Andy Robertson remembers vomiting the first time he ever did the lactate test. He was 23 years old, had just arrived from Hull and considered himself in pretty good shape. Until, that is, he was made to run Jürgen Klopp’s sadistic pre-season gauntlet for the first time.
Basically, you do laps of the training pitch. The required pace gradually quickens, in the manner of a bleep test. Unlike in a bleep test, however, at regular intervals a member of Klopp’s medical staff will come over, puncture your ear and – ew – extract a sample of blood from it. High lactate levels indicate fatigue; too high and you’re done. Pretty soon Robertson was feeling queasy. He started gagging. Full discharge followed soon after. It may not surprise you to know that James Milner won the Melwood lactate test eight years running.
