The aim of this study was to investigate the correlation between knee isokinetic hamstring / quadriceps (H / Q) ratios and leg static-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, a significant correlation was found between the knee isokinetic H / Q ratios and dynamic leg strength (p < 0.05), while no significant correlation was found between static leg strength (p > 0.05). In conclusion, it can be said that there is a significant correlation between knee isokinetic H / Q ratios and dynamic leg strength.
