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. You can use your Garmin^® device paired with a compatible heart rate monitor and power meter to display your cycling VO2 max. estimate.
