What is the relationship between pulse rate per minute and health?

An adult's heartbeat is about seventy or eighty beats per minute, but it is normal between 60- 100. Jump faster at work than at rest, women jump faster than men, children jump faster than adults, and newborns can jump 150 times per minute. An average person lives 100 years old, so the total number of heartbeats can reach about 4 billion.

In normal times, if the adult's heartbeat exceeds 100 times per minute when he is quiet, it is medically considered as "tachycardia"; Less than 60 times is "bradycardia". Some people's heart beats fast and slow, jumping and stopping These are all within the range of abnormal heartbeat. Abnormal heartbeat is one of the symptoms of heart disease.

However, like many organs of the body, the working ability of the heart can be changed, and it has a lot of room for expansion and contraction.

According to research, if you finish a set of broadcast gymnastics seriously, your heart rate may increase by twenty or thirty times per minute. When people are angry and afraid, when students are in the examination room, their heart beats faster. The heart rate of athletes climbing Mount Everest is 170 to 80 beats per minute. Let some people run 300 meters with a load of 30 kilograms, and their hearts beat more than 200 times per minute. Medical data recorded a heartbeat as high as 270 times.

The purpose of quickening the heartbeat is to send more blood to meet the needs of manual labor, sports and special circumstances. If the heartbeat is too small, the blood supply is insufficient, and the body can't get the necessary oxygen and nutrition, people can't live normally, and even lead to more serious consequences.

Physiologists have found that people who have been engaged in heavy physical labor and high-intensity exercise for a long time have exercised their hearts and their heartbeat times are much less than ordinary people. There is a football player in our country today. His heartbeat is only 37 times per minute. 1928 At the Olympic Games, an athlete only played 28 times a minute. The results show that people who get better heart exercise have thicker 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 that of normal people, and the feeding artery-coronary artery was about 1 times. This kind of heart naturally contracts badly, and every time it beats, it sends twice as much blood to the whole body as ordinary people. So although I jump less, I can meet the normal needs of my body because of my blood.
