Here's an image from the legendary coach Jack Daniels in the 1960's.
He is collecting expired air from a runner during a track session.
As you will note, there is no fancy portable VO2 technology used. Just a Douglas bag, a car and manual calculations.
We sport scientists don't know how lucky we have things these days!
