The effects of board training and complex training on ankle stability in taekwondo students with a history of ankle sprain

Abstract Purpose : The purpose of this study is to compare the effects of board training and complex training on ankle stability in taekwondo college students with a history of ankle sprain. Methods : Twenty-seven taekwondo college students were randomly assigned into a board training (BTG, n=9), complex training (CTG, n=9), or control groups (CG, n=9). BTG carried out disk and trampoline training 3 times a week for 8 weeks. CTG carried out resistive and plyometric training 3 times a week for 8 weeks. All subjects completed ankle stability test for static and dynamic balance in anterior/posterior and medial/lateral stability with New Balance System (BIODEX Medical System, USA). Results : There were no significant differences between three groups in ankle stability. Those who participated in BTG significantly improved static balance of left foot in anterior/posterior stability, and dynamic balance of both feet in mediolateral stability, but there were no change in CTG. Conclusion : Board training is more improved ankle stability in taekwondo college students with a history of ankle sprain than complex training.
