Women ‘naturally’ more fit than men
December 14, 2017, 2:59 pm

Women engaged in exercises process oxygen more quickly than men, says a new study by a team of specialists at the University of Waterloo in Canada. The findings are contrary to the popular assumption that men's bodies are more naturally athletic.

Quick oxygen uptake places less strain on the body's cells and is considered an important measure of aerobic fitness. The study compared oxygen uptake and muscle oxygen extraction among men and women of similar age and weight during treadmill exercise. Women consistently outperformed men, with 30 percent faster oxygen handling throughout the body.

The research team said they found that women's muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a superior aerobic system. By processing oxygen faster, women are less likely to accumulate molecules linked with muscle fatigue, effort perception and poor athletic performance.

While it is still not clear why women have faster oxygen uptake, this study shakes up conventional wisdom and could change the way in assessing fitness and athletic training in future.
