Heading in Soccer: Does Kinematics of the Head?Neck?Torso Alignment Influence Head Acceleration?

There is little scientific evidence regarding the cumulative effect of purposeful heading. The head-neck-torso alignment considered to be great importance when it comes minimizing potential risks Therefore, this study determined relationship between (cervical spine, head, thoracic spine) and acceleration head maximum ball speed after impact differences accelerations throughout different heading approaches (standing, jumping, running). A total 60 male soccer players (18.9 ± 4.0 years, 177.6 14.9 cm, 73.1 8.6 kg) participated in study. Head were measured by a telemetric Noraxon DTS 3D Sensor, whereas angles for analyzed with Qualisys Track Manager program. No at all was found standing, jumping running approaches. Concerning only standing header significant result calculated (p = 0.024, R<sup>2</sup> .085). difference < .001) identified headers. To sum up, more complex than initially assumed could not proven Furthermore first data generated check whether predictor resulting impact, but further investigations have follow. Lastly, we confirmed results that differs approach.
