Abstract

Introduction: The purpose of this study was to examine the effect of 6 weeks hopping exercises program on time to stabilization and perceived stability in athletes with chronic ankle instability
Methods: twenty-eight basketball player with chronic ankle instability (mean ± SD age;22.67±2.88 years, mean ± SD weight; 80.47±8.48 kg, mean ± SD height; 186.82±3.09 cm) were participated in this study that equally and randomly divided into two following groups: 1) experimental, and 2) control. Time to stabilization in anterior-posterior, medial-lateral direction and ankle joint function assessment tools calculated before and just after exercise program. Descriptive statistic, independed t test and paired sample t test were used to analyze the data. Level of significance was set at α ≤0.05.
Result: The results of the study showed that 6 weeks hopping exercise program had a significant decrease in time to stabilization of medial-lateral and anterior-posterior of ground reaction force and also significant increase in score of ankle joint function assessment tools (P < 0.05).
Conclusion: According the effectiveness of hopping training and also, postural control and time to stabilization deficit in chronic ankle instability population it could be suggested to use these selected exercise in training and rehabilitation
