Two non-commissioned officers die during physical fitness tests

SEOUL, June 17 (Yonhap) -- Two non-commissioned officers died on Friday due to an apparent cardiac arrest while undergoing separate physical tests, Army officials said.
A 40-year-old warrant officer, identified only by his surname Kang, suddenly collapsed during a 3-kilometer run, part of an annual fitness test at a military base in Cheorwon, about 80 kilometers northeast of Seoul, they said.
Kang was immediately sent to a nearby hospital while performing cardiopulmonary resuscitation, but failed to recover, the officials said.
Also on Friday in Seoul, another 53-year-old command sergeant major, identified by his surname Choi, died during a physical fitness test at the Special Warfare Command, they said.
Choi passed tests of push-ups and sit-ups, but was later found dead with foam coming out of the mouth near the test site as he was apparently warming up for a 3-km run, officials said.
The exact causes of their deaths were being investigated, they said.
