concentration is used as a biochemical measure of the effects of endurance training and as a means of monitoring muscle adaptations. Normal resting values are between 0.7 and 1.8 mm L⁻¹. As a result of training, blond lactate concentrations become lower for the same amount of work.
