The Comparison of Burnout on the Three Directions of Y Test in the Basketball Players with Ankle Instability

Abstract

Abstract:Maintaining dynamic balance in daily activities and desirable sport functions is indeed crucial. The purpose of the present study was to compare the burnout on the three directions of Y test in the basketball players with ankle instability. The subjects in this study Included 28 basketball players who were selectively divided into two groups based on the ankle instability questionnaire. first group (n=16, mean weight 71.31 ± 10.49, mean height 181.75 ± 9.16 cm, mean age 18.12 ± 1.70 years old) were functionally instable on their ankles, the second group (n=12, mean weight 73.66±9.89 kg, mean height 183.25±7.08 cm, mean age 18.41 ± 1.83 years old) were healthy basketball players ." Basketball Movement Specific Circuit" protocol was used to achieve basketball-specific fatigue, and Y test was used to quantify postural control. To make sure that fatigue occurred, Borg scale was employed. The result of dependent T test indicated that dynamic postural control decreased after fatigue in both groups(α<0.005). In addition, the result of the one-way ANOVA demonstrated that there is a statistically significant difference between anterior and posteromedial directions in the group with functional ankle instability and between anterior and posterolateral directions in the healthy group. The results of this study showed that fatigue significantly affected the players with functional ankle instability in posteromedial direction and the healthy players in posterolateral direction.
