Lactate Threshold and Anaerobic Threshold (also known as the Onset of Blood Lactate Accumulation OBLA) are very similar and for most intents and purposes are referred to as the same thing. Lactate Threshold is the point at which lactic acid produce in the muscle during glycolysis is not metabolised as fast as it is being produced. Anaerobic Threshold is the result of this Lactate Threshold, after Lactate Threshold occurs the extra lactic acid from the muscle then acuminates into the blood, once Blood Lactate (BL) level reaches 4 mmol/L it is defined as Anaerobic Threshold or OBLA. Additionally, this Lactic acid is then Broken into lactate and acid (H+ ions). The lactate is recycled and used as an energy source, while the H+ ions are neutralised in the blood, with a by-product being CO2, the CO2 then needs to be expelled through ventilation, this is called Ventilatory Threshold (VT) and is characterised by a sudden heavy ventilation. Put simply Lactate Threshold, Anaerobic Threshold and Ventilatory Threshold happen in a cascade chain and each threshold usually occurs soon after the one before it.

What else can I help you with?
When does someone know when their anaerobic threshold has been reached?
Sport scientists use lactate monitoring to deduce a persons anaerobic limit.
How do you calculate the anaerobic threshold?
The anaerobic threshold can be calculated by measuring the point during exercise when the body switches from primarily using aerobic metabolism to anaerobic metabolism. This can be determined through methods such as blood lactate testing or heart rate monitoring to identify the intensity at which lactate levels begin to rise significantly.
What is the relation between lactate threshold and ventilatory threshold?
They both are reached are approx the same time, it is thought to be that the large change (drop) in blood pH when the lactate threshold is reached is causes ventilation to increase rapidly to try and counteract this blood pH change. The lactate threshold itself is just the point at which lactate removal can no longer keep up with lactate production.
Anaerobic Threshold is the point at which aerobic oxygen demands exceed capability true or false?
Anaerobic Threshold is the point at which aerobic oxygen demands exceed capability
What does lactate cause?
Lactate threshold is caused when lactate production exceeds lactate clearance during exercise or increasing intensity.
What is Usain Bolt's lactate threshold?
Usain Bolt's lactate threshold is not publicly specified in exact terms, but it is estimated that elite sprinters like him have a lactate threshold around 85-90% of their maximum heart rate. This high threshold allows them to sustain intense efforts for longer durations before fatigue sets in due to lactate accumulation. Bolt's exceptional speed and endurance during sprints reflect his ability to efficiently manage lactate levels.
What is lthr?
lthr is a lactate threshold heart rate.
Which of the following are true about lactate dehydrogenase?
Correct answer: I, II, III and IV
Is lactate normal as an end product of anaerobic metabolism?
Yes. But we are not supposed to be anaerobic organism and this lactate will eventually converted into to carbon bi oxide and water to give us energy.
What compound is the end-product of anaerobic respiration in exercising muscle citrate or lactate?
Lactate is the end-product of anaerobic respiration in exercising muscle. It is produced when the demand for energy exceeds the supply of oxygen to the muscle cells, leading to the conversion of pyruvate to lactate.
What does the term anaerobic threshold refer to?
it is to describe the phenomenon that takes place in all athletes- namely the maximal speed or effort that an athlete can maintain and still have no increase in lactate. At this speed or effort, lactate levels in the blood remain constant. it is to describe the phenomenon that takes place in all athletes- namely the maximal speed or effort that an athlete can maintain and still have no increase in lactate.

The difference between aerobic and anaerobic glycolysis is?
Aerobic glycolysis requires oxygen to break down glucose into energy, producing a higher yield of ATP. Anaerobic glycolysis does not require oxygen and produces lactate as a byproduct, leading to a lower yield of ATP. Anaerobic glycolysis is used during intense or short-duration activities when oxygen supply is limited.
