Who among us hasn't marvelled at Paul Tergat's speed in the marathon or Lance Armstrong's power in the Alps? What we're really admiring - from a scientific viewpoint, anyway - is these mega-athletes' VO2 max, one of the best indicators of aerobic

and coaches generally agree that there are three ways to improve running performance: you can increase your maximum oxygen uptake, or VO2max, which measures the greatest volume of oxygen that can be dispatched to your muscles during exercise; you can extend
to get faster. But there are several different ways to improve average race velocities. For example, increasing VO2max (maximal aerobic capacity) improves race speeds, because as VO2max rises, your previous race speeds will correspond with a lower
VO2 max - the measure of how much oxygen your body can get to your muscles - has tended to grab all the headlines when it comes to evaluating endurance running performance. After all, it's relatively straightforward to measure, gives quantifiable

oxygen-delivery machines who know their VO2 max and use the impressive numbers to bolster their confidence. Armstrong knows his VO2 max, too. His long-time friend, confidante, and coach, Chris Carmichael, has had his star pupil tested on several occasions
of Medical Science for Sport and Exercise showed that speed at lactate threshold is the best physiological predictor of distance-running performance. Indeed, Frank Shorter, the 1972 Olympic marathon champion was said to have had a modestly high VO2max
. A study published in Medicine & Science in Sports & Exercise found that the longer subjects walked at 70 per cent of maximal oxygen consumption, or VO2 max, the longer it took for their metabolic rates to return to their pre-exercise levels
