Nascimento was a Brazilian mixed martial artist who competed in the flyweight division of the UFC, the sport's leading professional promotion. Fighters in this weight class are among the smallest and quickest competitors in the organisation, and Nascimento had been an active member of its roster.
The UFC is the dominant organisation in mixed martial arts, a full-contact combat sport combining striking and grappling disciplines. Deaths of active fighters outside competition are rare and tend to draw significant attention from fans, other athletes and the wider sport, both because of the shock involved and because they raise questions about the health and medical screening of professional combat athletes.
Suspected heart attacks in young, physically fit athletes are unusual and often prompt scrutiny into underlying causes, though such findings typically take time to confirm through medical examination.
