Expanding normative profiles of elite squash players using momentum of winners and errors.

This paper aims to extend these ideas and explore a new application of these analysis techniques to develop 'momentum profiles' through notational analysis. We defined positive momentum as a player hitting successive winners, negative momentum, as a player hitting errors, and if the player is passive, not hitting winners or making errors, then the player's momentum will stay the same.

With the data processed by the software it was possible to present the 2 sets of data for both players at the same time. It is possible to examine these curves and see where the 'turning points' in the match occurred. For the coach and/or the team psychologist to discuss with the player what happened at these turning points would enhance insight into each respective performance.

This study demonstrates a quantitative, yet qualitative, approach to psychological momentum. Both the world number 1 male and female players have averages of peak length significantly higher than their peers. Further research needs to be done to analyse why their peaks are longer and steeper.
