Heart rate refers to the number of heartbeats per minute of normal people in a quiet state, also known as quiet heart rate, which is generally 60 ~ 100 beats per minute, and may vary among individuals due to age, gender or other physiological factors. Generally speaking, the younger the age, the faster the heart rate, the slower the heart rate of the elderly than the young, and the faster the heart rate of women than men of the same age. These are normal physiological phenomena. In a quiet state, the normal heart rate of adults is 60 ~ 100 beats/min, and the ideal heart rate should be 55 ~ 70 beats/min (the heart rate of athletes is slower than that of ordinary adults, generally about 50 beats/min).

How to test the heart rate:

The simplest way to measure heart rate is to measure the pulse of "radial artery". The radial artery is located inside the wrist, close to the thumb. There is also a method for calculating the control area of exercise heart rate:

(220- current age) x0.8= maximum exercise heart rate.

(220- current age) x0.6= minimum exercise heart rate.

How to achieve better fitness effect;

In the training of swimming and other general sports, the exercise heart rate is generally controlled within the range of 120- 150 beats/min, and the morning running heart rate is generally controlled at 130- 150 beats/min. After fully mastering your effective heart rate, you can better control the amount of exercise and the amount of exercise during different exercises.
