摘要

Athletic injury remains inadequately conceptualised and poorly defined. Existing definitions lack the conceptual clarity and logical coherence required to support its maturation into a scientifically meaningful and reliably investigable concept. Related constructs that are often integrated into various operational definitions, such as pain and athlete availability, are frequently conflated as fundamental criteria, producing conceptual instability through semantic vagueness, category conflation, and logical contradiction. These deficiencies in conceptual understanding have hindered the development of precise theoretical and operational frameworks capable of supporting formalisation and have, more broadly, undermined the critical scientific principles of predictability, testability, falsifiability, and reproducibility. To address this, this article employs a systematic process of metaphysical analysis and Carnapian explication, grounded in Aristotelian essentialism and classical logic, to develop a new, scientifically robust theoretical definition of athletic injury. This approach utilises well-established logico-philosophical tools such as thought experiments, boundary tests, and deductive reasoning to evaluate the conceptual coherence of existing definitions, and to establish a set of necessary and sufficient conditions for an athletic injury to exist. Through this process, commonly conflated concepts (Symbebekós, ‘accidental properties’) are examined for logical independence and disentangled from essential properties (To ti ēn einai, ‘what it is to be’), revealing the logical structure that anchors this construct in observation and enables its expression within a coherent, logico-mathematical predictive framework. The outcome is an integrative framework that aligns the theoretical, observational, and mathematical dimensions of athletic injury and associated constructs, such as injury severity, recovery, and rate of recovery, into a unified, formalised system of mathematically defined and interrelated entities for consistent application in mathematical modelling, including prediction, simulation, and causal inference. This paves the way for advancements in the assessment and modelling of athletic injury and related phenomena.
