This study included two aims; to compare behavioural momentum between top, middle and bottom netball teams; and to explore the technical and tactical variables that may determine the change in momentum. Twelve Superleague Netball (2017/18 season) matches were analysed with three teams situated top, middle and bottom of the league as a focus. Momentum related events were rated either positively or negatively. Interactive cumulative momentum was calculated and presented in momentum curves following momentum analysis. Height/depth and length of peaks and troughs (mean ± SD) in the curves, net momentum scores and oscillatory frequencies (mean ± SD) were calculated to quantity behavioural momentum. Results indicated Team A as the most successful team with the most positive momentum (5 ±2) and consistency in performance following half time. Chi-squared results on technical and tactical analysis showed significant difference between teams and three other variables (Possession; How; Outcome; p<0.05). Significant associations were also found for How and three other variables (Why, Outcome, Defensive method; p<0.001) and Zone and How (p<0.05). Previous research and coaching literature supported the results. Further research was suggested to investigate the association between location and defensive methods when determining the difference between teams in the league.
