What is the source of energy during aerobic muscle exercise and what is kinetic chain exercise?

Dear Joshua,

Thank you for asking your health related questions. Physical energy for all of the body's activities - whether the action is physical activity such as aerobic exercise, chewing food or the beating of the heart – is generated by the body through the process of metabolism.

Check out the article on What IS metabolism for more information.

(Note: Aerobic exercise is a form of cardiovascular exercise. Cardiovascular exercise improves endurance by helping the heart, lungs and blood circulation functioning in the body. See the article on types of exercise to learn the 4 different types of exercise and how each helps the body in a different way.

The word "kinetic" is an adjective that has 3 definitions:

pertaining to motion

caused by motion

characterized by movement: Running and dancing are kinetic activities.

It comes from the Greek word kinein, which means "to move."

Here is a definition of "kinetic chain exercise" from About.com
(http://backandneck.about.com/od/k/g/kinecticchain.htm)

"In rehabilitation settings such as sports and physical therapy clinics, the body is often viewed as functioning in interconnected segments, for example, your arm, your shoulder, and your spine. The theory behind this is that movement of one part affects the others via a chain reaction. Here is an example:

"When you walk, you step forward with one leg, then bring your trunk over that leg to move ahead. As the leg moves forward, it brings your pelvis on that side with it. In turn, this causes the pelvis on the other side to rotate back. And, your spine turns in response to both the leg and the pelvis as they extend to move you forward in space. This is the kinetic chain in action.

"The term "kinetic chain" is used to describe how you are moving your body. In other words, you can move in either in open kinetic chain or closed kinetic chain. The difference lies in whether the moving part (either your arm or leg) is loose in space or fixed against a hard, unrelenting surface.

"If it is fixed, this is closed kinetic chain movement. It provides resistance back into your trunk. The body parts that the resistance moves through make up the components of the chain. Closed kinetic chain movements provide simultaneous movements of the interconnected segments, and can affect the back."

All the best,
