International Sports Kickboxing Association
World Unified Rules Light Heavyweight Title [81.5kg/179lb] (as of 2026-04-30)
As it is difficult to find comprehensive kickboxing results from the 20th century, these lists are always "under construction." Also this title is controlled by one of those organizations that have world titles in multiple categories such as kickboxing freestyle, K-1 rules, full contact, etc. Because many match results do not specify the category, some of these entries may be for another category. Plus, some kickboxing organizations were known to post the outdated/inaccurate information on their websites especially in 1990's and 2000's. If you have corrections or additional information, please send in!
* Bolded letters in the competitor's name, if any, indicate the surname/family name.
