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 ...
To sustainably lose weight without losing muscle, aim for weight loss of about pound a week—which is a deficit of around 200 to 500 calories a day, depending on your activity level. Talk to a ...
The heart tries to compensate for the energy shortage by increasing heart rate to maximize delivery of oxygen and blood borne fuels to the muscle cells for oxidative phosphorylation. [ 3 ] Without muscle glycogen, it is important to get into second wind without going too fast, too soon nor trying to push through the pain.
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.
The mechanism that allows for this distribution of oxygen to the muscle cells is muscle blood flow. [10] A 20 fold increase of local blood flow within skeletal muscle is necessary for endurance athletes, like marathon runners, to meet their muscles' oxygen demands at maximal exercise that are up to 50 times greater than at rest.

Mastering high-level skills like an olympic weightlifting move or a golf swing may require up to 10,000 hours of practice, but most people can achieve some level of proficiency in far less time ...
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]
“Preserving muscle mass when trying to lose fat is very important. Not only is muscle necessary for normal function, having more muscle mass increases energy expenditure and helps keep weight off.
