The determination of isokinetic phase of load range for different joints movement with isokinetic dynamometer

In our study, our aim was to research isokinetic data concerning to actions in different angular velocities with isokinetic dynamometer, searching difference of what proportion its effect on which different joints.Ten males aged 18-24 years, height of 177.6 ± 7.5 centimeters, weight of 72.7 ± 5.1 kilos participated to this study. Twelve joint movements of upper and lower extremity were measured by a Cybex II Norm dynamometer. Two joint movements (one of these from upper and the other is from lower extremity) were measured in one test day. It was provided that the same participant?s coming to test again minimum 24 hours. Each joint movement were repeated three times at defined angular velocities from 30 ? /sec to 450 ? /sec with 30 ? /sec increase interval for each set. Thirty sec resting time was given between sets. The data which was the highest value (in three repetition) assumed as peak tork and used for analysis. It was determined that angular velocities at izokinetic load range from the velocity values of raw data.There was a significant difference between peak torque, work and power values of raw data and calculated peak torque, work and power values of isokinetic load range.For the right analysis of isokinetic dynamometer results: the load range data must be calculated from the raw data which was taken from dynamometer and by this way we can prevent probable errorsKey words: Isokinetic Contraction, Isokinetic Dynamometer, Angular Velocity, Isokinetic Load Range, Pik Tork.
