After the workout, the workout records will be synced and saved to the Zepp App, and displayed in [Workout] - [Workout Records].

The device provides a wealth of sports physiological indicators, and the scores evaluated can provide corresponding references for your sports. These indicators can be viewed in the sports record or sports status application, including the current training load, full recovery time, maximum oxygen uptake data, training effect, etc.

For detailed explanations of training load, full recovery time, and VO2 max, refer to the "Exercise Status" app.

The exercise effect (abbreviated as TE) is an indicator used to measure the effect of exercise on improving aerobic exercise ability. When wearing the device for exercise, the TE score will increase from 0.0 and accumulate as you exercise. The score range is 0.0-5, and different score ranges represent different effects. The higher the score, the greater the intensity of exercise and the greater the pressure on the body, but it also indicates that the effect of this exercise may be better. Of course, when TE reaches 5.0, attention should be paid to whether the body load is too high.

Aerobic TE Score	Effect on enhancing aerobic capacity
0.0-0.9	This exercise has no effect on aerobic capacity enhancement
1.0-1.9	This exercise helps to improve endurance and is also suitable as a recovery exercise after a workout
2.0-2.9	This exercise is helpful for maintaining aerobic capacity
3.0-3.9	This exercise significantly helps enhance aerobic capacity
4.0-4.9	This exercise has a significant effect on the enhancement of cardiopulmonary capacity and aerobic capacity.
5.0	Non - professional players should do a good job in post - exercise recovery.

Anaerobic TE Score	Effect on improving anaerobic exercise capacity
0.0-0.9	This exercise has no effect on the anaerobic capacity enhancement
1.0-1.9	This exercise has a minor effect on improving anaerobic exercise capacity
2.0-2.9	This exercise is helpful for maintaining anaerobic exercise capacity
3.0-3.9	This exercise is helpful for improving anaerobic capacity
4.0-4.9	This exercise has a significant effect on the enhancement of anaerobic exercise capacity
5.0	Non - professional players should recover after exercise

The TE score is evaluated based on your personal information, heart rate and speed during exercise. A low TE score does not mean there is something wrong with your exercise, but only indicates that the exercise is relatively easy and has no significant effect on enhancing aerobic capacity (for example, if you jog for an hour, the TE score will still be very low).

How to obtain it?

For all sports that can monitor heart rate data, the TE score will be presented after the end of the exercise, and relevant evaluations or suggestions will be provided. You can also view it again in each exercise record later.

The data in the exercise state includes exercise load, full recovery time and maximum oxygen uptake. The device will calculate these indicators based on your personal information and the data generated during exercise. As the device is used and data accumulates, we will have a better understanding of your body and exercise data, and the evaluation of these indicators will become more and more accurate.

Maximal oxygen uptake refers to the amount of oxygen that the human body can take in during maximum intensity exercise. It is an important indicator of the body's aerobic exercise capacity. As one of the important reference data for endurance athletes, a high level of maximal oxygen uptake is the basis for a high level of aerobic exercise capacity.

The maximum oxygen uptake is relatively personalized, and there will be different reference standards for different genders and age groups. The device will evaluate your exercise ability based on your personal information, heart rate and speed generated during exercise, and will change as your exercise ability changes. Of course, everyone has their own upper limit of maximum oxygen uptake, which is determined by the individual body.

The VO2 max score corresponds to seven different levels of fitness: novice, beginner, fair, moderate, good, excellent, and superior.

How to get it:

1. Enter accurate personal information in the app;
2. Wear the device and run outdoors or cross-country for at least 10 minutes, and generate a heart rate value that reaches 75% of your maximum heart rate.

How to view:

You can view your current VO₂ max in the Zepp App's sports status, as well as your historical VO₂ max and trends.

The exercise load is calculated based on your EPOC (excess post-exercise oxygen consumption). The longer and more intense the exercise, the higher the value. We have counted the total exercise load in the past 7 days to show the burden on your body caused by your recent exercise.

There are three intervals for exercise load, namely: low, moderate and high.

If the value is low, it will not help much to improve the exercise ability; if the value is high or too high, the body will be more tired, which is not only not conducive to effectively improving the exercise ability, but may also cause more exercise risks. If you want to continuously improve your exercise ability within the scope of your body's tolerance, it is recommended to keep the exercise load in a moderate range.

The moderate range is calculated based on your recent and long - term exercise data, and will become more and more accurate as you use it.

How to get it:

Start the exercise mode on the device to exercise. When the exercise volume reaches the minimum unit of the minimum exercise load, the exercise load of the current exercise can be obtained. The accumulated exercise load in the past 7 days can be viewed in the exercise status of the APP.

How to view:

You can view the current exercise load in the exercise status of the Zepp App, and you can also view the historical exercise load and its changing trend.

