This thesis explores the prevalence, nature and pathogenesis of injuries in boxing. Following an introductory chapter and literature review (Chapters 1 and 2 respectively); Chapter 3 examines injuries in the GB boxing squad from 2005 to 2009. There were a total of 66 boxers on the squad during this period 61% were injured, a total of 297 injuries were recorded. The injury rate in competition was at least 460 times higher than in training, and most injuries were new rather than recurrent (246 v 51). The incidence of concussion is comparatively low compared to other studies in amateur boxing (5 in 5 years). Hand and wrist injuries were the most frequent (23.2%).

Despite increasing public awareness and a growing body of literature on the subject of concussion, or mild traumatic brain injury, an urgent need still exists for reliable diagnostic measures, clinical care guidelines, and effective treatments for the condition. Complexity and heterogeneity complicate research efforts and indicate the need for innovative approaches to synthesize current knowledge in order to improve clinical outcomes. Methods from the interdisciplinary field of systems science, including models of complex systems, have been increasingly applied to biomedical applications and show promise for generating insight for traumatic brain injury.

Glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) have been widely studied and show promise for clinical usefulness in suspected traumatic brain injury (TBI) and concussion. Understanding their diagnostic accuracy over time will help translate them into clinical practice.

Over the last 2 decades, sport-related concussion (SRC) has garnered significant attention. Even with increased awareness and athlete education, sideline recognition and real-time diagnosis remain crucial. The need for an objective and standardized assessment of concussion led to the eventual development of the Sport Concussion Assessment Tool (SCAT) during the Second International Conference on Concussion in Sport in 2004, which is now in its third iteration (SCAT3). In an effort to update our understanding of the most well-known sideline concussion assessment, the authors conducted a systematic review of the SCAT and the evidence supporting its use to date.
