Maximal oxygen uptake, or VO2 max, is perhaps the single best predictor of long-term health and longevity. It’s also the key trait that distinguishes elite endurance athletes. We know all this from more than a century of research… in men. Whether the same things hold true for VO2 max in women is less clear, because there simply isn’t as much data on them.
A new study from researchers at the Federal University of São Paulo in Brazil aims to fill some of this gap. They recruited 85 runners and 62 sedentary people, all women between the ages of 20 and 70, and split them further into younger (less than 50) and older (greater than 50) age groups. Then they tested their VO2 max with a progressive treadmill test to exhaustion, measured their body composition with a DXA scan, and collected information about their training and other health-related habits. The results are published (and free to read) in Experimental Gerontology.
The headline findings are unsurprising: runners had higher VO2 max than non-runners, meaning they were able to suck in, distribute to their muscles, and use more oxygen per minute; younger people…
