VO2 max is a term commonly used by runners to assess your body’s efficiency in processing atmospheric oxygen.
It is the maximum volume (V) of oxygen (O2) in milliliters that you can use in one minute, per kilogram of body weight, while breathing air at sea level. Knowing your VO2 Max is good for those keen on testing and improving on their personal fitness.
Still others will use that piece of information to assess how they compare to others (“standards”) who are doing their same sport. By knowing what your current VO2 Max is, you can objectively assess your progress as you improve your cardiovascular fitness.
