VO2 Max Emerges as Key Longevity Marker as Women Lose 10% Per Decade After 30

2 articles · Updated · HuffPost · Jun 10

VO2 max—the amount of oxygen the body can use at maximum effort—is gaining attention as a stronger gauge of fitness and long-term health than many routine checkup markers.
A 2026 study linked below-average aerobic fitness to higher anxiety risk, while specialists said higher VO2 max is tied to lower cardiovascular disease risk, better brain function and greater resilience to stress and cognitive decline.
Women lose about 10% of VO2 max per decade after age 30, adding urgency to tracking and improving the measure over time rather than chasing a single universal target.
Lab treadmill or cycling tests remain the gold standard, but doctors said online walking-based calculators and devices such as Apple Watch Series 3 or later and some Garmin watches can estimate it.
Experts said the priority is moving out of the bottom 20% for your demographic and raising your own baseline with moderate-to-vigorous aerobic exercise as you age.
