Runner's World published a story explaining how bodyweight impacts VO₂ max metrics featuring insight from Kate Baird, MA, ACSM-CEP, CSCS, exercise physiologist at HSS.

VO₂ max is widely regarded as a gold standard of aerobic fitness. It shows up on watches, in training apps and across social media as a benchmark for comparison. But the number that you’re seeing might not present your fitness level as accurately as assumed. Research questions whether the most common way that we measure VO₂ max – that is, based on bodyweight – actually provides the best way to compare aerobic efficiency across different body types. 

Elite marathoners tend to have high relative VO₂ max values, partly because of their smaller, lighter frames, said Baird. Meanwhile, athletes like rowers, who typically carry more muscle mass, often post lower relative VO2 max numbers than marathoners, even though their absolute readings may be larger.

Baird stressed that for most people, runners included, simply being active and maintaining a well-rounded routine is far more important to both your aerobic fitness and your overall health than trying to optimize this metric—or trying to manipulate your way to a better score. 

Consulting with a medical professional is essential for understanding your full set of health metrics and optimizing both performance and overall wellness. Learn more about performance services at HSS, including VO₂ max testing, here.
