Explanation of heart rate concepts

Heart rate

Heart rate is the number of heartbeats per minute. The watch supports 2 types of heart rate monitoring: “continuous heart rate monitoring” and “single heart rate measurement”.

After continuous heart rate monitoring is turned on, the heart rate sensor will be turned on 24 hours a day to continuously monitor heart rate changes. Continuous heart rate monitoring mode may increase watch power consumption.

Resting heart rate

Resting heart rate refers to the heart rate when a person is awake and inactive. It can be understood as the minimum amount of pulse the heart requires to maintain the body’s basic metabolism. The stronger the heart’s ability, the fewer heartbeats under the same basic metabolic consumption, that is, the lower the resting heart rate.

Resting heart rate is one of the health indicators that reflects the capabilities of a person’s cardiovascular system. The resting heart rate of adults is usually in the range of 50-100 beats/min, while the resting heart rate of professional athletes is usually in the range of 40-60 beats/min. Maintaining regular, moderate-intensity exercise can lower your resting heart rate.

However, resting heart rate may be affected by people’s health and amount exercise. For example, resting heart rate will usually increase when you’re sick; if you do a high-intensity workout one day, your resting heart rate will usually increase the next day.

Continuous tracking of resting heart rate can better reflect changes in human cardiovascular capacity. The watch keeps track of changes in resting heart rate through continuous heart rate monitoring, and presents users with a resting heart rate curve for the last 30 days, allowing them to understand their health through trends in their resting heart rate.

Maximum heart rate

The maximum heart rate refers to a person’s maximum number of heartbeats per minute. The maximum heart rate usually occurs during continuous vigorous exercise. As people age, their maximum heart rate usually decreases.

The watch infers the user’s maximum heart rate based on gender and age information entered by the user, while updating the maximum heart rate based on the actual measured heart rate while the user is wearing the watch.

The maximum heart rate is usually used as a reference for measuring exercise effects or heart rate zone. It is impossible to evaluate exercise effects and energy expenditure at different heart rate levels without the maximum heart rate.

During a workout, the closer it gets to the maximum heart rate, the heavier the load for the heart. If the heart does not bear a certain intensity of load during exercise, it can’t reach the goal of strengthening the heart’s ability to exercise or enhancing aerobic exercise ability; however, if the heart is under a high-intensity load for a long time, it may lead to heart dysfunction, sudden death, injury and other risks due to excessive exercise. Therefore, the maximum heart rate is an indispensable basic reference index in workout evaluation.

Heart rate zone

The heart rate zone refers to the range or level of the user’s current heart rate compared to the maximum heart rate. The heart rate zone reflects the load level of the heart and is usually used to measure a person’s exercise intensity.

The watch uses the maximum heart rate as a reference and divides the heart rate into 5 zones: Extreme, Anaerobic, Aerobic, Fat burning and Warm-up.

In the daily heart rate log, as well as in the heart rate portion of exercise reports, the watch will display the cumulative time proportion of each heart rate zone.
