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.
What is the relation between lactate threshold and ventilatory threshold?
The lactate threshold is the exercise intensity at which lactate production exceeds clearance, leading to a buildup in the blood. The ventilatory threshold is the point during exercise when ventilation increases non-linearly. These thresholds are related as they both indicate the transition from aerobic to anaerobic energy production, but they can occur at different exercise intensities for an individual.
Why does lactate accumulate in the blood during bursts of very vigorous exercise?
During vigorous exercise, the body may not be able to supply enough oxygen to the muscle cells, leading to anaerobic metabolism. This results in the production of lactate from the breakdown of glucose for energy. The accumulation of lactate in the blood occurs when the rate of lactate production exceeds its removal, leading to an increase in blood lactate levels.
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.
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.

What does the abbreviation LDH mean?
LDH stands for lactate dehydrogenase, an enzyme found in the body that plays a role in the conversion of lactate to pyruvate during energy production. Elevated levels of LDH in the blood can indicate tissue damage or certain medical conditions.
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?
The pathway is called gluconeogenesis, which is the process of synthesizing glucose from non-carbohydrate sources like lactate or amino acids. It occurs mainly in the liver and to a lesser extent in the kidneys.
What blood sample needs to be run within 15 minutes of collection?
The blood sample that needs to be run within 15 minutes of collection is a lactate sample. This is because lactate levels in the blood can rapidly change after collection due to ongoing cellular metabolism, so timely analysis is important for accurate results.
What is the name enzymes that catalyzes the formation of lactate during lactate fermentation?
lactate dehydrogenase
