This project presents the first comprehensive historical and statistical analysis of the World Ultimate Full Contact Championship (WUFC), covering 30 consecutive editions held in Portugal between 1988 and 2017. The study integrates historical competition records, institutional archives, and previously published scientific research to examine international participation, competitive performance, and fight-ending patterns in Ultimate Full Contact, Pankration, Free Fight, Vale Tudo, and Mixed Martial Arts (MMA) competition. The documented dataset comprises: • 30 consecutive championship editions (1988–2017) • 689 athlete participations • 346 documented bouts • 39 countries represented • Multiple independent datasets derived from archival records and systematic video-observation studies The analyses include descriptive statistics, Wilson confidence intervals, longitudinal performance assessment, and integration with previously published technical-tactical investigations conducted within the World Ultimate Full Contact Championship. Beyond its scientific contribution, this project serves as an open-access historical archive dedicated to preserving the competitive heritage of the WUFC and documenting the development of full-contact hybrid combat sports in Portugal and the international arena. The project contributes to the preservation, accessibility, and future study of a unique body of competitive combat sport data collected across three decades of international competition.
