The purpose of this study was to examine the peak torque, total work as well as bilateral and reciprocal relation between extensor and flexor muscles of dynamic knee stabilizers. The examinees who took part in this study were students of Faculty of Sport and Physical Education from Sarajevo. 30 of them were active football players and 27 of them were active basketball players. All players had right leg dominant and systematic football as well as basketball activities for about 8 years. The maximal strength of dynamic knee stabilizers was tested at isocinetic equipment (Biodex 3) at angle velocities 60°·s-1 and 180 °·s-1. Taking muscles of dynamic knee stabilizers into consideration, this study proves that there are no significant differences among peak torque and total work as well as there are no significant differences in reciprocal relation between agonist and antagonist muscles of right and left leg. These results indicate that trainings and matches of these football and basketball players during the period of training process influenced equal development of these muscles (bilateral and reciprocal relation).
