Performance enhancement to Phelps and Armstrong levels

Could we genetically our ability to withstand lactate or boost our efficiency at removing lactate from the cell and processing it.

There are couple of high-performance phenotypes related to lactate. It is rumored that Lance Armstrong could withstand lactate measured at 24. Many people would be unable to stand with lactate measured at 16. It is rumored that Michael Phelps could process lactate (lactic acid) super-efficiently. Phelps could set world records and be measured with lactate at 8.

Joe Rogan and Peter Attia discuss performance enhancement.

It is more healthy to perform the Tour de France on steroids. The Tour de France wrecks competitors health.
