World Skate is the current IOC recognised organisational body for roller sports, including skateboarding, rink hockey, inline hockey, inline speed skating, inline alpine, downhill, roller derby, roller freestyle, inline freestyle, Freestyle scootering, aggressive inline skating, inline figure skating and artistic roller skating. The organisation is the result of the merger of the Fédération Internationale de Roller Sports (FIRS) and the International Skateboarding Federation (ISF) in September 2017 after the ISF's involvement with the scheduled skateboarding events at the Japan 2020 Olympics were rejected.
