WHAT IS MAX VO2? WHY IS IT SO IMPORTANT? HOW DO YOU IMPROVE IT?
1. What are some different levels of VO2 max, and what do these numbers mean?
VO2 max values, typically expressed in ml/kg/min., can vary between 20 and 90 ml/kg/min. The average value for a sedentary American is about 35 ml/kg/min, while elite endurance athletes average about 70 ml/kg/min. Your sedentary VO2 max value is primarily determined by genetics (a sedentary person may have a VO2 max value as high as 50 ml/kg/min. or as low as 20 ml/kg/min). Although anyone can improve their sedentary VO2 max value through training, this genetic variation helps explain why everyone can't train themselves to be elite.
2. What are some of the highest levels of VO2 max ever recorded?
The highest VO2 max value ever recorded, 93 ml/kg/min, was from a Scandinavian cross country skier. Steve Prefontaine, at 84.4 ml/kg/min, had one of the highest VO2 max values recorded in elite runners. Grete Waitz had a VO2 max of 73 ml/kg/min. when she was running at her best, one of the highest recorded values for women and on par with the values for some elite men.
3. How do some elite runners make up for lower levels of VO2 max?
Although all elite runners have VO2 max values well above the population mean, the correlation between VO2 max and performance is not absolute. Derek Clayton only had a VO2 max of 69 ml/kg/min. and Frank Shorter only recorded a value of 71 ml/kg/min., yet both of these runners ran marathon times of under 2:11 and surely outperformed runners with higher values. This variation in VO2 max values among the elite is possible because VO2 max is only one of several factors that determine running performance. These other factors include mental attitude (ability to tolerate pain), running economy (how efficiently one runs), and lactate threshold (fastest pace you can maintain without accumulating large amounts of lactic acid in your blood). A runner with a relatively low VO2 max, but high in these other performance factors, could outperform a runner with a significantly higher VO2 max but with poor running economy and a low lactate threshold. For example, Derek Clayton and Frank Shorter compensated for their lower VO2 max values with their high efficiency and ability to run their marathons at a high percentage of their VO2 max without accumulating too much lactic acid (high lactate threshold).
