1)One review suggests that there are many beneficial stretches that can improve range of motion (ROM) in athletes, especially runners.[4] 2)Another study found that classic "static stretching" did not prevent injuries for runners.[5] Also, certain stretching techniques and protocols prevent injuries when performed (within 15 minutes) prior to exercise.[6] 3)However, stretching does not prevent delayed onset muscle soreness, neither when performed before nor after exercise, according to a Cochrane review in 2006.[7] 4)It is also suggested that one stretching exercise may not be enough to prevent all types of injury, and therefore, multiple stretching exercises should be used to gain the full effects of stretching.[4] 5)It has also been suggested that proprioceptive neuromuscular facilitation (PNF) stretching yields the greatest change in range of motion, especially short-term benefits.[8] Reasoning behind the biomechanical benefit of PNF stretching points to muscular reflex relaxation found in the musculotendinous unit being stretched.[[url=http://en.wikipedia.org/wiki/Wikipedialease_clarify]clarification needed[/url]] Others[who?] suggest that PNF benefits are due to influence on the joint where the stretch is felt.[[url=http://en.wikipedia.org/wiki/Wikipedialease_clarify]clarification needed[/url]]
