This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To review the evidence from randomised and quasi‐randomised controlled trials evaluating interventions for preventing all types of hamstring injuries in physically active people.

This review aims to compare the effects (primarily the incidence of hamstring injuries) in individuals participating in relevant sport or physical occupations of:
1. interventions targeted at preventing hamstring injuries versus no or placebo intervention;
2. different targeted interventions.

We plan to study the outcomes in different age groups (adolescent versus adult); by history (first time versus recurrent hamstring injury) and participation in professional/ occupational versus leisure activities.
