Because of the irreplaceable value of sports, more and more people around the world are willing to participate in sports with high intensity or a large amount of exercise, such as marathon and high-intensity interval training
.
Li, Mr
.
The method of exercise is to press the heart rate near or below the peak, and gradually improve its work ability; This value is usually in the heart rate range of 130-150, and the somatosensory force is 5-6
.
As a kind of stress, exercise will temporarily increase the risk of sudden death and myocardial infarction
.
Exercise can significantly improve the level of cardiopulmonary endurance and reduce the incidence of cardiovascular diseases; 2
.
55-75 beats / min is a healthier heart rate
.
First of all, rapid heartbeat must have an impact on health
.
The negative correlation between the amount of exercise and health risk is clear and certain
.
Therefore, it is not the more exercise, the greater the health risk, but the less exercise, the greater the health risk
.
Increasing the amount of exercise should be carried out step by step, rather than suddenly increasing the amount of exercise
.
There are two main types of acute cardiac risk events caused by running: sudden death and myocardial infarction
.
If you often run (do endurance training), you will indeed have slight myocardial hypertrophy all year round, which belongs to a kind of physiological hypertrophy
.
According to the current theory, aerobic exercise will lead to the enlargement of cardiac cavity
.
Just like those elite marathon runners we know, as a result of the perennial aerobic accumulation of elite marathon runners, the same pace will be lower than the heart rate of ordinary runners; Most of the daily training is also aerobic running, so constantly monitoring your heart rate running is the correct posture for long-term and healthy running# 04 summary: running is good for heart health
.
If their heartbeat is fast and metabolism is fast, they consume more energy“ Scientifically speaking, the slower the heart rate, the healthier it is
.
Therefore, on the issue of heartbeat, too fast or too slow is not a good thing
.
Like mass runners, the amount of running is small and the training intensity is not so large
.
If you exercise step by step and make your heart stronger, the foundation laid by running can have many positive effects on your body in the 23 or 22 hours you don’t exercise in a day
.
Li, Mr
.
People’s normal heartbeat is 60-100 times / min, and the heartbeat of healthy people who exercise for a long time may be more than 50 times per minute
.
However, for people who don’t run, they are full of prejudice
.
Being responsible for running is also responsible for your health
.
Generally speaking, it is normal to cause slight myocardial hypertrophy, but the premise is to eliminate potential cardiovascular risk factors
.
Therefore, if there is heart discomfort, it should be handed over to a professional doctor for judgment# 03 for long-distance runners, the heart rate is generally slow
.
* the blue part in the figure shows the hearts of ordinary people, and the black part shows the hearts of endurance athletes
.
Exercise-induced myocardial hypertrophy is more reflected in the more developed myocardium, the enhancement of myocardial contractility and the increase of cardiac reserve, which is to meet the physiological requirements of more lasting and stable blood supply for endurance sports
.
Li, Mr
.
In other words, the overall probability of sudden death of 100000 people in various sports throughout the year is 0.31 to 2.1
.
Therefore, the heart also needs exercise
.

.
It’s not good if it’s less than 50, and it’s not good if it’s more than 80
.
” If the heart beats slowly to a certain extent and the blood supply to organs is insufficient, people will have symptoms such as dizziness and fatigue
.
Li, Mr
.
More exercise can bring more health benefits
.
There is no need for runners to stop eating because of sudden death# 02 running doesn’t hurt the heart
.
Many people who often exercise, especially long-distance runners, have a slow heartbeat
.
Sports will lead to sudden death, but sports is not the main inducement of sudden death
.
Heart rate is an important data of human vital signs
.
There are still some media who do not understand the situation attributed the reason to running, and even called it a flood and beast
.
For a long time, numerous epidemiological and Bioscience studies have proved such important viewpoints: 1
.
Therefore, running itself won’t hurt the heart, people’s body, and people’s lives
.
Li, Mr
.
Carefully divide it
.
The process of exercising the heart is very similar to that of exercising muscles
.
This risk is most likely to occur in people who are not used to exercise, and the probability of such risk events in people who exercise regularly is lower than the former; If measured by absolute risk value, the probability of sudden death during exercise per 100000 people a year is 0.31-2.1
.
After the incident, emergency personnel rushed to the scene
.
Li, Mr
.
Running itself will not hurt the heart, damage people’s body, nor threaten people’s lives
.
Seeing these words, I believe most runners will scoff, but it will also shake some people’s confidence in running and even dare not run again
.
Li, “regular high-intensity exercise will make the heart bigger and more prone to heart disease.” On August 16, a 42 year old man suddenly collapsed while running in Yutan Park in Ningxiang, Hunan Province
.
It is well known that running is beneficial to physical and mental health and has many benefits to the body, so it also attracts more and more people to run
.
Many tragedies happen more because of rashness, irresponsibility for running and irresponsibility for life
.
Sudden death or heart accidents that occur occasionally during marathon or daily running warn runners to exercise scientifically and appropriately, but for the vast majority of the public, the benefits of long-term and systematic exercise training still significantly outweigh its risks
.
Normal people live a lifetime, the heart beats 2.5-3 billion times, so the slower the heart beats, the longer the life
.
This tragedy is indeed sad and regrettable, and once again sounded an alarm to the majority of runners, but we also saw some disharmonious contents
.
However, at present, this conclusion is only based on epidemiological investigation and animal experiments, and can not really Group real people for control experiments, so it has limitations
.
Remember, no matter where you train and play, home is the only destination
.
On the contrary, it is good for heart health
.
The more we run, the stronger the intensity, the stronger and bigger the heart will be, so as to better deliver blood to the muscles being exercised
.
of Peking University and cardiovascular expert, also gave an answer
.
Then, is it good for the heart to insist on running# The risk of running is much lower than that of people who do not exercise
.
The study found that the average life span of athletes is 3-6 years longer than that of ordinary people
.
This heart rate must be within a certain range
.
Secondly, the myocardium will be slightly thickened, which has been recognized by the medical community
.
People who live long usually don’t have a fast heartbeat
.
Heart contraction consumes energy
.
The prospective cohort study on the impact of long-term exercise training on heart health shows that there is no upper limit on the amount of exercise to improve cardiopulmonary function and reduce all-cause mortality
However, if the heart rate is too slow, only thirty or forty times per minute, it belongs to bradycardia in arrhythmia, which can lead to fatal diseases as well as tachycardia
.
Li, Mr
.
For this problem, Zhong Youmin, M.D
.
Every time they see the news of sudden death due to running, they will say these alarmist words to runners: “don’t run! The news says someone died suddenly again! Mr
.
Li, Mr
.
The most important change of aerobic exercise to the heart is not myocardial hypertrophy, but the expansion of cardiac cavity
.
Li, Mr
.
The probability of sudden death in sports is also very low, far lower than that of the general population
.
But after half an hour of rescue, he still failed to save the man’s life
