The aim of this study is assessment of correlation between isokinetic muscle strength and muscle thickness. 54 young male athletes (mean age: 18,296 ± 1,312 years, mean height 177,592 ± 5,063 cm; mean body weight 67,037 ± 6,564 kg) playing in the U17 and U19 age groups of a Turkish professional football 1st league team voluntarily participated in the study. Muscle thickness (rectus femoris, vastus intermedius, gluteus maximus) was measured using Real-time ultrasound (RTUS) imaging. Muscle strength (30°/s-1, 60°/s-1, 180°/s-1) was measured using Humac Norm/Cybex dynamometry. Statistically between isokinetic muscle strength and muscle thickness GMAX (mm) - 30°/s-1 Glut Con Torque (N.m-1), RF (mm) - 60°/s-1 Knee Con Torque (N.m-1), VI (mm) - 180°/s-1 Knee Con Torque (N.m-1), RF+VI (mm) - 60°/s-1 Knee Con Torque (N.m-1) values were significantly. In conclusion, this study showed significant and high correlations of quadriceps thickness measurements with muscle strength.
