The purpose of this study is to investigate the effects of different types of taping application to functional performancein adolescent volleyball players with functional ankle instability. The Cumberland Ankle Instability Tool was used to select participants, 27 and less than 27 scores were included. Twenty-nine players mean age is 13,49±2,1 were included. Functional performance tests (Single Leg Hop Test, Triple Hop Test, Crossover Hop Test, 6 m. Hop Time Test) were applied to all players according to results control group and taping groups ( kinesiology tape group, dynamic tape group ) were created. Immediately, functional performance test were repeated after kinesiology taping and dynamic taping applied. Statistically no significant difference was found between control groups and both taping groups (p>0,05). When the results of taping and non-taping compared, significant difference was not found (p>0,05). As a result, we may say that taping has no effect to functional performance on players with functional ankle instability. More study is needed about effects of taping to functional performance on athletes with sports injuries.

inclusion criteria: Athletes scoring 27 or below active volleyball players without recent severe lower extremity injuries exclusion criteria: having surgery within six months, ankle injuries in the preceding month. Those scoring above 27, having recent injuries, surgery, or metabolic disorders
