ABSTRACT
The aims of this chapter are to examine the application of performance indicators in different sports and, using the different structural definitions of games, to make general recommendations about the use and application of these 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 subcategorised by the rules of scoring and of ending the respective matches. These classes are analysed further to enable definition of useful performance indicators and to examine similarities and differences in the analysis of the different categories of game. The indices of performance are subcategorised into general match indicators, tactical indicators, technical indicators and biomechanical indicators. Different research examples and the accuracy of their presentation are discussed. We conclude that, to enable a full and objective interpretation of the data from the analysis of a performance, comparisons of data are vital. In addition, any analysis of the distribution of actions across the playing surface should also be presented normalised, or non-dimensionalised, to the total distribution of actions across the area. Other normalisations of performance indicators should also be used more widely in conjunction with the accepted forms of data analysis.
