549: The largest predictor of longevity we don’t talk about | Performance coach & scientist Andy Galpin, Ph.D.

Lab Methods

Andy Galpin explains that the gold standard for measuring VO2 max involves using a metabolic cart in a research laboratory. This method, though once expensive, is now more accessible and provides the most accurate results. He advises opting for a research facility over local gyms for better calibration and accuracy 1.

Everything from cheap to the gold standard. This is what it looks like. We'll go and reverse order. Gold standard is you have got to go into a laboratory, into a facility, a research laboratory, or a pay for service, one that will allow you to be on a metabolic cart.

Andy also highlights that while genetics play a role in VO2 max, lifestyle and exercise habits have the most significant impact 2.

   

Wearables

Consumer wearables offer a convenient but less accurate alternative for estimating VO2 max. Andy Galpin notes that while devices like the Oura ring provide rough estimates, they can't match the precision of lab-based methods. He emphasizes understanding the limitations of these devices and choosing based on individual needs 2.

There's simply no way a device like an Oura can get you the same level of accuracy as going into a laboratory and getting all of your gas collected in a mask on a $40,000 machine.

For those unable to access lab facilities, fitness centers and longevity clinics offer a middle ground, though they may not always use the highest quality equipment 1.
