AN INVESTIGATION OF KNEE ISOKINETIC TIME TO PEAK TORQUE AND JOINT ANGLE AT PEAK TORQUE: DIFFERENT BODY POSITION EFFECT

Mustafa Burak Cağdanlioğlu, Mustafa Özdal

Abstract


The purpose of study was to investigate the effects of isokinetic knee measurement with different positions (prone and sitting) on knee isokinetic time to peak torque and joint angle at peak torque. For this purpose, 15 health sedentary male participated in the study. Isokinetic measurements were performed with isokinetic dynamometer (CSMI Cybex Humac Norm, USA). Isokinetic tests were performed at 3 different motion angles (60os-1 / 180os-1 / 240os-1). The test was carried out with 10 repetitions at 240os-1and 180os-1 and 5 repetitions at 60os-1. 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. According to the result of the analysis significant differences were found for 240°s-1 on joint angle at peak torque extension parameter in favor of prone position; for 180os-1 on time to peak torque extension and flexion parameter in favor of the prone position; for 60°s-1, on joint angle at peak torque parameter in favor of the sitting position, on time to peak torque extension and time to peak torque flexion parameter in favor of the prone position (p < 0.05). As a result, it can be said that different positions have significant effects on the time to peak torque and joint angle at peak torque in isokinetic knee measurement.
