Movement Analysis

A

s discussed, muscles have the ability to receive and re-

spond to input from the nervous system. The response of

a muscle is either to contract or relax. From a functional

perspective, it is important for the trainer to understand that most

of the muscles of the trunk and extremities have anatomically

opposite muscles. Anatomically, the muscles are arranged in op-

posing pairs.
