Should runners stretch before or after a run?

Not to sit on the fence, but it seems that both camps are right to a point. Stretching, when done properly, can decrease the chances of a running injury, provided that it is performed correctly. Incorrectly performed stretches will increase your chances of an injury.

The importance of stretching to any training programme cannot be overstressed. Stretching reduces the risk of injury to the muscles, joints and tendons, and it can improve your all-round performance. Care should be taken when stretching - if you stretch too quickly the muscle can contract and increase tension. Never stretch an entirely cold muscle - only stretch after a warm up. Muscles should always be stretched slowly and the stretch should be held for approximately 30 seconds, this way the muscle tension falls and the muscle can be stretched further.

When stretching don't 'bounce' the muscle! It's a common mistake but bouncing up and down in a stretch can pull or tear the muscle you're trying to ease. Don't stretch if you feel tightness in the muscle or if you feel any pain or discomfort.

Stretching should form part of each an every training session, both before and after, your run. The benefits from stretching correctly can only improve your performance and reduce your chances of picking up a running injury.
