Lactate threshold. Lactate inflection point (LIP) is the exercise intensity at which the blood concentration of lactate and/or lactic acid begins to increase rapidly. [1] It is often expressed as 85% of maximum heart rate or 75% of maximum oxygen intake. [2] When exercising at or below the lactate threshold, any lactate produced by the muscles ...
Here you can see a typical test where the first lactate threshold is at around 210-215 power output and their second lactate threshold is at 260-265. Courtesy of Human Powered Health Performance Labs
Lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. The conjugate base of lactic acid is called lactate (or the lactate anion).
Anaerobic exercise. Strength training belongs to anaerobic exercise. Anaerobic exercise is a type of exercise that breaks down glucose in the body without using oxygen; anaerobic means "without oxygen". [1] This type of exercise leads to a buildup of lactic acid. [1] In practical terms, this means that anaerobic exercise is more intense, but ...
Ventilatory threshold. In kinesiology, the ventilatory threshold (VT1) refers to the point during exercise at which the volume of air breathed out (expiratory ventilation) starts to increase at an exponentially greater rate than VO 2 (breath-by-breath volume of oxygen (O 2)). [1] VT1 is thought to reflect a person's anaerobic threshold — the ...
He described how to determine the “anaerobic threshold” by using ventilatory and cardiovascular gas exchange responses during exercise testing. Dr. Wasserman defined the “anaerobic threshold” in 1964 as the exercise intensity beyond which the molecule, lactic acid, accumulates in the blood.
Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
Plankton + PHA Flower Acid Algae Serum. Mara's lightweight lotion-like serum refreshes skin in more ways than one. In appearance, it uses lactic acid and PHA to exfoliate and clarify; and in ...
