"The findings are contrary to the popular assumption that men's bodies are more naturally athletic," said Thomas Beltrame, lead author on the study.
‘Women consistently outperformed men with around 30 per cent faster oxygen handling throughout the body.’
The study compared oxygen uptake and muscle oxygen extraction between 18 young men and women of similar age and weight during treadmill exercise. Women consistently outperformed men with around 30 per cent faster oxygen handling throughout the body.
"We found that women's muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a superior aerobic system," said Richard Hughson, a professor in the Faculty of Applied Health Sciences, and Schlegel Research Chair in Vascular Aging and Brain Health at Waterloo.
"While we don't know why women have faster oxygen uptake, this study shakes up conventional wisdom," said Beltrame. "It could change the way we approach assessment and athletic training down the road."
The study is published in Applied Physiology, Nutrition, and Metabolism.
