COMPARISON OF THE EFFECTS OF KNEE ISOKINETIC MEASUREMENT WITH DIFFERENT POSITION ON KNEE ISOKINETIC STRENGTH

Abstract

The aim of this study was to examine the effect of isokinetic measurements performed in two different positions (prone and sitting) on knee isokinetic strength. For this purpose, 15 healthy sedentary males participated in the study. Isokinetic measurements of the study subjects were made 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 with 600s-1. Each movement 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. According to the result of the research, significant differences were found for 240°s-1, on peak torque (nm) and average power (w) flexion value in favor of the sitting position; 180°s-1, on peak torque (nm), total work (nm) and average power (w) both flexion and extension values in favor of the sitting position; 60°s-1, on peak torque (nm), total work (nm) and average power (w) both flexion and extension values in favor of the sitting position (p < 0.05). As a result, the effect of isokinetic measurements in two different positions on knee isokinetic strength has been significantly revealed. The effect of knee isokinetic measurements in the sitting position on the knee strength is significantly different from the measurements performed prone position.
