Excess post-exercise oxygen consumption (EPOC, informally called afterburn) is a measurably increased rate of oxygen intake following strenuous activity.In historical contexts the term "oxygen debt" was popularized to explain or perhaps attempt to quantify anaerobic energy expenditure, particularly as regards lactic acid/lactate metabolism; [1] in fact, the term "oxygen debt" is still widely ...
V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...

Oxygen consumption (VO 2) during exercise is best described by the Fick Equation: VO 2 =Q x (a-vO 2 diff), which states that the amount of oxygen consumed is equal to cardiac output (Q) multiplied by the difference between arterial and venous oxygen concentrations. More simply put, oxygen consumption is dictated by the quantity of blood ...
It usually requires undergoing a cardiopulmonary exercise test at your doctor’s office or at an exercise medicine lab, where you wear a mask over your face to record your oxygen consumption and ...
The bulk of the early increase in oxygen consumption after a sudden change in exercise levels results from increased cardiac output. [3] However it has also been found that the increase in the maximal a-vO 2 diff resulting from adaptations to a physical training program can account for most of the difference in VO 2 max in subjects ...
Moderate coffee consumption was linked to the prevention of DNA strand breakage, which studies suggest could also be linked to lower risk of certain diseases, like cancer. 7. Coffee might help you ...
In an incremental exercise test, it is the first speed at which any increase in exercise intensity fails to elicit an increase in oxygen consumption. The vV̇O 2 max of world class middle- and long-distance runners may exceed 24 km/h or 2:30/km pace (15 mph or about 4:00/mile), making this speed slightly comparable to 3000 m race pace.
