So why does all this science matter and what does it mean for you? First of all, VO2max is the strongest independent predictor of future life expectancy so everyone out there should be at the very least slightly interested in their own value, athlete or not. Additionally VO2max  becomes especially useful once we consider its impact on athletic performance. 

In order to walk, run or move at all, our body needs to produce energy; we can either produce this energy without oxygen (anaerobic) or with oxygen (aerobic). Any exercise will require energy production from both aerobic and anaerobic systems however their relative contribution is determined by the duration and intensity of the effort. As anaerobic energy production is only possible for a very short period of time, our bodies will always try to meet the energy demands aerobically. In trained individuals it has been shown that during a maximal effort the switch to predominantly aerobic energy systems occurs somewhere between 15 and 30 seconds into exercise as by this point we have “run out” of anaerobic fuel. The rate of work, power output or running pace that an individual can maintain aerobically is determined largely by their VO2max.
