Taken from "The Pain-Free Program" by Anthony B. Carey:
When the proper relationship between the two sides [of a joint] is maintained, the joint can move freely through it's designed range of motion (ROM). If the muscle or the connective tissue on one side of the joint pulls more than do those on the other side, which can be caused by muscle imbalances, the proper relationship of the two sides is not maintained. Instead, the range of motion in one direction becomes greater, and the range of motion in the other direction decreases.
Muscle balance. Every muscle in your body exists for a reason. There are no "extras" or accidental misplacements. Each muscle is responsible for specific movements, and each muscle has a counterpart called an antagonist. For every bicep, there is a tricep. In other words, if there is a muscle or muscles that bend the elbow, then there is also a muscle or muscles that straighten the elbow. In proper postural alignment, opposing muscle groups have a mutually respectful arrangement. They maintain an equal degree of pull on either side of a joint, and they share essential information from the nervous system. This allows the joint to move with equal efficiency and freedom in every direction that it is designed to move. The opposite is true if muscles on one side of the joint are dominant. Those muscles would be shorter and tighter. A short, tight muscle will demand more information from the nervous system. This, in turn, inhibits the antagonistic muscle(s) on the other side of the joint. An inhibited muscle will eventually become longer and weaker to allow for the needs of the shorter and tighter muscle. For example, if the muscles of the chest are worked all the time and they become short and tight, they'll inhibit the muscles between the shoulder blades. This pulls the joint that those muscles act upon out of alignment, causing the shoulders to round froward. As mentioned earlier, this will lead to abnormal movement patterns and excessive wear and tear on various structures in the body.
It's not hopeless! There are a series of corrective dynamic stretches and movements that you can do coupled with changes in your daily postural habits that can change these imbalances and have you moving pain free! veryeffectivefitness.com
