ally speaking, the current bracelets can recognize some simple movements, such as cycling, walking, the price gap between different bracelets, millet bracelets, Huawei bracelets and so on. 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 mincoloured wristbandsute. 2. Target Heart Rate Range of Aerobic 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. My suggestion is that if you want to get a better fitness experience, quantify the fitness data, you can buy them according to your own economic conditions. cheap-silicone-wristbands-canadabusiness-silicone-wristbands lasting, so it is very popular.

They are solid, swirled, segmented and glow. Solid color looks brief and clear. There will be only one color of the solid wristband. Different color is for different meaning. White represents making poverty history. Yellow represents living strong to fight against cancer and so on. It is awesome to wear two or more solid wristbands on one wrist of different colors which shows individuality. Swirled colors is more than one color, you can put two to four colors swirled in the wristband. The colors looks like some coatings mixed half way, some stripe and smoke of color inside. The most outstanding swirled is a camouflage wristband which usually colored of black, 463c, 574c and 459c. It is especially suitable for outdoor activities. A segmented wristband gets regular color segment from one to another, they are next to each other. We can make mostly 7 colors in a segment wristband, the tipical rainbow wristband has yellow, blue, orange, pink, purple, red and green in it. Glowing wristband will glow in dark after absorbing light come from sunshine or lamps. Why it glows ? The reason is the glowing power which is made from some special rare earth. It absorbs, store and release light energy so it does. It glows green, blue or red yet the wristband color will not be same as glowing. The wristband color of glowing can be normally white, green, blue, red, yellow, pink and purple, but it must be light enough otherwise glowing will be hard to release. The glowing usually last 3 hours and gradually weaken. But it is not the end. It recovers when absorbing light energy again. So it is recyclable. ee.
