This is intended to be a bare-bones review of physiology of muscle function. The concepts here have direct application to understanding how specific training improves (or decreases) endurance performance capacity. [Read more…]
Under this section we shall discuss muscles and their functioning, including the various tests that have been done to discover how muscle fibres differ and how they effect performance
In the first inclusion we shall discuss the physiology of muscle function, from its Basic Architecture to its Firing Pattern.
With more to follow…
The Motor Unit
Each fiber of a muscle can contribute to force production only if it is recruited by the brain. One motor nerve can branch into tens, hundreds, or even a thousand branches, each one terminating on a different muscle fiber. One motor nerve plus all of the fibers that it innervates is called a motor unit. A single muscle can consist of hundreds of motor units. [Read more…]
