Lactate tolerance

In this thread Fortress said: Interesting Race Club thread. There was one post concluding that lactate tolerance was the key for the last 15 meters of a 100, not aerobic capacity. Which leads to something I've been thinking about lately. I'm sure we've all had races where you try to give it everything you've got at the end and you absolutely turn to jello. I assume this is the lactic acid kicking in. When it hits you slow down very quickly. So how can we train to improve that tolerance? Here's an article by Genadijus Sokolovas on the USA Swimming website: www.usaswimming.org/.../ViewMiscArticle.aspx In it he talks about lactate tolerance type sets: Anaerobic Metabolism (Anaerobic-Glycolitic) is the non-oxidative process of recycling of ATP from glycogen. Glycogen is stored in the muscle cells. Glycogen fairly rapidly recycles ATP, but it is slower than from CP. Anaerobic metabolism produces lactate. It is the main energy system for exercise bouts of 30 sec until 3 min. When distances are longer, aerobic metabolism predominates. Anaerobic metabolism has high power, middle capacity, and low efficiency. Examples of swimming sets and distances that develop anaerobic metabolism: distances of 50 to 300 M/Y, high intensity swimming sets with a short rest interval (i.e., 6-16 x 25 M/Y, 4-8 x 50 M/Y, 2-4 x 100 M/Y, 2 x 200 M/Y with rest interval 20-30 sec etc.). Anyway, I'm finally getting to my point here. The standard way to do this is using fixed sets like this, but has anyone tried something like swimming absolutely all-out until you hit that lactate "jello" feel where you feel yourself slowing down? At that point maybe do some very slow "active rest" swimming then repeat, etc. The goal being to build up the time/distance you can keep up that all-out speed. It seems like actually confronting that lactate wall like this would be a great way to help with lactate tolerance in races.

  • I tried this set on Sunday. I train SCM so I set 2:30 intervals for myself. I think I went out a bit hard in the first set of 4x150. It resulted in a not-so-fast first 200, but I slowed down a lot on the recovery after that and my times picked up. Anyway, I managed the intervals quite comfortably but never got to feel that 'jello' feeling in my muscles. I pushed the third 200 particularly hard and came within a hair's breadth of vomiting but, still , no sore muscles. My fourth 200 was 5 seconds slower than my third and it took all my willpower not to bail after at the 100m mark! So I am wondering if I did it wrong. Why didn't I get that jello feeling in my muscles and rather got the puking sensation? It seems that it was more of an aerobic than a lactate set for me. Today I did a 200 all out for time and on the final 25 my arms 'went jello' but the time I did today was much faster than anything I did on Sunday. I don't really understand the "puking" vs "jello" descriptions. If you felt like vomiting and died to the point where the last 200 was 5 seconds slower than the previous one, I'd say you were well above your lactate threshold so this was in no way an "aerobic" set. Probably your lactate did not spike to the same degree as it did in the 200 all out. Were you within 10 seconds of your best recent rested swim? What was the time difference between your "all out" 200 and your repeats? There should not be much difference between the two, the 200s in the set should be close to all out. To give you a frame of reference: I held mid-1:53s on the set from a push, almost even-splitting (56/57). My best rested time this year was a 1:44. At an unrested meet last fall I went a 1:49 (though it turns out I was getting sick...still, I don't see myself going faster than 1:48, MAYBE 1:47, during the season). I do think of this set as training more for the 500 than the 200, if that helps at all.
