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 ...
Aerobic conditioning has the ability to raise maximum oxygen intake, [16] meaning that they are able to diffuse more oxygen into their blood than they previously could. Although exercising at lower intensities improves aerobic conditioning, the most rapid gains are made when exercising close to the anaerobic threshold . [ 17 ]
Aerobic exercise, also known as cardio, is physical exercise [1] of low to high intensity that depends primarily on the aerobic energy-generating process. [2] "Aerobic" is defined as "relating to, involving, or requiring oxygen", [3] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [4]

The available oxygen and energy supply, and disturbances of muscle ion homeostasis are the main factors determining exercise performance, at least during brief very intense exercise. Each muscle contraction involves an action potential that activates voltage sensors, and so releases Ca 2+ ions from the muscle fibre 's sarcoplasmic reticulum .
(Reuters) -A state funeral for Jimmy Carter, the former U.S. president who died on Sunday at the age of 100, will be held at the Washington National Cathedral on Jan. 9, according to the U.S. Army ...
The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...
