Effect of 8 Weeks of FIFA 11+ Training on Ground Reaction Force Variables During Single Leg Drop Landing in Young Male Soccer Players

The aim of this study was to investigate the effect of 8 weeks of FIFA 11 training on ground reaction force variables during single leg drop landing in young male soccer players. Twenty-four soccer players aged under 21years old were randomly divided into experimental and control groups. The experimental group underwent 2-month FIFA 11 training. Peak values for the components of Ground Reaction Force were significantly decreased during single leg drop landing in experimental group. In contrast, time to peak of these force variables significantly increased. According to these findings, it can be concluded that FIFA 11 training program may have a positive effect in modifying knee injury risk factors.
