The movement of science is as simple as this: simplify the complexity and follow one’s inclinations.

Wearable devices are flooding into our eyes under the banner of “bonus points to health”. Are these new products used by technology companies to atone for the sins of our generation that have almost destroyed the health of our generation with computers and mobile phones in the past ten years? How can we make full use of new equipment to exercise more effectively and get rid of those [computer diseases] as soon as possible scientifically? Recently, a technology company has launched a series of watches that detect the wearer’s heartbeat frequency through heart rate sensors and other components. Compared with the early wearable devices that only had the function of simply counting steps, the device can measure heart rate more accurately to help you judge the appropriate exercise intensity.

Is the heart rate measured by the wrist watch what?

Heart rate is the number of heartbeats per minute. The traditional method is to count by touching the radial artery or carotid artery pulsation at the wrist. The new device uses a series of new technologies. It saves you a series of actions of looking for arteries, looking at the clock and counting at the same time. According to the change of oxygen concentration in blood, The heart rate reference value is provided at any time. Because instead of directly measuring the pulsation of the pulse, Therefore, the results may be affected by some environmental changes. The average adult’s heart rate is usually 60-100 beats per minute, while the trained athlete’s heart rate is usually 40-60 beats per minute. The heart rate here is the resting heart rate, that is, the heart rate of a person in a quiet, awake and inactive state. Why can heart rate be measured to judge the intensity of exercise? Move, But it is different. Sometimes we have a feeling that our hearts are going to jump out after strenuous exercise. This is because when exercising, Muscles need to contract, The oxygen consumption of the whole body increases, The heart needs to speed up its beats and increase the intensity of each beat to meet this additional need. Because exercise intensity is directly related to heart rate, So we can guide the intensity of exercise by monitoring the heart rate. Usually, The ideal heart rate range matching our age and appropriate exercise intensity is called the target heart rate. Exercise in this range can not only achieve the effect of strengthening body constitution, but also prevent you from being exhausted. The target heart rate suitable for different ages is different. In general intensity exercise, the target heart rate is generally within the range of 50% ~ 69% of the maximum heart rate. For intensive exercise, the target heart rate is generally 70% ~ 90% of the maximum heart rate. According to different ages, the American Heart Association has given a general reference range: how to measure the heart rate with wearable devices? After a certain intensity of exercise, Record your heart rate. Some devices or application software can also assist in recording parameters such as maximum heart rate and average heart rate over a period of time. After exercise, by comparing the target heart rate reference range, Understand the intensity of exercise and make corresponding adjustments. 1. Adjust the intensity of exercise in time. If the heart rate is too fast and exceeds the range of the target heart rate, indicating that the intensity of exercise may be too high or the time is too long, you need to reduce the intensity accordingly to avoid sports injury; If the heart rate is too slow, then the intensity is not enough, and you need to increase the intensity. 2. Step by step adjust the target heart rate. During the first few weeks of exercise, You can set your target heart rate in a lower range (about 50% of the maximum heart rate), and then gradually increase to a higher range (about 80% of the maximum heart rate). Through regular exercise for 6 months or even longer, you can easily make your target heart rate reach about 85% of the maximum heart rate. 3. Achieve long-term goals gradually. Through long-term and systematic training, The myocardium will become thick and powerful, The shrinkage ability is improved, The volume of the heart also increases correspondingly. The blood pumped out by each heart beat is relatively increased. The heart works more efficiently. So like an athlete, The heart rate may be correspondingly low, You can readjust your target heart rate range. Special reminder: If you have cardiovascular disease, Especially when taking certain antihypertensive drugs, The heart rate may have been artificially lowered due to the action of drugs, Please be sure to consult professionals about what kind of exercise you are suitable for, what your target heart rate should be, and whether you need to adjust the intensity of exercise, so as to be safer and more effective for you. Follow your heart, follow your intuitive courage, and use modern science and technology to guide you to exercise scientifically by measuring your heart rate.
