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.
On the device, your VO2 max. estimate appears as a number and description. On your Garmin Connect™ account, you can view additional details about your VO2 max. estimate.
