Why the detected light of heart rate monitoring is commonly green?

As for a red liquid like blood, the absorption rate of green light is the largest, so the observing data would be more accurate.

When the user’s heart beats, more blood will flow through the wrist, and the green light will increase absorbing more signals. While, in the heartbeat gap, blood flow reduced, resulting in a decrease in green light absorption.

After you realize your maximum heart rate, how does smart bracelet work in exercising?  We all know that the exercise is divided into aerobic exercise and anaerobic exercise, and the heart rate value which is gradually increased from aerobic exercise to anaerobic exercise is called maximum aerobic heart rate (MAF)

MAF is a training method that has been implied for 20 years. It will allow you to burn fat at a reasonable pace. This kind of full training will allow you to collect valuable carbohydrates in long distance races, thus avoiding “wall crashes” during marathons and longer distance races; Besides, it can greatly strengthen your thighs and hips, and Unconsciously, you have another “motor” in your body.

To find your maximum aerobic training heart rate, there are two important steps.

·Subtract your age from 180.

·Modify this number by selecting among the following categories the one that best matches your fitness and health profile:

a)  If you have or are recovering from a major illness (heart disease, any operation or hospital stay, etc.) or are on any regular medication, subtract an additional 10.

b)  If you are injured, have regressed in training or competition, get more than two colds or bouts of flu per year, have allergies or asthma, or if you have been inconsistent or are just getting back into training, subtract an additional 5.

c)  If you have been training consistently (at least four times weekly) for up to two years without any of the problems in (a) and (b), keep the number (180–age) the same.

d)  If you have been training for more than two years without any of the problems in (a) and (b), and have made progress in competition without injury, add 5.

For example, if you are 30 years old and fit into category (b), you get the following: 180–30=150. Then 150–5=145 beats per minute (bpm).

In this example, 145 must be the highest heart rate for all training. This allows you to most efficiently build an aerobic base. Training above this heart rate rapidly incorporates anaerobic function, exemplified by a shift to burning more sugar and less fat for fuel.

By the way, today’s smart bracelet also has blood pressure monitor function.

It’s a new blood pressure measurement method, even you don’t carry a mobile phone, you can also click on the bracelet to open the blood pressure measuring interface and monitor your blood pressure in 30s.

All in all, If you’re an exerciser, the smart bracelet can be a great tool, serving as a steward of your body’s key data to help you exercise in a scientific way.
