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.
What is the differences between anaerobic threshold and lactate threshold?
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 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.

Why do increased hemoglobin levels decrease blood lactate levels?
mmm you spelled that wrong. its hemoglobin, fyi.
What does lactate cause?
Lactate threshold is caused when lactate production exceeds lactate clearance during exercise or increasing intensity.
What is the name of the biochemical pathway describing the conversion of lactate to glucose?
gluconeogenesis or glyconeogenesis. It happens in the cori cicle, for instance - during exercise the muscles use the accumulated glucose to produce energy, producing lactate. Then the lactate goes in the blood stream and is used (mainly) in the liver to produce glucose again
What is the name enzymes that catalyzes the formation of lactate during lactate fermentation?
lactate dehydrogenase
Why does lactate accumulate in the blood during bursts of very vigorous exercise?
Lactate accumulates because of the lack of available oxygen in the muscles. In anaerobic conditions, the pyruvate produced by glycolysis is reduced to lactate via lactate dehydrogenase (while also oxidizing a single molecule of NADH to regenerate NAD+). NAD+ is a very important molecule and must readily be available in the cytoplasm in order for glycolysis to proceed.
