The purpose of this research is: (a) to compare the dominant and non-dominant leg isokinetic strength and balance, (b) to compare the balance applied on the same side to different directions and isokinetic strength applied to the same side at different angular velocities and (c) to examine the relationship between the balance and isokinetic strength applied at different angular velocities in female volleyball players. Eleven senior female volleyball players voluntarily participated in the research. Isokinetic knee flexion and extension strength were separately obtained on concentric/concentric dominant and non-dominant leg as 5 repetitions at 60 degrees .s [superscript -1] angular velocity, 10 repetitions at 180 degrees .s [superscript -1] and 15 repetitions at 300 degrees .s [superscript -1]. The balance test was performed for both sides in anterior (ANT), posterolateral (PL) and posteromedial (PM) directions. In female volleyball players, there is no significant difference between the dominant and non-dominant leg in terms of isokinetic strength and balance. A significant difference was detected between the balance applied in different directions on the same side and isokinetic force applied at different angular velocities. However, there is not any significant relationship between isokinetic strength and balance in female volleyball players. As a result, there is no isokinetic strength and balance asymmetry in volleyball and there is no relationship between them. This may be an indication of the need for both legs in volleyball.
