Abstract

The aim of this study is to examine the correlations between multi directional single leg hop tests (SLHTs) and isokinetic knee strength tests in elite athletes. The study consists of 20 elite male athletes from different branches who were between the ages of 18 and 30. Isokinetic extension (Ex) and flexion (Flx) knee strength tests at different angular velocities (60° 180° and 240°/sec.) and five different SLHTs single hop (SL), triple hop (THD), crossover hop (CHD), medial side triple (MSTH) and 90o medial rotation (MRH) were applied on dominant (DS) and non-dominant (NDS) sides. Paired sample t, One Way ANOVA, Tukey and Pearson tests were used in the statistical analyses of the study. When knee strengths between DS and NDS were compared, significant differences were found at 60°/sec. Ex and Flx and 240°/sec. ex phases in favor of DS (p<0,05). No significance was found when isokinetic tests and limb symmetry index (LSI) obtained from SLHTs were compared (p>0,05). Negative correlations were found between SLHTs and isokinetic tests (p<0,05). It was found that weight and body mass index (BMI) had positive correlations with isokinetic tests and negative correlations with SLHTs (p<0.05). Although our revealed showed that DS and NDS showed strength differences in different measurement methods, both test groups gave reliable results in terms of LSIs. However, expected positive correlations were not found between isokinetic tests and SLHTs, this is thought to be due to the result that weight and BMI had positive correlations with isokinetic tests and negative correlations with SLHTs.
