More Accurate Workout Data
Thanks to the significant improvements made to heart rate measurement hardware and GPS hardware as well as optimizations to algorithms, the accuracy of heart rate measurements and GPS positioning for professional sports has increased greatly. For example, the accuracy of heart rate measurements has reached 5 bpm during workouts such as intermittent running and marathon events, the accuracy of route positioning has reached the track level, and the real-time pace accuracy and distance accuracy have reached industry-leading levels.
100+ Workout Modes
The watch supports GPS dual-band four-star positioning and provides multiple professional workout modes, such as Run, Cycle, Swim, Triathlon, Mountain Hike, and Trail Run. 100+ workout modes are available for your customization:
• Add your desired workout types to the list of frequently used types.
• Remove unneeded workout types from the list of frequently used types.
Professional Running Data
The watch can record a variety of professional workout data, such as time, distance, calories burnt, pace, stride, heart rate zone, aerobic training effect, anaerobic training effect, maximum oxygen uptake, and recovery time, to make exercising more scientific.
Huawei's scientific sports system provides evaluations and suggestions for entry-level runners based on the following indicators.
Multiple Heart Rate Zones
The maximum heart rate varies depending on the workout mode. Maximum heart rates can be set using different labels to accurately calculate calories burnt in a certain workout mode.
Heart Rate Zones and Pace
Five levels of workout intensity are defined using the heart rate zone and pace to represent five states of energy consumption.
After outdoor running is enabled for a period of time, the watch calculates the benefits, informs users of their current exercise status, and adjusts the strategy in a timely manner to avoid any injuries from doing exercise.
Recovery Heart Rate
The recovery heart rate refers to the difference between the heart rate at a specified time after a workout and the peak heart rate during the workout. Frequently used measurement intervals include one, two, and three minutes. The time and degree of heart rate recovery after exercise can be used to measure athletes' adaptability to training loads and their physical fitness.
Resting Heart Rate
The resting heart rate refers to the stable heart rate measured when a person is awake and relaxed. Long-term regular exercise can enhance heart functions and lower the resting heart rate.
RAI – Huawei’s Brand-New Running Capability Evaluation System
Running records are used to evaluate the running performance and quantify runners' capabilities and determine their levels.
For example, when runners go all out in a race or training session, they can be ranked or graded out of all runners from the race, which helps runners understand how well they are doing and whether they are making progress. Real-time running ability index (RAI) represents your current status, which is the level of running capability after you've finished running that day (so it will fluctuate). Recent RAI is calculated based on your recent real-time RAIs and evaluates your recent running status.
Huawei's brand-new running capability evaluation system uses an evolved algorithm. After each training session, the system calculates the RAI based on the relationship between the heart rate and pace even if runners do not push themselves to their limit. This allows users to learn about their running status in real time.
The training load is the training time multiplied by the training intensity and is an accurate reflection of the training amount and the impact of training on the body.
Maximum Oxygen Uptake (VO2Max)
Maximum oxygen uptake indicates the highest level of oxygen uptake and utilization per kilogram of body weight per time unit during a long period of intense exercise. It reflects the body's ability to intake, transport, and utilize oxygen, and is therefore an important indicator for assessing the ability to do aerobic exercise.
Aerobic training effect: This indicates the benefits of aerobic exercise for the body during a single workout. Long-term aerobic training can effectively improve the aerobic training effect.
Anaerobic training effect: This indicates the benefits of high-intensity training for the body during a single workout. High-intensity intermittent training can effectively improve the anaerobic training effect.
Smart Running Plans
The watch offers more personalized, user-friendly, scientific, and professional smart running plans. You can customize a scientific training plan based on your training goals and times. Every week, the plan is automatically adjusted based on your status and a summary is provided to encourage the completion of short-term goals. You can also customize a training plan based on your training status and feedback for the difficulty of subsequent courses to be intelligently adjusted.
Personalized training plans
Differentiated training plans are developed based on information such as runners' personal information, running goals, and running capabilities.
Intelligent adjustment of training content
With the help of the smart running plan algorithm, the watch intelligently adjusts the course schedule for the next week and pays attention to the runner's status at all times. This algorithm combines the weekly training records and user feedback, removing unnecessary choices and preventing the plans from being rigid and difficult to follow.
Based on professional theories such as "Daniels' Running Formula", the watch provides suitable guidance on running modes, exercise intensity, and exercise load. Plans can be managed through the app with ease and then pushed to the watch. The watch reminds you of your heart rate zone and pace zone in real time, providing precise guidance and preventing you from exercising incorrectly.
