Skeletal muscles also become aerobically conditioned, as regular aerobic exercise produces a shift in
muscle fibres from more type II (fast twitch/glycolytic) into more type I (slow-twitch/oxidative).
Type I muscle fibres have far more mitochondria than type II, making type I fibres the producers of

Some
neuromuscular diseases recommend regular aerobic exercise (of varying intensities depending on the disease) in order for the skeletal muscles to become aerobically conditioned, providing symptom relief or slowing the course of the disease, for example
metabolic myopathies,
Duchenne muscular dystrophy, and
idiopathic inflammatory myopathies (IIM).
History
Benefits
Aerobic Conditioning has many benefits, including:
* build stronger bones
* improve muscle strength, endurance, and flexibility
* Improve balance
* Increase mental function
* Assist in
weight management and weight loss
* Reduce risk of developing heart disease, hypertension, stroke or diabetes
* Improve lung function
* Lower blood pressure
* Increase HDL ("good" cholesterol)
* Help to manage blood sugar
Cardiovascular conditioning
Aerobic conditioning trains the heart to be more effective at pumping blood around the body,
it does this in a multitude of ways:
* Increasing the stroke volume of the heart (how much blood the heart is pumping per beat)
* Increasing the diameter of the blood vessels, which allows for more blood to move through the body, which in turn allows for more oxygen to diffuse into muscle cells.
* Increasing the size of the heart chambers, enlarging the heart so it can hold and pump more blood.
Maximum oxygen intake (Vo2)
Aerobic conditioning has the ability to raise maximum oxygen intake, 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. 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.
Recommendations
Aerobic conditioning has many benefits to overall health as it can increase physical endurance and lifespan. Once improvement in aerobic conditioning is apparent, for example in metabolism and oxygen uptake, the body progressively adapts to further training.
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. This amount of
physical activity helps with maintaining a healthy
weight
In science and engineering, the weight of an object is a quantity associated with the gravitational force exerted on the object by other objects in its environment, although there is some variation and debate as to the exact definition.
