00:11Marathon safety issues have once again sparked heated discussions.
00:16The latest case
00:18It happened in South Korea to a 25-year-old.
00:21Running female internet celebrity
00:22This female internet celebrity, Liu Zhiyuan, who usually loves running
00:26She participated in a half marathon last Sunday.
00:29At that time, they were ranked second in the women's group.
00:32When there were only 500 meters left to the finish line
00:34Only then did I realize that I had suddenly lost consciousness.
00:36He collapsed and couldn't get up.
00:37Despite the immediate CPR performed on her by those at the scene...
00:41He was rushed to the hospital for emergency treatment.
00:43He ultimately died tragically.
00:45And this marathon participant
00:47Not your average running enthusiast.
00:49Liu Zhiyuan is not only from the Korea Advanced Institute of Science and Technology
00:52Bloodbath, a researcher in artificial intelligence
00:54He is also a true marathon regular.
00:57She once achieved an amazing time of less than three hours in a full marathon.
01:01So every day I stay in the lab until after 8 pm
01:04They also consistently undergo two hours of long-distance running training.
01:08However, this experienced person
01:11Long-distance runners with excellent physical fitness
01:13But on the half marathon course
01:15His steps have stopped forever.
01:17The exact cause of Liu Zhiyuan's death has not yet been announced.
01:20However, this tragedy also serves as a reminder to everyone.
01:23Cardiac arrest does not only occur in the elderly.
01:27Or in people who lack exercise
01:29Even if you are a young and experienced runner
01:32We must not let our guard down.
01:33I wonder if anyone has noticed?
01:36Many tragedies on the marathon course
01:38The striking similarities always occur around the finish line.
01:42Experts say this is not a coincidence
01:44Because research found
01:46There are many cases of runners suffering cardiac arrest.
01:49It happened in the last quarter of the game.
01:52The expert's explanation is...
01:54When near the finish line
01:56Runners' physical abilities are usually already close to their limits.
01:59In addition to elevated body temperature, dehydration, and electrolyte imbalance
02:03At this time, some people want to sprint.
02:06To achieve better results
02:07Even if you already feel unwell
02:09I still gritted my teeth and persevered.
02:11Keep running, keep charging
02:12This leads to an abnormal spike in pulse and heart rate.
02:15Put yourself in danger
02:17What is most alarming about this tragedy is...
02:20It's definitely not just marathon enthusiasts
02:22Dr. Hao-Yun Lo, an attending cardiologist in Taiwan, reminded...
02:26Some heart diseases
02:27You may not have any symptoms at all normally.
02:29Even if you exercise regularly
02:31They might not even be able to detect it.
02:33For example, hypertrophic cardiomyopathy
02:36congenital heart disease
02:37Or problems such as abnormal electrical conduction in the heart.
02:41Both may increase the risk of serious heart rhythm disorders.
02:44Even the first attack
02:45This can lead to fainting or cardiac arrest.
02:48So even if you usually just go for a jog in the park
02:51Or go to the gym
02:52If you are trying to lose weight
02:54Suddenly challenging high-intensity exercise
02:56You should not ignore the warning signs your body gives you.
03:00That marathon is not a sport
03:02Selling sports that you can run with your legs spread open
03:04Whether you're a beginner or a seasoned runner
03:06You must understand your physical condition before participating in a competition.
03:09Especially people with serious heart disease
03:12We must not rashly attempt to challenge it.
03:14Doctors remind everyone
03:16Two major risks must be considered when engaging in this sport.
03:19First, if abnormal breathing occurs...
03:21Heart palpitations, blurred vision, dizziness
03:23Or feeling fatigued for a long time after exercise and unable to recover.
03:26It might be a cry for help from the heart.
03:28You must stop immediately and seek medical attention.
03:30Second, examine family medical history.
03:33If a family member has died suddenly from an unexplained cause
03:36Even if you are very strong and have no symptoms
03:39It is also recommended to do this before engaging in high-intensity exercise.
03:41First, have a heart checkup.
03:43After all, exercise is for health.
03:45Don't push yourself beyond your physical limits in pursuit of results.
