The Claim

Endurance athletes have a significantly higher maximal oxygen uptake (VO2max) of 52.4 ± 9.7 mL/min/kg compared to skill athletes (36.3 ± 7.9 mL/min/kg), power athletes (42.0 ± 7.7 mL/min/kg), and mixed athletes (40.5 ± 5.8 mL/min/kg), indicating superior cardiopulmonary functional capacity directly related to the aerobic demands of their training.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Endurance athletes have a higher maximal oxygen uptake than athletes in skill, power, or mixed sports, reflecting greater cardiopulmonary capacity due to their training demands.

See the scientific wording

Endurance athletes exhibit significantly higher maximal oxygen uptake (VO2max) of 52.4 ± 9.7 mL/min/kg compared to skill athletes (36.3 ± 7.9 mL/min/kg), power athletes (42.0 ± 7.7 mL/min/kg), and mixed athletes (40.5 ± 5.8 mL/min/kg), reflecting superior cardiopulmonary functional capacity directly related to the aerobic demands of their training.

Why this might work

Endurance training makes the heart pump more blood with each beat, increases the number of blood vessels in muscles, and boosts the muscle's ability to use oxygen for energy. This allows more oxygen to reach working muscles during intense exercise, raising the maximum amount of oxygen the body can use.

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

    Endurance athletes like marathon runners use way more oxygen during intense exercise than athletes in other sports, and this study proves it by testing thousands of elite athletes. Their hearts and lungs are better at delivering oxygen to muscles because of their training.
