tion of motion detection and sleep monitoring, but the detection accuracy of different hand rings is also different.

For a friend who loves fitness, we know that heart rate is an important parameter. The heart rate calculation of aerobic exercise is studied by experts and scholars. By comparing the heart rate after aerobic exercise (temporarily called actual heart rate) with the target heart rate, when the actual heart rate is within the range of the target heart rate, aerobic exercise can be considered effective and normal; when the actual heart rate is lower or higher than the target heart rate, aerobic exercise is ineffective, and the exerciser is slightly less effective. Micro-control the amount of exercise, so as not to let aerobic exercise into "aerobic exercise". The relationship between specific aerobic exercise and heart rate has the following empirical formulas: 1. The actual heart rate of aerobic exercise: the maximum of heart rate per minute. 2. Target Heart Rate Range of carabiner keychainAerobic Exercise Primary Formula: For people in poor health. Target heart rate = (200-age)* (60%-80%) 60%~70% is mainly used to reduce fat, 70%~80% is mainly used to improve cardiopulmonary function. General formula: for the general population. Target heart rate = (220-age)* (60%-80%) 60%~70% is mainly used to reduce fat, 70%~80% is mainly used to improve cardiopulmonary function. Caffonen formula: for people with higher physical fitness. Target Heart Rate=(220-Age-Resting Heart Rate)*(65%-85%)+Resting Heart Rate 65%~75% is mainly used to reduce fat, 75%~85% is mainly used to improve cardiopulmonary function. According to the above formula, everyone can be seated. If the bracelet has heart rate detection function, the actual heart rate during exercise can be measured in real time, so that you can judge whether your aerobic exercise is effective. There are not a few bracelets on the market for heart rate detection, and the accuracy of each bracelet has not been fully evaluated.
