Do non-contact injuries occur during high-speed running in elite football? Preliminary results from a novel GPS and video-based method.

Objectives: Understanding how injuries occur (inciting circumstances) is useful for developing etiological hypotheses and prevention strategies. The aims of this study were 1) to evaluate the feasibility of a method combining video and Global Positioning System data to estimate the speed and acceleration of activities leading to injuries and 2) to use this method to analyse the inciting circumstances leading to non-contact injuries.

Design: Retrospective descriptive study.
