POWERFUL LUNGS

A 2017 CANADIAN study of young female athletes found that women process oxygen faster than men and absorb it more quickly into the bloodstream. This practice — called oxygen intake — is one way of calculating aerobic fitness. The researchers, who asked participants to walk on a treadmill, found females breathed in air 30 per cent faster than males and that their muscles extracted oxygen from the blood at a higher rate. Not only does this give them superior lung and heart health, but it means women are less likely to experience fatigue after a difficult workout.
