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 ...
This is the intensity at which the heart and lungs can no longer provide adequate oxygen to the working muscles and an oxygen debt begins to accrue; at this point the exercise becomes anaerobic. Aerobic training intensity for most individuals is <85-92% of maximum heart rate. [18]

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]

Exercise regularly Regular exercise is essential for weight loss and long-term health (think: reduced risk of chronic diseases , boosted mood). Physical activity helps burn calories, build muscle ...
During heavy exercise such as long distance running or any demanding exercise, the body's need for oxygen to produce energy is higher than the oxygen supplied in the blood from respiration. Anaerobic metabolism to some degree then takes place in the muscle and this less ideal energy production produces lactic acid as a waste metabolite.
The Mulholland Drive filmmaker, who began smoking at age 8 and quit at 76, says he now needs supplemental oxygen for any physical activity beyond a walk across the room following his 2020 ...
