The geometry of superior athletic performance
The article discusses the significance of VO₂max, a key indicator of athletic performance and overall health. It compares human endurance capabilities with those of other species, particularly sled dogs, which exhibit superior VO₂max values. The piece highlights the evolutionary adaptations that contribute to these differences in oxygen consumption efficiency.
- ▪VO₂max is a critical measure of oxygen consumption during peak exercise and is a strong predictor of mortality.
- ▪Elite athletes, such as cross-country skiers, can achieve VO₂max values as high as 96 ml/kg/min, surpassing other sports.
- ▪Sled dogs have an extraordinary VO₂max that can reach up to 240 ml/kg/min, significantly higher than human athletes.

The Geometry of Superior PerformanceCube–Square Scaling and Comparative VO₂max Across SpeciesNick MarkMay 27, 202631ShareVO₂max - the maximum rate of oxygen consumption during peak exercise - is one of the most informative numbers in physiology. Among athletes, physiologists, and intensivists alike, it functions as a kind of summary statistic for the entire oxygen delivery cascade: how well the lungs extract oxygen, how efficiently hemoglobin carries it, how powerfully the heart pumps it, how densely the capillaries deliver it, and how effectively mitochondria consume it. Each step is potentially rate-limiting, and VO₂max tells you how well the entire oxygen cascade functions.
