EFFECT OF KNEE ISOKINETIC MEASUREMENT WITH DIFFERENT ANGULAR VELOCITIES ON ISOKINETICS H/Q RATIOS

Abstract

The athlete's injury, performance and follow-up can be interpreted with isokinetic H/Q ratios. The purpose of this study was to investigate the effect of different position (prone and sitting) H/Q ratios in knee isokinetic measurement. For this purpose, 15 healthy sedentary males participated in the study. Isokinetic measurements of the subjects were carried out with Isokinetic dynamometer (CSMI Cybex Humac Norm, USA). Isokinetic measurements were performed in 3 different range of motion (2400s-1 / 1800s-1 / 600s-1). The test was carried out 10 repetitions with 2400s-1 and 1800s-1, and 5 repetitions at 600s-1degrees angular velocities. Each movement angle was performed 45 second rest intervals. SPSS 20.0 package program was used for the analysis of the data. Significance level was accepted as p < 0.05. As a result of the analysis of the data, there was no significant difference between the two positions in the isokinetic H/Q peak torque, total work and average power parameters at an angular speed of 240°s-1 (p > 0.05). At angular velocities of 180°s-1 and 60°s-1, there was a significant difference between two positions in the isokinetic H/Q peak torque, total work and average power parameters (p > 0.05). As a result, the significant difference was determined in favor of the sitting position. In conclusion, it can be said that the isokinetic measurement in different positions has a significant effect on isokinetic knee H/Q ratios
