Abstract
Objective data on performance of game players provide a useful basis for monitoring the contributions of individuals towards the team's collective efforts. Notation analysis and motion analysis are different methods of recording patterns of play- and work-rate of players, respectively. These types of observations yield profiles from which sport-specific tests may be designed. Examples are given from soccer, rugby football, and field hockey. The observations are also useful in the design of laboratory-based sports-specific protocols for the design of experimental work. With the rapidly evolving technologies of performance analysis, this area of work is likely to increase in future.
