It’s hard to get too far into reading about training without encountering the phrase “vo2 max” or hearing about “VO2 max testing.”
But what is VO2 max and how does it relate to runners?
When VO2 max tests were largely the focus of academic studies, the concept of max VO2—something rooted in physiology—didn’t seem that important to your average runner.
It was something that elite runners and researchers could worry about.
But now there are private companies and academic labs all over the place offering to do VO2 max tests on runners and cyclists of any ability level to aid their training.
Many GPS tracking devices now provide a VO2max number.
But, how do we define VO2 max? Should you pay for a lab test to find out what your VO2 max is? Is the reading from a GPS device even accurately able to measure our aerobic capacity?
