Hamstring strain injuries (HSI) represent 10-12% of all injuries in professional football (soccer).
The mechanism of injury of HSI is understood to be multifactorial. One association is that it occurs during rapid acceleration/deceleration, where rapid eccentric hamstring contraction is shown to occur. Another well-established link to HSI is a previous history of one.
This prospective cohort study was designed to assess whether pre-season isokinetic strength measures had links to future HSI among professional football players.
