For a long time it has been believed that men are physically stronger and fitter than women, but a new study found that when they start exercising, women are more fit, as they can process oxygen faster than men.
Researchers at the University of Waterloo found that women can process oxygen faster than men when they exercise, since rapid oxygen uptake exerts less pressure on body cells and is considered an important measure of aerobic capacity .
Lead author Thomas Beltrame said the findings are contrary to the popular badumption that men's bodies are more athletic.
The team compared oxygen uptake and muscle oxygen extraction among 18 young men and women of similar age and weight during tape exercise.
The results suggest that women consistently outperformed men with 30 percent faster oxygen throughout the body.
Another researcher Richard Hughson said that women's muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a higher aerobic system.
processing oxygen faster, women are less likely to accumulate molecules related to muscle fatigue, perception of effort and poor athletic performance.
"While we do not know why women have a faster uptake of oxygen, this study shakes conventional wisdom," said Beltrame.
The study is published in Applied Physiology, Nutrition and Metabolism.  (With entries from the Agency)
