In May 2019, a 40 year old man ran in Shenzhen stadium and fell to the ground due to sudden cardiac arrest

.

Stadium security found that someone fell, quickly brought AED, on-site staff for him to take turns for cardiac resuscitation and artificial respiration, people also quickly dial 120

.

The man has been rescued

.

There is a runner on his marathon assistant

.

He has been running for many years since 2005

.

At the beginning of this year, he found that he had heart discomfort

.

In February, he went to the hospital for examination and found that his left atrium and right atrium were a little out of limits, with mild aortic regurgitation

.

Tu / marathon assistant he said that after running for so many years, his heart rate is almost above 160, and his color Doppler ultrasound shows that both sides are too large, with mild aortic insufficiency

.

Photo / marathon assistant runs for ten years, but his heart is broken! Is exercise healthy or destructive? 01 ran 8 kilometers, suddenly fainted in front of a dark Hangzhou Mr

.

Jin (alias), 50 years old, he is 40 years old from the start of the marathon

.

At that time, when he was middle-aged, he gradually became fat and weighed more than ten jin in a few months, so he decided to run to lose weight

.

Running is addictive

.

Mr

.

Jin keeps the habit of running 10 kilometers along Qiantang River the next day

.

In the past 10 years, he has become a marathon enthusiast and participated in many marathons

.

He has run 42 kilometers and the best result is 3 hours and 20 minutes

.

Slowly, running on the flat ground can no longer satisfy him

.

He chose to challenge the mountain marathon and enjoy the beautiful scenery while running

.

One year in Taizhou, I ran for 16 hours before dawn

.

One day in April last year, after running 8 kilometers, he suddenly fell into darkness and fainted! Fortunately, I’ll be up soon

.

Mr

.

king is scared

.

What’s the matter? After a few days, he made a second attempt

.

This time, he specially wore a professional heart rate band and tied it to his chest to measure his heart rate

.

After nearly half of the run, Mr

.

Jin felt black again

.

He felt dizzy like he fainted last time

.

He quickly stopped, when a look at the heart rate, it was more than 170

.

Although both times he fainted, he just sat down or lay down for a rest, but Mr

.

King realized that something should be wrong with his body

.

When he went to the hospital for examination, he was diagnosed with atrial fibrillation

.

According to the doctor’s analysis, it was related to Mr

.

Jin’s long-term running and cardiac overload

.

The doctor suggested that he do some gentle exercise

.

Now, Mr

.

Jin has been afraid to run

.

His daily routine is walking, and he doesn’t even dare to play

.

After retirement, many athletes have heart enlargement exercise, which can enhance the body’s blood supply ability

.

When the heart beats once, more blood will be pumped out, and the number of heart beats will be less

.

Originally, 70 or 80 beats per minute can fully supply blood

.

After exercise, maybe 60 beats is enough

.

But the slow heartbeat of athletes is not necessarily a good thing

.

The kind of sports of athletes is different from the general sports that we advocate

.

Competitive sports require that the body function be brought into full play to compete

.

The amount of exercise exceeds the load of the human body, which will have an impact on important organs

.

Long term strenuous exercise, the body compensation to a certain extent, lost compensation, irreparable damage

.

“Athletes’ muscles are thicker than ordinary people, so is their heart

.

If they continue to exercise at high intensity, their ventricular walls will thicken and their heart will expand over time.” The heart rate of athletes is generally 40 or 50 times per minute

.

Long time overload training will have the risk of heart enlargement, which is quite common among retired athletes

.

Myocardial hypertrophy is the most common heart problem of athletes

.

Long term, intense exercise, myocardial cells continue to contract, myocardial cells will be hypertrophy, hypertrophy to a certain extent, myocardial cells will apoptosis

.

For athletes, the most direct injuries of high-intensity sports are muscle strain, fracture, etc., while heart disease is slowly buried day after day

.

0355 ~ 75 beats / min is a relatively healthy heartbeat

.

First of all, too fast heartbeat certainly has an impact on health

.

However, at present, this conclusion is only based on epidemiological investigation and animal experiments, and can not be divided into human groups for control experiments, so it has limitations

.

The normal heart rate of people is 60-100 beats / min, and the heart rate of healthy people with long-term exercise may be more than 50 beats per minute

.

But if the heart rate is too slow, only 30 or 40 times per minute, it belongs to bradycardia in arrhythmia, which can also cause fatal diseases

.

So when it comes to heartbeat, too much is not enough, too fast or too slow is not a good thing

.

Long life people’s heart rate is not too fast, heart contraction is the consumption of energy, heart rate is fast, metabolism is fast, consume more energy

.

“Scientifically speaking, the slower the heart rate, the healthier it is

.

The heart rate must be within a certain range

.

If you divide it carefully, 55-75 beats per minute is a relatively healthy heart rate

.

If it’s less than 50 beats, it’s not good

.

If it’s more than 80 beats, it’s not good.” Slow heartbeat to a certain extent, organ blood supply is not enough, people will appear dizziness, fatigue and other symptoms

.

Therefore, the heart also needs exercise

.

The method of exercise is to keep the heart rate near or below the peak value, and gradually improve its work ability

.

This value is usually in the heart rate range of 130-150, and the body feeling is 5-60%

.

As we know, elite marathon runners, as a result of their aerobic accumulation all year round, also have lower heart rate than ordinary runners

.

Most of their daily training is also aerobic running

.

Therefore, it’s the right posture to constantly monitor their heart rate running! Not enough? Star top, the first time to receive push! Part of the content and pictures of end are from happy running, marathon assistant and internet infringement
