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 ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
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 ...
exercise-induced rhabdomyolysis Exertional rhabdomyolysis ( ER ) is the breakdown of muscle from extreme physical exertion. It is one of many types of rhabdomyolysis that can occur, and because of this, the exact prevalence and incidence are unclear.
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 ...
The steady state oxygen consumption used to define running economy demonstrates the energy cost of running at sub maximal speeds. This is often measured by the volume of oxygen consumed, either in liters or milliliters , per kilogram of body weight per minute (L/kg/min or mL/kg/min). [ 6 ]
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. [1]: 33 [2] [3] Oxygen consumption (VO 2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism.
