Hamstring strains are a significant problem for basketball athletes across levels of play for both sexes. The impact of hamstring muscle strains (HSMS) is significant. Injuries typically result in persistent symptoms and lengthy recovery periods which limit the athlete's practice and play time. Even more significantly, HSMS have high rates of reinjury. It is estimated that approximately one-third of hamstring strains are recurrent. Given the high incidence of HSMS and the substantial tendency for injuries to recur, it has been advocated the greatest impact may be achieved by the development of improved techniques for prevention of initial injury.
