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 an especially important
accompaniment to activities that emphasize controlled muscular strength
and flexibility, such as ballet, acrobatics or martial arts.
Stretching is also believed to help to prevent injury to tendons,
ligaments and muscles by improving muscular elasticity and tone.
In addition, stretching can reduce delayed onset muscle soreness
(DOMS).
There is some controversy over the most effective methods of stretching,
and whether some stretches, such as ballistic, or "bouncing",
stretches, may actually be harmful.
