Do Females Have a Superior Aerobic System?

In a small study involving 18 men and women, researchers found that female bodies are more efficient at delivering oxygen to the muscles. Researcher Dr. Richard Hughson explains, “We found that women’s muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a superior aerobic system.” Lead author Dr. Thomas Beltrame adds, “The findings are contrary to the popular assumption that men’s bodies are more naturally athletic.” Applied Physiology, Nutrition, and Metabolism, June 2017
