INVESTIGATION OF THE CORRELATION BETWEEN KNEE ISOKINETIC STRENGTH AND STATIC-DYNAMIC LEG STRENGTH

Abstract

The aim of this study was to investigate the correlation between knee isokinetic strength and leg static and dynamic strength in
sedentary subjects. For this purpose, a total of 14 sedentary individuals (22.80 ± 1.48) participated in the study. Isokinetic
measurements of the participants 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). Each movement angle was performed with 15
repetitions and 45 second rest intervals. Static leg strength was measured with a dynamometer. Dynamic leg strength was
evaluated by vertical jump test. SPSS 20.0 package program was used for the analysis of the data. Significance level was
accepted as p < 0.05. According to the results of research, significant correlation negatively between knee isokinetic strength
at 60os-1 angular velocity including total work extension (nm), average power extension (W), time to peak torque values and
dynamic leg strength (p <0.05). No significant correlations between knee isokinetic strength 60os-1 angular velocity including
peak torque flexion (nm), total work flexion (nm), average power flexion (W) and time to peak torque flexion (sec) values
between static leg strength, and no significant correlations was detected between other angular velocity (180os-1 / 240os-1)
between static and dynamic leg strength (p > 0.05). As a result, it can be said that there is a significant correlation negatively
between knee isokinetic strength at 60os-1 angular velocity including total work extension (nm), average power extension (W),
time to peak torque values and dynamic leg strength.
