A 25-year-old guy's heart rate is only 52

We all know that for some young people, because they are in their best time, their bodies will be particularly strong and their hearts will beat powerfully, especially some young men in their twenties and thirties. Their normal heartbeat should be seventy or eighty beats per minute. However, some people have physical illnesses, so their heart rate may be around 50. So what should a 25-year-old boy do if his heart rate is only 52?

An adult's heart beats about 70 to 80 times per minute, but 60 to 100 beats per minute is normal. The heart beats faster when working than when resting, women beat faster than men, children beat faster than adults, and newborns can beat up to 150 times per minute. On average, if a person lives to be 100 years old, his or her heart beats a total of about 4 billion times. Normally, if an adult's heart beats more than 100 times per minute at rest, it is medically considered "tachycardia"; if it is less than 60 times per minute, it is considered "bradycardia". Some people's heartbeats may speed up, slow down, or stop and start. These all fall within the range of abnormal heartbeat. Abnormal heartbeat is one of the symptoms of heart disease.

However, like many organs in the body, the heart's working capacity can vary and it has a lot of room for flexibility. According to research, if you do a set of radio gymnastics carefully, your heart rate may increase by 20 to 30 beats per minute. When people are angry or afraid, students' hearts will beat faster when they are about to enter the examination room. Athletes climbing Mount Everest have a heart rate of 170 to 180 beats per minute. If some people are asked to run 300 meters with a 30 kg weight, their heart rate will exceed 200 beats per minute. Medical records show that the heart rate was as high as 270 beats per minute.

The purpose of speeding up the heartbeat is to pump more blood to meet the body's needs for labor, exercise and special circumstances. If the heartbeat is too slow and the blood supply is insufficient, the body will not get the necessary oxygen and nutrients and people will not be able to live a normal life, and even more serious consequences may occur. Physiologists have found that people who engage in heavy physical labor and intense exercise for a long time have their hearts exercised and their heart rate is much less than that of normal people.

There is a football player in our country today whose heart beats only 37 times per minute; in the 1928 Olympics, there was an athlete whose heart beat only 28 times per minute. It turns out that people whose hearts get better exercise have larger myocardial fibers, thicker ventricular walls, and larger hearts themselves. After a former British world marathon champion died of cancer at the age of 70, doctors found that his heart was about 30% heavier than a normal person's, and the blood vessels supplying it, the coronary arteries, were about 1 times thicker. Such a heart naturally contracts very strongly and powerfully, and the amount of blood delivered to the whole body with each beat is many times more than that of an ordinary person. Therefore, although the heart beats less, the body's normal needs can be met due to the abundance of blood.
