Elite women’s rugby has often been analysed using the male performance model as a reference, despite evidence that women’s rugby presents distinct game demands and potentially different risk profiles. This study aimed to compare the frequency of key contact-related events between elite men’s and women’s rugby. An observational, retrospective, comparative cohort study was conducted using official performance data from 135 international matches from the men’s and women’s Six Nations Championships. Variables were grouped into three categories: Open-Play, Static Phases, and Discipline. Independent samples t-tests, Mann–Whitney U tests, and Linear Discriminant Analysis were used to identify sex-based differences. The results showed that men presented a higher frequency of rucks lasting more than 6 s (p < 0.001), whereas no significant differences were found in total tackles (p = 0.378) or total rucks (p = 0.634). In Static Phases, women’s teams recorded significantly more scrums (p < 0.001). In Discipline, women conceded fewer free kicks (p = 0.003) but received more red cards (p = 0.020). In conclusion, elite women’s rugby shares some open-play characteristics with the men’s game but differs in scrum frequency and disciplinary profile, supporting the existence of a distinct contact and risk exposure profile that should be considered when designing training and prevention strategies.
