Mobility is the ability to perform a joint action through a range of movement.
See the page on muscle movement to find out what happens when you stretch or contract a muscle. The objective of mobility training is to improve the range of stretch of the antagonistic muscles. Mobility plays an important part in the preparation of athletes by developing a range of movement to allow technical development and assisting in the prevention of injury. When you perform a stretch correctly you will feel mild discomfort in the antagonistic muscles. The body responds best to a stretching programme when it is warm and the muscles and joints have been exercised through their current range of movement.
