This study was conducted to determine the relationship between the isokinetic forces of the knee joint flexor
(hamstring) and extensor (m. quadriceps) muscle groups measured at 60° angular velocity, and 10 m to 30 m
linear sprint performance and jump tests (active and squat) at the soccer players. 49 volunteer soccer players
with an average age of 15.65±0.93 years, a mean height of 177.45 ± 7.42 cm, and an average body weight of
70.08±4.31 kg participated in the study. The participants were applied counter movement jump and squat jump
tests, 10 and 30 m sprint tests and isokinetic strength test at 60o/s angular speed. There was no correlation
between 60o/s angular velocity isokinetic force values and jump heights and 10m sprint time (p> 0.05). It was
determined that there was a negative correlation between right and left leg extension peak torque forces and
30m sprint times (p<0.05). It is thought that the peak torque values obtained at low angular velocities used in
isokinetic strength tests do not provide information about the jump and sprint performance of the athletes.
