A review by Australian researchers concludes studies do not support the notion that stretching before or after exercising benefits young, healthy adults.

   The review, published in the Cochrane Library, found most estimates showed stretching reduced soreness by less than 1 point on a 100-point scale assessing stiffness -- whether or not stretching was performed before or after an activity.

   "The data were remarkably consistent," Herbert said in a statement. "The available evidence suggests that stretching before or after exercise does not prevent muscle soreness in young healthy adults."

   However, the researchers said they believe there is a need to see whether stretching can have an effect on people who have reduced levels of flexibility.
