SUUNTO CHRISTMAS GIFT GUIDE | 45-DAY FREE RETURNS
Good aerobic fitness is important for your overall health, well-being and sports performance.
Your aerobic fitness level is defined as VO₂max (maximal oxygen consumption), a widely recognized measure of aerobic endurance capacity. In other words, VO₂max shows how well your body can use oxygen. The higher your VO₂max, the better you can use oxygen.
The estimation of your fitness level is based on detecting your heart rate response during each recorded running or walking workout. To get your fitness level estimated, record a run or walk with a duration for at least 15 minutes while wearing your Suunto 9 Peak Pro.
Your watch is able to provide an estimation of your fitness level for all running and walking workouts.
Your current estimated fitness level is shown in the fitness level widget. Swipe left from the watch face or press the middle button to scroll to the fitness level widget.
If the watch has not estimated your fitness level yet, the fitness level widget will instruct you further.
Historical data, from recorded running and walking workouts, plays a role in ensuring the accuracy of your VO₂max estimate. The more activities you record with your Suunto 9 Peak Pro, the more accurate your VO₂max estimate becomes.
There are eight fitness levels, from low to high: Very poor, Poor, Fair, Average, Good, Very good, Excellent and Superior. The value is dependent of your age and gender and the higher value you have, the better your fitness level is.
The widget also views your estimated fitness age. Fitness age is a metric value that reinterprets your VO₂max value in terms of age. Regularly engaging in the right types of physical activity will help you boost your VO₂max value and reduce your fitness age.
Improvement of VO₂max is highly individual and it depends on factors such as age, gender, genetics and training background. If you are already very fit, increasing your fitness level will be slower. If you are just starting to exercise regularly, you may see a quick increase in fitness.
