Crynodeb
Vallerand et al.’s (1988) antecedents and consequences model states that momentum is triggered by antecedent events. Momentum in netball changes performers’ chances of scoring goals. However, the chance of scoring cannot be directly observed. This makes it difficult to attribute sequences of goals to momentum. The purpose of this study is to simulate momentum in netball to examine the scoring patterns produced. The study was approved by theEthics Committee of the School of Sport and HealthSciences at Cardiff Metropolitan University (PGR-5801).The simulation was for a typical match between teams of similar ability who have a probability of 0.6 of scoring from their own centre pass and 0.5 of scoring from a turnover. It was assumed that the total number of possessions in a match would be an invariant of 160 possessions. Four versions of a simulator were implemented in R to each simulate 10,000 matches. The four versions of the simulator implemented the following momentum effects: (1) No momentum effect, (2) team possessions are effected by goals (probability of the team scoring from its own possessions increases by a probability of 0.1 when they scored the most recent goal, and decreases by a probability of 0.1when the opposition scored the most recent goal), (3) the team’s defence is effected by goals (the probability of the opposition scoring from its possessions decreases by a probability of 0.1 when the team scored the most recent goal, and increases by a probability of 0.1 when the opposition scored the most recent goal), and (4) the team possessions and defence are effected by goals. The inter-quartile ranges for runs of three or more goals overlapped between these four momentum conditions. Thus, it is possible that observable events may suggest that there are momentum effects when there is no momentum effect and vice versa. Therefore, observable sequences of events can-not be used on their own to deduce whether performance is influenced by momentum. The simulator also showed that teams are more successful if momentum enhances defence rather than the use of possession. This is because goals often alternate between the teams within netball matches meaning that teams are often defending against centre passes after they have scored.
