| Abstract | ||
| Background: Throwing motion is a sequence of movements generating in the lower quadrant to transfer energy toward the trunk and upper limb. Trunk plays the modulator role to transfer moments into the upper limb. Disruption of one segment affects both proximal and distal segments, and upper limb injury risk may increase. Purpose: the current study was designed to explore the relationship of trunk rotation and throwing arm kinematics. Methods: Ten male healthy handball players participated in the study. Each player's performance was analyzed using 3D motion technology. Data were collected using the semi reality motion system. Pelvic- shoulder separation (amplitude of trunk rotation) and Maximum shoulder external rotation (MER) were investigated for person correlation. Results: There was insignificant correlation between pelvic-shoulder separation and Maximum shoulder external rotation (P= 0.991). Conclusion: Our study results showed that trunk rotation angle was not correlated with throwing arm injuries in healthy colligate handball players. | ||
