The present study aims to investigate the relationship between speed and isokinetic knee strength appliedat different angular velocities in female volleyball players. 11 female volleyball players from the seniorcategory volunteered in the study (meanage: 20.2±3.9 years, meanheight: 176.8±7.1 cm, meanweight: 66.6±5.7kg). Isomed 2000 isokinetic dynamometer was used in order to measure the isokinetic strength ofparticipants while 20 m sprint test was conducted in order to measure the speed. In measuring isokineticstrength, knee flexion and extension (H/Q) were measured separately on concentric/concentric dominantand non-dominant legs at 60°/sec angular velocity for 5 repetitions, at 180°/sec for 10 repetitions, and at300°/sec for 15 repetitions. In data analysis, Spearman's correlation test was used for the relationshipbetween isokinetic knee strength applied at different angular velocities and speed (p < 0.05). The highestpeak torque value in participants was measured on both sides at 60°/sec angular velocity. This wasfollowed by 180°/sec and 300°/sec angular velocities respectively. There was no significant relationshipbetween isokinetic knee strength applied at different angular velocities and speed. In conclusion, there isnot any significant relationship between speed and isokinetic knee strength in female volleyball players. |
