dynamic stretching

A lot has been written about the subject of stretching and flexibility in sports. Studies abound on the effects of flexibility on muscular strength, joint motion, and injury prevention, but the picture seems to become more muddled with every passing day, with even the conventional wisdom that static stretching improves flexibility over resistance training recently called into question. But the fact remains: stretching improves flexibility, a foundation for athletic success.

Studies show that a new way of stretching (dynamic stretching) increases power, flexibility and range of motion, and may reduce injuries while the kind of stretching routine most of us have been doing since we were in grade school (holding a stretch for 20 or 30 seconds, supposedly to prepare muscles for exercise, or static stretching) not only fails to do what it is supposed to do but may actually weaken muscles and hurt athletic performance.
