Biomechanics of Ancient Combat Sports: Forensic Applications and Historical Perspectives

The present research studies the multifaceted aspects of ancient combat sports, particularly focusing on Pankration, and extends its findings to modern applications in sports science, rehabilitation, and even forensic investigation. The research employs a multidisciplinary approach, integrating archeological, biomechanical, and forensic methodologies to explore the historical, cultural, and scientific dimensions of these sports. The archaeological research methodologically synthesizes historical texts, artifacts, and mythological narratives, offering a rich tapestry of the combat sports' development from prehistoric times through their classical and Roman evolutions. This historical perspective reveals the deep integration of these sports within the social and cultural fabric of ancient societies, highlighting their symbolic representation of heroism, strength, and divine favor. The study traces the transformation of these sports from mere athletic pursuits to structured competitions, reflecting broader societal shifts. Biomechanically, the research conducts a detailed analysis of the Center of Mass (CoM), Ground Reaction Forces (GRFs), and kinematics of Pankration. These analyses reveal sophisticated strategies for postural stability and efficient movement, with insights into the strategic alignment of the athlete's CoM and symmetrical distribution of GRFs in basic stances. The kinematic study underscores the evolution of Pankration techniques, contrasting ancient forms with modern variants in terms of stance, targeted strike zones, and anatomical focus. The muscle dynamics, explored through Electromyography (EMG), describes the coordination and timing of muscle activation, essential for efficient and effective performance in combat sports. These findings have significant implications for athletic training, emphasizing the importance of personalized training regimens based on individual muscle activation patterns. Statistical approach of the experimental in laboratory analysis included (i) a ANOVA test to examine differences in peak GRF vectors (ii) principal‑component decomposition of time‑normalised three‑dimensional joint‑angle trajectories, with the first three components accounting for 87.2 % of the total kinematic variance; and (iii) a multivariate logistic‑regression classifier, cross‑validated via leave‑one‑athlete‑out resampling, that achieved 94 % overall accuracy in discriminating authentically reconstructed motions from contemporary hybrid analogues. The forensic component of the study investigates the biomechanics of the atlanto-occipital joint, particularly in the context of blunt force trauma. Computational modeling of this joint under varying force magnitudes and damping conditions provides crucial insights into the potential for ligament tearing, critical for forensic evaluations of neck injuries. The study highlights the impact of external factors, such as alcohol consumption, on joint biomechanics, and the risks associated with altered physiological states. Furthermore, this study investigates a differentiation algorithm designed to aid forensic analysis of deceased victims of interpersonal violence. The algorithm's development incorporates an analysis of martial arts and combat sports techniques to ensure robustness in cases involving traditional martial arts (TMA). Concurrently, the concept and necessity of establishing a kinematic and motor skill identity are explored. The implications of this interdisciplinary study are manifold. In sports science, the research informs modern training and rehabilitation strategies, drawing lessons from ancient techniques for performance enhancement and injury prevention. In robotics and mechanical applications, the study's biomechanical insights guide the design of humanoid robots and advanced prosthetics. In forensic science, the findings significantly contribute to understanding and evaluating neck injuries, particularly in trauma and assault cases. In conclusion this study not only enriches our understanding of ancient combat sports and their cultural significance but also bridges these historical practices with modern scientific applications. It underscores the enduring influence of ancient physical cultures across various contemporary fields, from sports science and rehabilitation to forensic investigation and ergonomics.
