N2  -  Summary. Background. Blood flow restricted (BFR) training represents a new approach to exercise. The angle of peak torque (APT) is the joint angle at which a muscle reaches maximal torque, measured with an isokinetic dynamometer. Time to peak torque (TPT) is the duration until the point above is reached. This study aimed to examine the impact of isokinetic training with BFR on APT and TPT. Methods. The data of two groups of patients who underwent knee concentric exercise on the isokinetic device were utilized. One group consisted of isokinetic exercise combined with BFR and the other group consisted of concentric isokinetic exercise only. The assessments of APT, TPT, and peak torque/body weight (PT/BW) for both knee flexor muscles were conducted using an isokinetic dynamometer at angular velocities of 60º and 180º/sec. Results. Before the implementation of the exercise protocols, no significant difference was observed between the BFR and control groups concerning APT, TPT, and PT/BW values at speeds of both 60º and 180º/sec angular velocities (p>0.05). After the completion of the exercise protocol, the APT of flexion at 60º/sec angular velocity exhibited a more pronounced decline in the BFR group relative to the control group. (p= 0.017). Conclusıons. As BFR can affect different fiber types by different mechanisms, it may have caused a change in APT even though it made no difference to peak torque. This may also signify a comparatively substantial augmentation in the eccentric strength, but further research is needed to confirm these assumptions.
