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]
Lactate was essentially payment for ‘oxygen debt’ defined by Hill and Lupton as the ‘total amount of oxygen used, after cessation of exercise in recovery therefrom’. [ 8 ] Cell-cell role of the lactate shuttle
In 1925, A.V. Hill, a Nobel Prize-winning physiologist coined the term “oxygen debt” to describe what happens when individuals exercise with an inadequate supply of oxygen.
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 .
After exercise, “light stretching is OK, as long as you don't reach a point where you're feeling pain,” Behm said. Since your muscles will be warm by that point, overdoing it makes you more ...
A short burst of just about 30 minutes of daily physical activity like brisk walking, cycling to work, or dancing can provide a mental boost to middle-aged people throughout their following day, a ...
