High +Gz exposure and extreme head postures reduce range of motion and increase neck pain in fighter pilots. The stiffness decrease suggests a muscular mechanical overload. Findings support the need for targeted neck conditioning and real-time monitoring to mitigate injury risk to sustain operational readiness. Lingscheid R, Nuesse R, Rein R, Goell F, Albracht K, Braunstein B. High +Gz flight reduces cervical 3D kinematics and increases neck pain in fighter pilots.
