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 ]
Aerobic dances are musical fitness routines in which an instructor choreographs several short dance combinations and teaches them to a class. This is usually achieved by teaching the class one to two movements at a time and repeating the movements until the class is able to join the whole choreography together.
Once improvement in aerobic conditioning is apparent, for example in metabolism and oxygen uptake, the body progressively adapts to further training. [20] Aerobic conditioning can be anywhere from walking on the treadmill to mowing the lawn. The average healthy person should engage in 150–200 minutes of moderate aerobic exercise every week.
Certain aerobic exercises can engage large muscle groups, leading to improved muscle definition and increased metabolism even after the workout. Moreover, consistent aerobic exercise enhances ...
Bioenergetic systems are metabolic processes that relate to the flow of energy in living organisms. Those processes convert energy into adenosine triphosphate (ATP), which is the form suitable for muscular activity. There are two main forms of synthesis of ATP: aerobic, which uses oxygen from the bloodstream, and anaerobic, which does not.
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 aerobic energy pathway is the third and slowest ATP producing pathway that is oxygen dependent. This energy pathway typically supplies the bulk of the body's energy during exercise—after three minutes from the onset of exercise until the end, or when the individual experiences fatigue.
Then, there is exercise: As little as taking a walk on a daily basis could help prolong life span, and several studies are now shedding light on the mechanisms through which physical activity ...
