Which Sex Is The Better Natural Athlete?

Looks like women are better natural athletes than men. A new study from the University of Waterloo in Ontario has revealed that, when exercising, women process oxygen 30 percent more efficiently than men. This faster oxygen uptake indicates a greater level of fitness and also results in less muscle fatigue. Study author Professor Richard Hughson said, "We found that women's muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a superior aerobic system." (Daily Mail)
