25-year-old NSman who collapsed during HPB exercise session died of coronary artery disease: Mindef, HPB

SINGAPORE — A post-mortem examination of the 25-year-old operationally ready national serviceman (NSman) who collapsed during a Health Promotion Board (HPB) fitness session at West Coast Park last week has found the cause of death to be coronary artery disease.
All FIT@HPB Quick HIIT (high-intensity interval training) sessions remain suspended till further notice as HPB reviews safety practices for its fitness programme, said HPB and the Ministry of Defence (Mindef) in a joint release on Monday (March 7).
The NSman died on March 2 after collapsing while taking part in the event. Resuscitative efforts on him failed.
HIIT is a form of metabolic circuit training that features short bursts of high intensity exercises that build strength, endurance and aerobic fitness over time, according to the NSMatters website.
HPB, Mindef and the Singapore Armed Forces continue to assist the man's family in their time of grief, the statement said.
