In football games, quantitative evaluation of group sport skills has been an important issue.
In this study, we examined the causal relationship between offensive-defensive performance
and dominant region, which is defined as the area occupied by the team. The dominant
regions of both teams in the team area formed by defense-side positions were calculated for
various plays involving successful and unsuccessful offensive performances. The difference
of the dominant regions between the offensive performances of both teams was then analyzed
statistically. The results showed that the dominant regions of both teams in successful offense
were significantly narrower than those for unsuccessful offense when the turnover position
was located around the middle of the field. This finding indicates that the dominant region is
closely related to offensive performance and suggests that group sport skills that have been
evaluated qualitatively may be evaluated quantitatively in terms of the dominant region.
