Objective: Landing is one of the tasks that is performed in many sports skills, and the most common cause of lower limb injuries is in sports in which jumping-landing movements are performed repeatedly. In this situation, fatigue is one of the components that can affect various parameters of the landing movement. Therefore, the aim of this study was to investigate the effect of fatigue on the time to reach stability of female gymnasts with dynamic knee valgus during the landing task.
Research method: The current research was semi-experimental with a pre-test-post-test design. For this purpose, 21 female gymnasts with dynamic knee valgus were selected through targeted and accessible sampling. The time to reach stability in these people before and after the fatigue protocol was measured by force plate device. SPSS version 25 software and dependent t statistical method were used for data analysis at a significance level of α ≥ 0.05.
Findings: The results of the present research showed a significant difference in the variable of time to reach stability before and after fatigue in the vertical (0.016) and anterior-posterior (0.046) direction. However, no significant difference was observed in the internal-external direction (0.17).
Conclusion: The results showed that plyometric fatigue has a significant difference on the time to reach stability in gymnasts with dynamic knee valgus in the vertical and anterior-posterior directions, and people with dynamic knee valgus are at risk of being vulnerable due to fatigue during landing.