Real-time guidance from the watch
The training content is pushed to the watch. During this time, the watch supports switching workouts and voice and card notifications when the intensity exceeds a specified range.
Gradual capability improvement
The principle of scientific training is followed to gradually increase the training volume and improve training.
Based on Jack Daniels' classic running training system, running involves several phases, including the preliminary, improvement, consolidation, and reduction phases, which are effective at helping improve the performance of runners.
Improvement through strength training
Training plans may include suitable strength training to lay a foundation for improving performance.
Daily running plans for ordinary users
Daily scientific plans are developed for ordinary users to maintain and improve their physical fitness.
Advanced plans for runners
Advanced plans are developed for runners before a race to better control the training pace (such as reducing it before the race) on the basis of targeted improvements to performance and allow runners to stand out from the competition.
The watch identifies the current workout mode based on your workout status and reminds you to start a workout. You can ignore it or touch to enter the corresponding workout. Currently, only Indoor/Outdoor Run, Indoor/Outdoor Walk, Elliptical, and Rower support the auto-detect feature.
Workout Route Sharing
You can use the HUAWEI Health app to import other users' workout routes and share your workout routes with them.
Precise Route Back
If you get lost while on an outdoor adventure, you only need to enable the route back and real-time voice guidance features. You can then return to the original route based on the directions provided. When you get lost in environments such as deserts and hills, switch to linear navigation to quickly return to where you came from. The watch calculates the navigation distance and displays the remaining distance and estimated arrival time.
Heart Rate Broadcast
After heart rate broadcasts are enabled, the watch will continuously measure your heart rate and share your heart rate with connected devices or third-party apps.
External Heart Rate Bands
The watch can be connected to a standard heart rate band to obtain and display your heart rate data in real time during workouts, providing more choices for health and fitness enthusiasts.
External Running Form Devices
The watch can be connected a Huawei running form device to read your running data from the device while you are running. This helps you learn about your running status in a timely manner. There are nine professional running forms that are currently available: landing mode, ground contact time, ratio of ground contact time to flight time, ground contact impact, eversion amplitude, swing angle, vertical amplitude, left-right ground contact balance, and vertical stride ratio.
TruSeen 5.0+ Smart Heart Rate Monitoring
Huawei's TruSeen 5.0+ smart heart rate monitoring enables you to receive timely notifications when your heart rate is too low or too high. It supports nighttime sleep monitoring without disturbing you, and monitors your heart rate 24 hours a day to improve your health and vitality.
TruSeen 5.0+, the new-generation heart rate monitoring technology, sets up new standards for optical heart rate measurement with four major breakthroughs:
Twice as many receptor lights, with no loss of light signals
The number of photodetectors (PDs) is increased from four to eight to support multiple channels and slip prevention. Signal interference is reduced and accuracy is improved when your wrists are moving.
Upgraded AI algorithm to restore the actual light signals
The multi-channel signal enhancement algorithm and deep AI learning noise reduction algorithm are used to filter out noisy signals and restore the actual optical path to the maximum extent.
Arched design and Sapphire rear case
The ergonomic Sapphire rear case is curved and fits perfectly around the wrist. It feels comfortable and won't shake around. It picks up light effectively and improves the heart rate signal quality.
Micro-nano optical films to reduce signal interference at the superficial layer
The PD and LED use Fresnel films which effectively reduce light reflection, so that the light source directly enters the dermis, reducing signal interference at the superficial layer.
Automatic SpO2 Measurements
Oxygen saturation refers to the percentage of the combined volume of oxygen and hemoglobin to the total hemoglobin volume in the blood. Inadequate blood oxygen levels over a long time can cause damage to the brain, heart, and other organs. The watch supports automatic detection of blood oxygen levels and periodically monitors changes in your blood oxygen levels 24 hours a day. There is a dedicated card for you to view the historical blood oxygen data and learn about changes to your health.
TruSleep 2.0 constantly monitors your sleep quality while you are asleep, monitors your heart rate in real time, analyzes your breathing quality while you are asleep, and uses Big Data analytics to rate your sleep quality. With the help of Huawei's AI technology, the watch can accurately identify six types of common sleep issues and provide more than 200 suggestions for improving your sleep and personalized sleep services (such as meditation, sleep after exercising, and nap) to help you improve sleep quality.
Stress can help us stay motivated, but it also has an impact on our health. By analyzing changes to the heart rate, HUAWEI TruRelax™ is able to monitor stress in real time around the clock. Breathing exercises help you control stress and stay relaxed in day-to-day life.
Future menstrual periods and pregnancies can be intelligently predicted and understood at a glance based on previous menstrual periods.
