Stretching - Wikipedia, the free encyclopedia |
 | | Stretching is the activity of gradually applying tensile force to lengthen, strengthen, and lubricate muscles, often performed in anticipation of physical exertion and to increase the range of motion within a joint. |
 | | Stretching is also believed to help to prevent injury to tendons, ligaments and muscles by improving muscular elasticity and reducing the stretch reflex in greater ranges of motion that might cause injury to tissue. |
 | | Stretching removes local concentration of excessive lactic acids, that are the biproduct of aerobic action, from the muscle tissue, thus preventing future "cramps", which are a result of tissue damage from the acid build up. |
