History

Historical Context

Chute Boxe Academy began in 1978 when Rudimar Fedrigo opened a Muay Thai gym in Curitiba, later expanding to mixed-martial arts and producing aggressive fighters such as PRIDE champion Wanderlei Silva. The gym’s reputation grew through the late-1990s IVC titles and a 2004 Los Angeles branch. The 2026 death of recent signee Allan Nascimento has revived calls for stricter medical screening in Brazilian MMA gyms.
