lactate threshold
lactate threshold Intensity of exercise above which lactate accumulates increasingly in the blood; traditionally ascribed to shortfall in oxygen supply to muscles, requiring some energy to be supplied by anaerobic metabolism — hence also known as ‘anaerobic threshold’. Recent research challenges this; lactate can be produced by fully-oxygenated muscles, as a result of processes driving the oxidative processes faster. Only above the maximal rate of oxygen uptake does lactate accumulation unequivocally indicate that significant energy is being supplied anaerobically.
