The Claim

Power athletes have a higher maximal oxygen uptake (42.0 ± 7.7 mL/min/kg) than mixed athletes (40.5 ± 5.8 mL/min/kg), but the difference is small and shows substantial overlap, indicating that the current ESC classification does not adequately distinguish these groups functionally.

Description
1 study reviewed
In plain English

Power athletes have a slightly higher maximal oxygen uptake than mixed athletes, but the values overlap significantly, meaning the current ESC classification does not reliably separate these groups based on aerobic capacity.

See the scientific wording

Power athletes demonstrate higher maximal oxygen uptake (42.0 ± 7.7 mL/min/kg) than mixed athletes (40.5 ± 5.8 mL/min/kg), but the difference is small and overlaps substantially, suggesting that the current ESC classification may not adequately distinguish these groups functionally.

Why this might work

Both types of athletes have hearts that pump similar amounts of blood and muscles that use oxygen at nearly the same rate during maximum effort, so their oxygen use numbers overlap too much to tell them apart based on this measure alone.

  1. Study: Cardiopulmonary Exercise Testing in Elite Athletes: Rethinking Sports Classification

    Power and mixed-sport athletes have almost the same ability to use oxygen during exercise, and many individuals from both groups fall in the same range — so telling them apart just by this one number doesn’t work well.
