Women Are Naturally More Fit Than Men, Study Shows
Contrary to expectations, young women showcased quicker V̇O2 dynamics during submaximal treadmill exercise compared to men, challenging prior beliefs about gender differences in aerobic system dynamics.
Contrary to popular beliefs that men's bodies are naturally more athletic, a recent study led by Thomas Beltrame reveals that women have a more efficient oxygen uptake system. This is crucial as quick oxygen uptake means less stress on body cells, marking a significant indicator of aerobic fitness.
In the study, 18 young men and women of similar age and weight were assessed during treadmill exercises. The results consistently showed women outpacing men by approximately 30% in terms of oxygen handling throughout their bodies. Richard Hughson, a professor at the Faculty of Applied Health Sciences, noted, "Women's muscles extract oxygen from the blood at a faster rate, implying they possess a superior aerobic system."
This efficient processing of oxygen ensures that women accumulate fewer molecules associated with muscle fatigue, thereby enhancing their athletic performance. While the reason for this difference remains unclear, Beltrame suggests that these findings could revolutionize our understanding of gender differences in athletic capability, potentially reshaping future training and assessment methods.
