Potential injury incidents are registered, and for each incident the injury location, contact type, player reaction, velocity, location, game reaction, referee reaction, medical staff on pitch, and outcome (e.g. substitution) are also registered.
Simple descriptive statistics are used to create overviews of the outcomes described above, including comparisons between actions which do or do not lead to potential injury incidents.
A secondary analysis may be performed including injury diagnoses, if players consent as part of another study on injury surveillance allowing video analysis of their injuries.
No a priori sample size calculation was performed, as all potential injury incidents are included.
