Abstract
Objective: The aim of this study was to develop a reliable instrument that is capable of rating the players' on-ball match performance using video analysis. Iintroduction: Literature on on-ball match performance is scarce. Instead of providing the coaches with a lot of quantative data, like frequencies of behaviours, we must focus on providing them with information on the quality of their players' match performance. Methods: In collaboration with two expert coaches from s.c. Heerenveen, the instrument was developed through a series of meetings and test analyses. The developed classification includes the following behaviours: receiving the ball; dribbling; passing; one-touch play; heading; moving past an opponent; losing the ball; shots; throw-ins; free kicks and comer kicks. Furthermore, for some of these behaviours, various subcategories were added. In addition, all possible effects that the behaviours can have, were also admitted into the classification. All possible behaviours were rated on a scale from 0 to 5. Intraclass correlation coefficients (ICC) were calculated to assess the intra- and inter-observer reliability of the developed instrument. Results: On average 660 behaviours are rated every match. Most of these behaviours are receivals (199.3) and passes (202.7). The intra-observer reliability ICC was 0.85 (p<O.OO) and the inter-observer reliability ICC was 0.55 (p<O.OO). Discussion and conclusion: Concerning the frequencies of the on-ball behaviours during a single match, the results of this study show great similarities with previous investigations. The intra- observer reliability has proved to be 'good' and the inter-observer reliability is 'moderate'. Proposed adjustments to the classification, the software, and the video footage that is used, will most likely considerably improve the reliability and practical use of the instrument. This instrument can offer soccer coaches several very interesting applications, like monitoring their players' development and guiding the contents of the practice sessions.
