ABSTRACT
This chapter examines the application of performance indicators in different sports using the different structural definitions, to make general recommendations about the use and application of the indicators. Formal games are classified into three categories: net and wall games, invasion games, and striking and fielding games. The different types of sports are also sub-categorised by the rules of scoring and ending the respective matches. The indices of performance are sub-categorised into general match indicators, tactical indicators, technical indicators and biomechanical indicators. For the different types of games considered, it has become clear that the classification of the different action variables being used as performance indicators follow rules that transcend the different sports. The selection and use of these performance indicators depend upon the research questions being posed, but it is clear that certain guidelines will ensure a more clear and accurate interpretation of these data.
