摘要:Volleyball is adynamic physical game that does not have a definite match duration but is basedon high tempo, quickness, strength, flexibility, endurance and jumping. The aim of this study is to research therelationship between isokinetic knee strength and jumping height in young malevolleyball players. 8 male volleyball players aged between 18-22 participatedin the research voluntarily. In the study, the physicalcharacteristics of the subjects (body height, body weight, body mass index)were determined, vertical jump heights were measured and at low (600/sec)and high (3000/sec) speeds, the right and left kneeflexion/extension concic isokinetic strength test was applied. Data was analyzed with paired sample t-test and Spearmancorrelation coefficient test was used to determine the relationship betweenvertical jump and isokinetic strength (p<0.05).Theright and left knees peak torque of the athletes were compared at low and high angular speeds and nosignificant difference was found. A significant positive correlation wasdetected between the jumping height and the right knee peak torque at lowangular speed (r =.817, p<0.05). This result can be explained by the factthat quadriceps femoris, which is the biggest muscle of the lower extremity, isin the foreground during the jumps that volleyball players perform frequently.It may be advisable to give importance to leg strength training to increase thejump height.
