This research aims to define effects of unilateral isokinetic training of a dominant leg on development of peak torque of knee extensor and flexor of physically active female population. Respondents who participated in the research were 30 female students from Faculty of Sport and Physical Education in Sarajevo. They were divided into two groups, an experimental and a control group. Maximum strength of dynamic knee stabilizers was tested on an isokinetic apparatus (Biodex 3) with angular speed of 60°/s and 180°/s. The experimental group conducted additional isokinetic trainings of a dominant leg with angular speed of 60°/s three times a week in the period of four weeks. Obtained results lead to the conclusion that a concentric isokinetic training with angular speed of 60°/s produced significant effects on development of maximum strength of dynamic knee stabilizers of a trained leg and that those results are statistically significally diferent from results of the control group which condusted regular classes.
