The anthropometric variables and the static and dynamic balance indices of subjects were evaluated using the Biodex balance assessment tool in three stages: pre-test, post-test, and follow-up (6 weeks after post-test). Subsequently, the training groups performed their relevant exercises for 6 weeks. The repeated-measures analysis of variance and Bonferroni post-hoc test were used for the statistical analyses. The significance level was considered <0.05.<br> <strong>Results</strong>: The repeated-measures ANOVA results showed that the static and dynamic balance indices of the subjects in the training groups significantly improved from the pre-test to the post-test (P&le;0.05). Additionally, the results indicated that 6 weeks after the post-test stage, the positive effects of wobble board and TRX training did not diminish in either training group (P&le;0.05). However, the balance indices evaluated in the control group did not show any significant difference at any of the measurement points (P&ge;0.05).&nbsp;<br> <strong>Conclusion</strong>: Athletes with functional ankle instability often struggle with deficiencies in both static and dynamic balance, which increases their vulnerability to re-injury during dynamic movements. Our findings suggest that incorporating functional-based approaches, such as wobble-board and TRX exercises, can serve as effective strategies for enhancing balance in athletes with functional ankle instability.</div> Wobble-Board Training, TRX Training, Functional Ankle Instability, Balance 39 48 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-545-1&slc_lang=en&sid=1 Mohammad kalantariyan m.kalantar@sru.ac.ir or, mkalantar1989@gmail.com 0000-0001-9048-5010 Yes Department of Sport Injury and Corrective Exercises, Faculty of Sport Sciences, Shahid Rajaee Teacher Training University, Tehran, Iran.
