Nobuaki Kakuda
Although Changpuek would never again quite hit the peak of his success of the early nineties, he fought a number more times with the K-1 organization, the highlight being a victory against Nobuaki Kakuda to claim the W.M.T.C. cruiserweight world title and wins against the likes of Kakuda were tempered by defeats against Michael Thompson, Ivan Hippolyte and Manson Gibson. Changpuek fought a number of fights in Europe around the turn of the millennium winning the W.K.U. world title in 2001 but found victories harder to come by as the toll of career of 300+ fights set in and he retired around 2006 at the age of 40. He currently resides in Pattaya, Thailand where he is the father of two children and is a Muay Thai coach. His nephew, Kongsak Sithboonmee, was named Thailand's top Muay Thai boxer in April 2011.
