A total of three people died in Hong Kong over an 11-hour period on Sunday and Monday after exercising. Two had been jogging and one swimming.
The first death was reported at 10pm on Sunday after a 57-year-old man fell unconscious after jogging for an hour with his wife along Ma On Shan Promenade in the New Territories, the Apple Daily reported.
The man, who had a heart disease, was sent to the Prince of Wales Hospital but was pronounced dead on arrival.
At 6am on Monday, a South Asian man was found unconscious on the ground after running on a jogging trail in Victoria Park in Causeway Bay. Other runners called police and the man was sent to hospital but also pronounced dead on arrival.
No identification documents were found on the man and police are making inquiries, Oriental Daily reported.
Two hours later, a 69-year-old local man, a retired civil servant, fell into a coma while swimming in the Ma On Shan public pool. Lifeguards pulled him out of the water and sent him to hospital, but he was later pronounced dead.
Police have not ruled out the possibility that the man may have had heart problems. A doctor told Asia Times that many people are at risk while exercising if they have heart problems like arrhythmia.
