Methods: 35 young football players from the three clubs of Tehran Premier League were randomly divided into three groups: external focus (n=12), internal focus (n =12) and control group (n= 11).The training groups performed pep injury prevention exercises for 8weeks and related instructions instead of warm-up exercises. Before and after the 8-week intervention of EF and IF groups, players performed a jump landing task on the force plate from a 30-cm-high box during which was measured anterior-posterior stability index (APSI), medio-lateral stability index (MLSI), vertical stability index (VSI) and dynamic postural stability index (DPSI) variables. To evaluate the effect of focus of attention on postural stability index variables, repeated-measures ANOVA, one way ANOVA and Tukey post hoc tests were used.
Results: Significant time-by-group interaction effects were found for VSI (P = 0.035) and DPSI (P = 0.036). Although The results of one-way ANOVA test showed no significant different between three groups in pre-test, there was significant different in VSI (P=0.043) and DPSI (P=0.046) between EF and control group in post-test. The EF group showed higher decreases in VSI and DPSI after the 8-week intervention compared with the other 2 groups.
Conclusion: The results show that EF during PEP improves dynamic stability more than IF. Therefore, EF during PEP instructions is preferred to increase the effectiveness of this injury prevention program.
