The Claim
Female endurance athletes have a maximal oxygen uptake (VO2max) of 52 mL/kg/min, which is 33% higher than the VO2max of 39 mL/kg/min observed in non-athletic female controls, indicating superior aerobic capacity associated with long-term endurance training.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Female endurance athletes have a 52 mL/kg/min maximal oxygen uptake, while non-athletic women have a 39 mL/kg/min maximal oxygen uptake. This difference reflects a 33% higher aerobic capacity in athletes due to long-term endurance training.
See the scientific wording
Female endurance athletes have a 52 mL/kg/min maximal oxygen uptake (VO2max), which is 33% higher than non-athletic controls (39 mL/kg/min), reflecting superior aerobic capacity consistent with long-term endurance training.
Long-term endurance training makes the heart's main pumping chamber larger and more efficient at filling with blood between beats. This allows the heart to pump more blood with each beat, delivering more oxygen to the muscles during intense exercise, which raises the maximum amount of oxygen the body can use.
What the research says
1 studyStudy: Female athlete's heart: Systolic and diastolic function related to circulatory dimensions
The study found that female athletes can use 33% more oxygen during intense exercise than non-athletes, which is exactly what the claim says. Their hearts are also bigger and work better, helping them perform better.