The full recovery time is the recommended time for the body to fully recover. After each exercise, recovery suggestions will be given based on the latest exercise heart rate to help you recover better and arrange your exercise reasonably to avoid sports injuries.

Full recovery time	Exercise advice
0 - 18 hours	You have completed or nearly fully recovered and can perform slightly higher intensity improvement training
19-35 hours	You can train as usual and prepare to strengthen your physical fitness again
36-53 hours	Appropriately reducing the training intensity allows you to reap the benefits of the previous workout. You can do some recovery exercises to relieve physical fatigue.
54 - 96 hours	Taking appropriate rest allows you to reap the benefits of your previous high-intensity workout

What is body electricity?

Body Battery measures the change in your body's energy throughout the day. It calculates a score based on data such as night-time sleep, daytime rest, heart rate variability, resting heart rate and activity levels. Daily activities, exercise and stress can all deplete your Body Battery, while sleep and relaxation help to recharge it. For a more accurate assessment of your Body Battery, we recommend wearing your device throughout the day. If you have multiple devices paired, the data from all devices will be combined to calculate your Body Battery score.

What is the morning charge?

Morning body battery is the body battery score you have when you wake up in the morning. It reflects your physical and mental readiness for the new day. It is calculated based on your night's sleep, heart rate variability, resting heart rate and activity data from the last three days. Usually after a night's sleep, your body battery score is highest when you wake up in the morning. A high morning body battery score means you may be ready for a strenuous workout or better focus at work. A low morning body battery score may mean your body needs rest and recovery.

Why is the body battery score inaccurate in the first few days?

During the first 7 days of wearing the device, we will establish a base line model for your various indicators. The evaluation during this period is estimated based on the average data of most users, so it may not fully reflect your actual situation. But when you continue to wear it for 7 days, the system will create a base line model specifically for you.

When you wear the device to sleep, it will automatically record your sleep information. The device can record both night sleep and naps. The device will identify sleep based on your sleep plan. Sleep that overlaps with the planned period of the day will be recorded as the main sleep of the day. If no plan is set, 0:00-8:00 will be used as the default identification period. Sleep that is more than 60 minutes apart from the main sleep will be recorded as a nap. Sleep less than 20 minutes will not be recorded.

Assist Sleep Monitoring

Click [Health Monitoring] on the device management page in the Zepp App to enter the health settings page, where you can turn on the auxiliary sleep monitoring. When the device detects that you fall asleep, it will automatically record more sleep information, such as the REM sleep stage.

Sleep Apnea Monitoring

Click [Health Monitoring] on the device management page in the Zepp App to enter the health settings page, where you can turn on the sleep breathing quality monitoring. When the device detects that you fall asleep, it will automatically monitor your breathing quality to help you better understand your sleep status.

Heart rate is an important indicator of physical condition. Higher frequency heart rate measurements help capture more heart rate changes and provide reference for a healthy lifestyle. To ensure the accuracy of the measurement, please wear the device correctly according to the wearing instructions, keep the wearing part of the device clean, and avoid applying sunscreen.

After the device is paired, the device automatically and continuously measures the heart rate throughout the day. You can view information such as the heart rate curve, resting heart rate, heart rate variability, and heart rate zone distribution in the Zepp App.

4. The measuring range of this product is 78%-100%. This function is for reference only and should not be used as a basis for medical diagnosis. Please consult a medical institution if you feel unwell.

Stress is calculated by the change of heart rate variability value, which is an indicator to evaluate the change of physical state. Usually when the stress is high, you should take appropriate rest.

Automatic Pressure Monitor

After turning on the automatic stress monitor switch in the [Health Monitor] of the Zepp App, the device will automatically measure stress every 5 minutes and record the stress changes throughout the day.

Relax reminder

The device will alert you if the stress remains above the limit for 10 minutes in a quiet state (except during sleep).

1. After the automatic pressure monitoring is turned on, the stress relief reminder function can be enabled;
2. In the stress settings, turn on the pressure relief notification to receive reminders.

PAI Vitality Index is a personal physiological activity indicator. Based on heart rate data, combined with multi-dimensional dynamic comprehensive evaluation of daily activity intensity and personal physiological data, it is converted into an intuitive PAI value through an algorithm. It does not rely on single item data, allowing you to comprehensively understand your physical condition.

You can earn PAI points through daily activities or exercise of a certain intensity. According to the results of the HUNT Fitness Study *, maintaining a PAI score of 100 or higher is associated with a lower risk of cardiovascular disease and a longer life expectancy. For more information, please visit Zepp App > PAI > PAI Q&A.

*HUNT Fitness Study: This study is a sub-project of the HUNT study, led by Professor Ulrik Wisloff of the School of Medicine at the Norwegian University of Science and Technology. The HUNT study has been ongoing for more than 35 years and involves more than 230,000 participants.
