Purpose: The aims of this study were to facilitate the clinical use of isokinetic strength evaluation of ankle muscles, to provide normative data base for isokinetic measurements of ankle at different velocities and jumping ability of elite athletes who use jumping ability, to provide a source for athletes, coaches and scientific teams by comparing data of elite athletes who do not use jumping ability. Material and method: Thirty elite male volleyball players for study group, thirty elite male wrestling athletes for control group were included in this study. The isokinetic measurements of subjects were evaluated by BIODEX 3 Pro System. Isokinetic measurement of ankle plantar and dorsiflexion in 60 degree/sec, 90 degree/sec, 120 degree/sec, and 240 degree/sec velocities and dorsiflexion / plantar flexion isokinetic peak torque raito (DF/PF) were evaluated. Results: A significant difference was found between the groups in isokinetic plantarflexion peak torque measurements at all velocities (p<0.05). There was no difference between the gropus in isokinetic dorsiflexion peak torque measurements (p>0.05). DF/PF values were lower in volleyball players in all velocities (p<0.05). Conclusion: This study showed that, plantar flexion strength increased, dorsiflexion strength not changed, and therefore, agonist-antagonist muscle balance changed in athletes who use jumping as compared to those not using jumping ability.
