There has been a number of studies aiming to establish a relationship between physical, tactical, psychological-type variables and the incidence of sports injuries. The aim of this paper was to assess the influence of anxiety and self-esteem in the development of physical injuries when practising sport. In this regard, the participation of 277 football in this study allowed to record and assess such variables as age, sports injury, field position and anxiety state/trait (measured by the Spielberger, Gorsuch & Lusbene questionnaire). The results did not yield statistically significant differences between the sports injuries and the anxiety state/trait variables (p = 0.583; p = 0.598), nor did they prove a relationship between sports and field position (p = 0.541). As a main conclusion, we advocate the necessity of further studies for the elucidation of such psychological variables which may prevent sports injuries.
