Freya Lindqvist
Writes the test protocols, and runs each one before it is published, which is why several of them carry a note about the way they go wrong in practice rather than in the original paper. Covers VO₂max and race prediction, and reviews the guides for whether a reader with a watch and a track could genuinely follow them.
