The best time to measure the static heart rate is in the morning, when we naturally wake up and still lie in bed without any physical activity. Before measuring, we take a deep breath to completely relax our bodies.
The best measuring positions are brachial artery and radial artery. When measuring, we press the brachial artery and radial artery with the index finger and middle finger. Three times a minute, with no interval? And then calculate the average, which is your current static heart rate level.
The average person's normal heart rate is 72 beats per minute for men and 80 beats per minute for women. If friends who often participate in sports will find that the heart rate will be very low, don't be afraid, which means that your heart and lung level is very good. Athletes' static heart rate is mostly 50-60 beats/min. If friends who often participate in sports, their static heart rate should be 60-70 beats/min.
Pay attention to ensure good health when measuring heart rate. For example, drinking the day before the measurement, too tired will have an impact on the measurement results. We can choose a few more mornings for the test, and the closer value is the correct heart rate level.
Extended data:
Increased heart rate is harmful to health, shortens life expectancy and increases the incidence and mortality of cardiovascular diseases. How to keep the resting heart rate at about 60 beats/min;
1. Movement
Regular participation in various exercises with appropriate intensity will slow down the resting heart rate. Although the heart rate increases during exercise, exercise can exercise the heart function, thus slowing down the resting heart rate.
The general suitable exercise heart rate is "170- age". For a 50-year-old person, it is appropriate to control the exercise heart rate at 120 beats/min. Too fast means too much exercise to achieve or have no effect. Before exercise, you should feel comfortable and not tired. General exercise should not exceed 1 hour, and 30 minutes to 60 minutes at a time is the best. Exercise at least three times a week.
2. Correct bad lifestyle
Staying up late, smoking and drinking will accelerate the resting heart rate. Drink less strong tea, especially before going to bed, otherwise it will easily lead to insomnia. You should also defecate regularly to keep defecation unobstructed.
Maintain a proper weight
Obesity will increase the burden on the heart and speed up the heart rate. Therefore, obese people should maintain proper weight through physical exercise and diet adjustment.
Keep peace of mind
Be calm in life, don't always be anxious and angry. If the heart rate is too high because of tension and anger, you can gradually restore calm by listening to music and meditation.
5. Drug therapy
Some diseases, such as hypertension and coronary heart disease, can lead to an increase in heart rate. Can take medicine according to the doctor's advice, slow down the heart rate, protect the heart, reduce and control myocardial ischemia events, improve heart function and prolong life.
There are two common measuring principles of heart rate meter, one is cardiac current measurement and the other is photoelectric transmission measurement.
Cardiac current measurement
Every heartbeat of our human body will produce cardiac current, and the wireless heart rate chest strap is such an instrument that can sense cardiac current. The pole pieces of the sensor are located on both sides in front of the chest strap. After the user wears the chest strap, the pole pieces in the chest strap collect the fluctuation amplitude of the exerciser's heart current, and then send it to the heart rate meter through wireless transmission technology, which is converted into the heart rate BPM value for easy observation.
Its principle is consistent with that of ECG measurement. Another advantage of this method of measuring heart rate is that it can continuously measure heart rate during exercise.
According to the types of sensing electrodes, wireless heart rate chest strap can be divided into traditional hard heart rate chest strap and new flexible fabric soft chest strap.
The hard heart rate chest strap is made of conductive rubber electrode blocks embedded in the hard plastic strap.
Flexible fabric soft heart rate chest belt adopts flexible film electrode and is welded on the flexible fabric belt by hot pressing. It is very light and comfortable to wear, which reduces the friction interference caused by the movement of the chest belt during exercise.
Photoelectric transmission measurement method
Photoelectric measurement is to measure pulse by using the change of hemoglobin absorbance in blood vessels. The watch is equipped with an infrared emitting beam loop and a receiving and reflecting loop. The advantage of this method is that it is very simple to measure the heart rate without a chest strap, but because the signal is very weak and easily disturbed by the outside world, the measurement data is inaccurate, so it is generally necessary to measure the heart rate in a quiet state, which is not suitable for continuous measurement of the heart rate during exercise.
The green photoelectric measurement method consists of two light-emitting diodes with green wavelength and a photosensitive sensor, which is located on the back of the heart rate meter. The principle is based on the fact that the blood in the blood vessels of the arm will change its density when it pulsates, thus causing the change of light transmittance. The LED emits light waves with green wavelength, and the photosensitive sensor can receive the light reflected by the arm skin and sense the change of light field strength and convert it into heart rate.
