The impact of FIFA 11+ exercise program on isokinetic muscle strength and balance on adolescent amateur soccer players

This study was carried out for a 9 weeks period in order to apply F 11+ football injury prevention program on an adolescent age group amateur football team and to enquire the impacts of it on muscle strength and balance. The footballers of a team from Turkey's Super Amateur League (N = 24) were included in the research. F 11+ exercise program was conducted for the study group for 9 weeks in addition to the routine training program. Control group continued routine program. Isokinetic and balance (SEBT) evaluations of the footballers were made before and after training. As a result of our study, there were not any differences between the groups in terms of age, body weight, height, body mass index values (p> 0.05). In the isokinetic evaluation, the right H / Q ratio at the 60 ° / sec was significantly higher in the control group than the study group (p <0.05) however, no difference was found between the groups after the training (p>0,05). After the training, at the 240 °/ sec, only the left quadriceps peak torque value of the study group was significantly higher than the other group (p <0.05). In isokinetic evaluations, in the comparison of the within groups in before and after training, there were not any significant differences in the other parameters while a difference was found in the right hamstring peak torque value of the study group at the 60 ° / sec and in the ratio of hamstring peak torque value and body weight (p>0,05). As a result of the SEBT, in the post-training comparisons of the groups, study group was found to be significantly higher (p<0,05) in the right anteromedial aspect whereas there were not any differences between the groups in the other aspects (p<0,05) In SEBT evaluation, in the comparisons of the within groups before and after training, there was a significant difference in almost all aspects in the study group (p <0.05) while there were not any differences in the improvement in the control group (p> 0.05). Consequently, it was understood that F 11+ exercise program was singly not effective in muscle strength development in adolescent amateur footballers but it was effective in SEBT balance assessment in some ways. We are of the opinion that this training program will guide the experts who work with amateur footballers lacking a regular training program.
