Pradip Subramanian, president of the World Bodybuilding and Physique Sports Federation (WBPF) Singapore, had died after his first-ever celebrity Muay Thai bout on Saturday night. He died of a cardiac arrest, according to medical report from a hospital.
Following Subramanian's death, questions have been raised whether he was fully prepared to participate in the fight as a late substitute for former Singapore Idol contestant Sylvester Sim.
He also said that participating in combat sports - even at the level of celebrity bouts - was not something to be taken lightly.
"You need years and years of martial arts training. On top of it - in martial arts - first and foremost is that you need to be able to protect yourself.

"You need to be able to defend yourself before you even think of stepping into competition," he told Channel NewsAsia.
Professional boxing organiser, Ringstar Promotions highlighted the safety protocols it imposes before their fighters are allowed in a ring.
He said that two more doctor's checks are done as part of the safety standards - the first one is carried out on the day of the weigh-in and the second is performed hours before the fight.
Meanwhile, the Amateur Muaythai Association of Singapore (Amas) also said that it had not sanctioned the Thai kickboxing event as they do not have the authority.
CEO of the Singapore Silat Federation, Sheik Alauddin said that in the Pencak Silat, a Southeast Asian ball game, there is a policy of having mandatory medical clearance before allowing competitors to fight.
"In professional fights. Full medical check-ups are needed including brain scans, urine tests, blood tests and even hydration tests before allowing any fighter to fight".
Suggesting that beginners must never be allowed to fight any professional combat sport, Sheik said, "Novice must never be allowed to fight. Theyd have to go through a number of years in amateur fights before being allowed to turn pro...Id say it takes a minimum five years".
Lim also said that novices should wear safety gear.
Sports physician Dr Cormac O'Muircheartaigh said that carrying out medical checks before a fight takes place was essential.
Subramanian's family, meanwhile, said that they were unaware about him taking part in the bout.
"We were initially unaware that he was taking part in the fight. He said went down to watch him fight and did not want to discourage him because he was in his gear and ready to fight," Subramanian, 67-year-old father of the bodybuilder was quoted as saying by The Straits Times.
"He was always passionate about bodybuilding and fitness. He was the youngest in the family, and suddenly he has gone," Shanmugam said.
Subramanian's family members also raised questions over him being allowed to fight.
"We want the authorities to investigate, and are seeking legal advice and getting some lawyers. For now we don't have any plans yet, but maybe tomorrow we will discuss with the other family members and see where we are heading," Subramanian's uncle Roger Rajan was quoted as saying by the newspaper.
