Biography and career

Pre-Bangkok career

Kwamsawat was born on March 20, 1971 in Ubon Ratchathani province. He first discovered Muay Thai by watching fights on television and later started training with the encouragement of his older brother. His initial training began at age 7 in his home. At 16-years-old he joined the Por.Muangubon-Sitlerchai gym located in his local province. He would then begin training under the gym's owner, Kru Pot Wongmuangchan, and became a teammate of award-winning champion Orono Por.Muangubon. He had numerous fights in the Isaan region at 42 kg/92.6 lbs. He would adopt the ring name of Nungubon Sitlerchai.

His ring name "Nungubon" translates to "#1 of Ubon." There are also alternate ways to anglicize Nungubon's ring name such as Neung Ubon Sit Lertchai, Nung-Ubon, Neungubon, etc.

Elite career

Nungubon was an orthodox Muay Femur fighter (rope-a-dope stylist in Muay Thai) who was skilled with punches and kicks from both legs. Nungubon was born with his left leg longer than his right, resulting in the Thai media nicknaming him Tuan Pae (translates to "The Limp" or "The Lame"). Despite this physical abnormality, Nungubon would become an accomplished fighter from 1990 to 1999. In fact, Nungubon's favorite technique was his lead left kick to the body The victories on Nungubon's fight record is filled with championship and award-winning fighters. In particular, he has victories from 8 different Sports Writer's Association Fighter of the Year award winners: Langsuan Panyuthaphum (KO), Kaensak Sor.Ploenchit, Jaroensap Kiatbanchong, Wangchannoi Sor.Palangchai (KO), and others. For context, the Sports Writer's Association Fighter of the Year award is considered in Thailand to be the most prestigious title a Muay Thai fighter can win.

Nungubon's prime lasted from 1990 and 1996, during which he would earn 3 Lumpinee titles in 3 weight classes against elite fighters such as Kompayak Singmanee or Langsuan Panyuthaphum. His 4th and most notable title capture was when Nungubon was past his prime, being visibly slower and less agile as he was matched up against Saenchai in 1999. During this time, Saenchai had entered the peak of his career by winning the highly prestigious Fighter of the Year award and losing no other fight that in 1999 except his first title fight against Nungubon. Nungubon stated that his favorite memory from his career was winning the Lumpinee mini flyweight title (105 lbs/47.6 kg) against Kompayak Singmanee in 1990. Nungubon has stated that the most difficult opponent he ever faced was "The Top Master" Karuhat Sor.Supawan.

Post-retirement

After his fighting career Nungubon opened his own gym named Sit Nungubon in his native province of Ubon Ratchathani. The gym is one of two camps within the same building, the other camp being the Santi Ubon gym which also accepts fighters from the Sit Nungubon gym.
