Evolution of longevity in UFC's lower weight classes over past decade

A comprehensive timeline documents how fighters over age 35 have achieved unprecedented success in UFC's lighter weight divisions since 2017. Key milestones include Sara McMann becoming the first fighter in these divisions to win three straight after turning 35 in February 2017, and Lauren Murphy becoming the first to win five straight in June 2021. Amanda Nunes made history as the first to win a title after 35 in June 2023, followed by Alexander Volkanovski in April 2025. Valentina Shevchenko became the first 37-year-old champion in May 2025, with Volkanovski matching that achievement in February 2026. Most recently in April 2026, Raoni Barcelos became the second male fighter after Aiemann Zahabi to achieve a five-fight win streak after turning 35. The data demonstrates increasing competitive longevity in bantamweight, flyweight, and strawweight divisions.
