Abstract
Introduction: The Biodex system is an isolated joint isokinetic system, which allows one to measure the amount of strength produced at different velocity, isokinetic muscle loading consists of fixed speed of movement and variable resistance. Triple hop distance test (THD) is known as a valid predictor of lower limb strength and power. The purpose: the aim of our correlational study is to find the strength of the relation between Isokinetic test, vertical jump and triple-hop distance test as indictors of lower body strength. Methods: 10 male and female athletic college students are selected randomly as the subjects. Their body mass indexes (BMI) ware calculated from height and weight measurements. Isokinetic test, vertical jump (VJ) and triple-hop distance (THD) test were done and the leg dominance was determined by asking the subjects which leg they would use to kick the soccer ball. The SPSS package was used for statistical analysis. Results: we found that relationship between isokinetic tests, vertical jump and triple-hop distance test are low to moderate. The correlation coefficients values was in wide range from r=0.18-0.73 (p< .05). The highest correlation was between knee extension average peak torque 600 & horizontal jump (r=0.731, p <0.5) and the lowest correlation was between VJ and the knee flexion at 3300 (r= -0.335, p<0.5). Conclusion: The relation was moderate to low opposing our hypothesis.
