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?

  • Just trying to figure out my biggest shortcoming so I can focus on it, or at least be aware of it. Not sure if it is conditioning, technique or a combination of both. I'm talking primarily free here. Ande and others, Do you ever compare heart rate and heart rate recovery with your lanemates during a workout? What would your peak heart rate be and how quickly does it recover. I would assume the higher the heart rate the better and the quicker the recovery the better. Higher max heart rate is better because you're getting more oxygen to working muscles. That said, higher heart rates might not necessarily be better. If the goal of a set is to swim race pace, then sure, you want your HR up near max. If you're doing an EN1-type recovery set and your HR is up there, it's not so great. Quick recovery is desirable.
