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.

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 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. At this speed or effort, lactate levels in the blood remain constant.
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.
What is lactate inflection point?
The lactate inflection point refers to the level of physical exertion that an individual experiences when the body begins producing more lactate than it is capable of breaking down. The lactate inflection point can be graphed indirectly by graphing an individual's heart rate relative to some rate of exertion, such as speed or pace. In the context of this graph, the inflection point occurs when the value of the line stops increasing relative to the vertical axis and the slope becomes zero. The lactate infection point occurs when the individual's heart rate ceases to increase along with the increasing level of exertion. Generally, this is the point at which the individual transitions from aerobic to anaerobic metabolism. For most individuals, the duration of time for which anaerobic activity can be sustained is limited and can be measured in minutes (as opposed to hours).
What is the blood Tube color for lactate?
The blood tube color for lactate testing is typically a green or light green top tube, which contains sodium or lithium heparin as an anticoagulant. These tubes are used to prevent clotting of the blood sample during testing for lactate levels.
Are red blood cells aerobic or anaerobic?
Oh, dude, red blood cells are aerobic. They get their energy from oxygen through a process called aerobic respiration. So yeah, they're all about that oxygen life. It's like they're the gym buffs of the cell world, always needing that sweet, sweet O2 to keep them going.
I am exercising well below my anaerobic threshold so why does my face get so red?
This reddening is called erythema and is caused, while exercising or during massage, by the dilation of the blood capillaries under the surface of the skin (epidermis).
What is lactate dehydrogenase?
Lactate dehydrogenase is an enzyme present in the body that plays a key role in converting lactate to pyruvate during energy production. It is found in various tissues, including the heart, liver, muscles, and red blood cells. Elevated levels of lactate dehydrogenase in the blood can indicate tissue damage or disease.
