A total of seven studies were included in the review (n at least 4,446; range 195 to 1,538, where stated): four RCTs (quality score 51 to 79) and three CCTs (quality score 26 to 45).
Six studies found that static stretching was ineffective for curbing the incidence of exercise-related injury. One CCT reported significantly fewer lower extremity overuse injuries (p<0.02). Three studies reported significant reductions in musculotendinous and ligament injuries.
