Ballistic Stretching

During ballistic stretching you force the body parts into positions beyond the normal range of motion by the momentum of a swinging movement. It is a quite controversial way of stretching because it may cause injuries. Also the stretching effect itself is questionable since the stressed muscle may tend to contract during the exercise.
