Ballistic Stretch: This involves dynamic muscle action
where the muscles are stretched suddenly in a bouncing movement.
For example, a ballistic stretch for the hamstrings might involve
touching your toes repeatedly in rapid succession. The problem with
this stretching technique is that rapid stretches invoke a powerful
stretch receptor response that can result in injury. Further, after
you do these exercises, the stretch receptors are overactive. This
may lead to injury during an activity such as running or playing
tennis.
