Abstrakt: Many animals react to threatening stimuli such as a predator attacks by freezing. However, little experimental research investigated freeze response in humans. Here, we have employed practices commonly used in self-defense training to create two unique scenarios simulating armed physical threat. Sixty healthy men volunteers divided into three groups of twenty (untrained, trained but unexperienced, trained and experienced) underwent these scenarios accompanied by measurement of biochemical, physiological, and psychological markers of stress. Our results show that untrained individuals exhibit stronger freezing reactions, while highly skilled participants display the lowest propensity for freezing, especially in high-intensity scenarios. Moreover, the study shows variations in anxiety levels and selected biomarkers, with cortisol and osteocalcin showing different patterns in low and high-intensity scenarios, and suggests a complex interplay between these factors, electrodermal activity, and stress perception.
