Elite athletes may have a higher glycolytic capacity or be so efficient they produce very little lactate.

“And that's because, and we can talk about that later, their glycolytic capacity, it's off the charts. Whereas people who they're not elite athletes, it's for them that's in protocol. It's more difficult to go over 12 millimoles, 10 millimoles, because their glycolytic capacity is not so good as the one that the elite athletes have. And sometimes elite athletes... have the opposite issue, which is they don't make much lactate at all. They're so efficient.”
