`“ What is VO2 Max?
`
`VO? Max Is a measurement of how well your body uses oxygen when you're
`working out at your hardest.It is widely accepted as the gold standard for
`grading cardiovascular fitness: the higher your VO2 Max, the morefit you are

`based activities Including running, biking, and swimming (source).

`VO2 MaxIs traditionally measured in a lab where you run on a treadmill orri
`stationary bike until exhaustion with a mask strapped to your nose and mouth to
`gauge the amountofalr you Inhale and exhale. While this method provides the
`most accurate measure of VO2 Max, your Fitbit device can estimate this value for
`you with less effort and discomfort.
`
`Fitbit estimates your VO2 Max and refers to It as your cardio fitness score.
`
`“ How doesFitbit measure my cardio fitness score?
`
`Your cardlo fitness score is determined by your resting heart rate, age, gender,
`weight, and other personal information. For best results, make sure your weightIs
`correct In your Fitbit profile. Also, wear your tracker or watch to sleep for a better
`resting heart rate estimate. Your cardlo fitness score will be shown as a range
`unless you use GPSfor runs.
`
`“ How dolget a more precise estimate of my score?
`
`lf your Fitbit device connects to GPS, we can provide a more precise estimate of
`your score using therelationship between pace and heart rate during your runs.
`This Is because Individuals with higher VO2 Max have a lower heart rate while
`running at the same pace comparedto individuals with lower VO2 Max.If you're
`able to run at a comfortable pacefor at least 10 minutes, track a run with GPS. We
`recommend running on flat terrain as muchas possible since only the flat
`sections of your run count toward your score estimate. You may need to go on
`several runs that are at least 10 minutes In length to affect your score,
`
`For instructions on how to start In the Exercise app, see How do!track my
`workouts with my Fitbit device?
`
`“A How doesFitbit calculate my cardio fitness level?
`
`We use your cardio fitness score In combination with your gender and age to
`calculate your cardio fitness level. By helping you understand how you compare
`to other people who share your gender and age range, cardio fitness levelIs a
`holistic way to track your cardiovascularfitness overtime.
`
`“ What do the cardio fitness levels represent?
`
`Your cardio fitness score will fall Into 1 of 6 cardio fitness levels that range from
`poor to excellent. These levels are based on published data that help show how
`your cardio fitness score compares to others who are the same age range and
`sex (source).
`
`“ How do!improve mycardiofitness score?
`
`lf your cardio fitness level Is lower than you'dlike, it may be due to several factors
`Including a stationary lifestyle, which could have negative effects on long term
`health like an Increased risk for developing high blood pressure and coronary
`heart disease (source).
`
`The two waysto Improve your score are exercise and healthy weightloss.
`Increased exercise may help you improve your score by up to 20 percent over a
`period of two to three months (see Kennedy, Phys. of Sport and Exer., 2012).

`Specifically, the American Heart Association recommends“at least 150 minutes
`per week of moderate exercise or 75 minutes per week of vigorous exercise (or a
`combination of moderate and vigorousactivity)” to Improve overall cardiovascular
`health (source).
`
`While an Increase In moderate exercise can be helpful, Including high-intensity
`Intervals In your workouts If you're able can be an effective way to see noticeable
`improvement.Interval training Includes any workout that alternates between
`Intense bursts of activity followed by periods of lower Intensity activity or rest.
`Both endurancetraining and Intervaltraining studies showed IncreasesIn
`participants’ VO2 Max, but interval training yielded more significant
`improvements (Source). For more Information on how to use Intervals In your
`workout, see How do | track my workouts with my Fitbit device?
`
`Additionally, healthy weight loss (primarily by lowering your body fat percentage)
`can contribute to an increase In your cardio fitness score. On the other hand,
`unhealthy welght loss (lowering your muscle mass) can have a negative effect on
`your score (source). If you’ve entered a healthy weight loss goal into your Fitbit
`profile, the graph shows the potential improvement to your score. If your welght
`loss goal would lower your Body Mass Index (BMI) into the underweight range,
`potential Improvement to your score won't be displayed. For more Information
`about BMI ranges, see the American Heart Association.
`
`“ How dol get the best cardio fitness score during runs?
`
`If you're running with GPS,try the following tips for the best estimate:
`
`« Go for long runs (at least 10 minutes long) on flat terrain.
`
`«+ Complete multiple runs to help Improve accuracy.
`
`- Run ata faster pace If you're able to do so. You don’t have to run at
