Women are naturally fitter than men, new research reveals.
Females process oxygen 30 percent more efficiently than their male counterparts, a study found.
Quick oxygen uptake is a measure of fitness and associated with a reduced risk of muscle fatigue.
Study author Professor Richard Hughson from the University of Waterloo in Ontario, said: ‘We found that women’s muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a superior aerobic system.’
Lead author Professor Thomas Beltrame added: ‘While we don’t know why women have faster oxygen uptake, this study shakes up conventional wisdom.’
