lactate testing as a measure of swimming efficiency

Two swimmers test their blood lactate and they are at the same level. One swimmer holds a 60 sec/100 pace and the other holds 75 sec/100 pace, is it fair to say swimmer one is swimming more efficiently, or are there other factors such as physiology at play? Can the swimmer with higher lactate still actually be swimming more efficiently, yet be generating the higher lactate numbers? How do you pinpoint where a swimmer's physiology is limiting their performance and not their technique?

  • I would think that it would be difficult to just compare a number between two people, and come up with a conclusion. Maybe it could be figured out with a set of points for each person (like resting, moderate effort, full effort). I could imagine one person having low lactate levels with their body flushing it, and another person having higher levels from being able to exert more (useful) propulsive energy.
