Proposal of a protocol for the primary prevention of hamstring strains in football players

Hamstring strains, mainly in the femoral biceps, are the most common football injury. In spite of all the studies carried out on preventing these injuries, their incidence has not fallen. One of the possible causes of this is incorrect choice of strength exercises and the traditional reductionist vision that fails to consider the interrelation between risk factors. The aim of this article is to review the risk factors presented in the literature and propose a correct choice of exercises for prevention based on the location of muscle activation, as well as offering a multifactor description of risk factors.
