Abstract: The aim of the current study was to determine ball velocity and
throwing distance in standing and running throw-in techniques, and to correlate
this performances with isokinetic torques of the, elbow, shoulder, and trunk
extensors and flexors. 14 male amateur soccer players volunteered to
participate to the current study. Concentric Isokinetic tests were measured at
60 and 180°/s angular velocities for elbow and
shoulder, 30 and 120°/s angular velocities for trunk.
Ball velocity was measured by a radar gun and the throwing distance was
measured regarding throw-in performance. Unpaired t-test was used to analyze
ball velocity and throwing distance differences between two different throwing
techniques. To clarify relationship between isokinetic strength values and ball
velocities and distance which occur during two types of throwing techniques
Pearson Correlation Analyze was used. There were no statistical significant
differences regarding throwing velocity and distance between two different
throw-in techniques. Even though, the isokinetic values and throwing velocities
did not correlate with each other, there was a positive correlation between
standing throw-in distance with elbow (non–dominant flexion at 60 and
180°s^{-1}), shoulder (dominant
flexion-extension at 60 and 180°s^{-1}, non-dominant extension at 60 and
180°s^{ - 1}) and trunk (flexion
at 30 and 120°s^{ - 1}). The only
correlation between running throw-in and throwing distance occurred in shoulder
(dominant extension at 60°s^{ -
1}) and trunk (flexion at 30°s^{ -
1}). In conclusion, the isokinetic strength values regarding upper
extremity is strong factor that describes standing throw-in performance.
However; it is not highly correlated with the running throw-in performance in
soccer.
