The FIFA 11 programme reduces the costs associated with ankle and hamstring injuries in amateur Spanish football players: A retrospective cohort study.

This study aimed to assess the cost-effectiveness of the "Fédération Internationale de Football Association (FIFA) 11" injury prevention programme for ankle and hamstring injuries. This retrospective cohort study included eighty-four male amateur football players aged 18-40 years. The exposed group performed the FIFA 11 protocol twice a week throughout the 2010-2011 and 2011-2012 seasons; the unexposed group performed the usual training during the 2008-2009 and 2009-2010 seasons.

Clinical benefit of the FIFA 11 programme for the prevention of hamstring and lateral ankle ligament injuries among amateur soccer players.

Objective: To analyse the relationship between the implementation of 'the 11' protocol during the regular season in a men's amateur soccer team and the rate of hamstring and lateral ankle ligament (LAL) injuries, and to estimate the clinical benefit of the programme according to the type of injury and the position field.

Methods: This cohort study was conducted in two different men's amateur soccer teams. During two seasons, the exposed group (43 players) performed 'the 11' protocol twice a week, and the unexposed group (43 players) performed the regular training programme.
