Lactate, the salt of lactic acid, is formed as a degradation product in anaerobic lactic metabolism. Lactate travels via the bloodstream to the liver, heart, kidneys and less stressed muscles to be broken down there. The lactate value in capillary blood can be determined by taking a very small amount from e.g. the earlobe. The lactate value is given in mmol/l.

The resting value is about 0.8 mmol/l. At low load intensities in aerobic glycogen and fat metabolism, lactate values of less than 2 mmol/l are present in the blood. The maximum values that can be reached are around 22 mmol/l lactate.
