Abstract:
Background and Purpose: delay in achieving stability is one of the factors that can cause injury and re-injury in athletes, and because many injuries occur during fatigue, the aim of the present study was to compare the effect of fatigue on the time to stability in the movement of the football head in footballers who have undergone anterior cruciate ligament reconstruction.
Materials and Methods: The present study is quasi-experimental. 24 professional football players participated in the study. 12 healthy active professional football players (control group) and 12 football players participated in this study by reconstructing the anterior cruciate ligament by hamstring graft (experimental group) which took 6 to 24 months to reconstruct. After jumping and crossing an obstacle to a height of 7.5 cm, the participants performed the task of hitting the head and landed on the force plate. These movements were repeated after the fatigue protocol. Information was collected by the force plate (kistler instruments Sweden). MANOVA measurement test at the significant level of P <0.05 was used for comparison between groups.
Results: According to the findings, fatigue affected the time to stability in the internal-external direction (P <0.05), but before fatigue, no difference was observed between the two groups in the internal-external direction. Also, in the anterior-posterior and vertical directions, no significant difference was observed between the two groups when achieving stability before and after fatigue.
Conclusion: It seems that a plyometric fatigue training session can not be effective in differentiating between healthy football players in the anterior-posterior and vertical directions from players who have undergone anterior cruciate ligament reconstruction. However, this difference was observed in the internal-external direction after fatigue.
