About VO2 Max. Estimates

VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body
weight at your maximum performance. In simple terms, VO2 max. is an indication of athletic performance and
should increase as your level of fitness improves. The Descent Mk2i device requires wrist-based heart rate or a
compatible chest heart rate monitor to display your VO2 max. estimate. The device has separate VO2 max.
estimates for running and cycling. You must run either outside with GPS or ride with a compatible power meter
at a moderate level of intensity for several minutes to get an accurate VO2 max. estimate.
On the device, your VO2 max. estimate appears as a number, description, and position on the color gauge. On
your Garmin Connect account, you can view additional details about your VO2 max. estimate, including your
fitness age. Your fitness age gives you an idea of how your fitness compares with a person of the same gender
and different age. As you exercise, your fitness age can decrease over time.
