Epidemiology of hamstring injuries in 538 cases from a (blinded) Multi Sports Club.

In the 17 sports practiced at multi-sport club, the incidence of hamstring injury was 1.29 per 100 athletes per year. Players from sports in which high speed sprinting and kicking are necessary, and amateurs, were at higher risk of suffering a hamstring injury.

Documenting location and the exact tissue involved in hamstring injuries may be beneficial for determining the prognosis and RTP.
