I find the LT graph interesting and it makes sense, because with the increase in HR would also mean an increase in VO2, which more lactate would build up.

@philosopher43932 жыл бұрын
Thanks Doc. Does the lactate threshold follow a concept similar to progressive overload where you might have to train slightly above it to improve your tolerance of lactate? Like how we have to stress our muscles beyond what they are used to in order for them to grow.
@keeganreynolds19592 жыл бұрын
Usually athletes increase the volume of work at lactate threshold, or use longer repetitions, to progressively overload LT. Additionally athletes will increase the pace of their repetitions or tempos as their lactate threshold improves to match where their current ability is. An example of a progression for a distance runner might be something like: Session 1: 5x5min @LT effort w/60 seconds rest Session 2: 6x5min @LT effort w/60 seconds rest Session 3: 3x10min @LT effort w/60 seconds rest Training above your lactate threshold will still give you benefits and increase your threshold, as your body is still utilizing that energy system at a faster pace. However the adaption won't be as strong towards your lactate threshold, and you will have an increased recovery time because of the higher intensity. I realize this is an old comment but I hope it helps nonetheless!

Beats me! But my best guess is that the "burn" you feel during lactate build-up is similar to the "toastiness" of your muscles when experiencing DOMS.

If an athlete is producing too much lactate for the liver to be able to convert to glucose, where does the lactate enter the bloodstream from? does it enter straight from the liver or will it enter the muscles still, and then enter the blood?
@DrJacobGoodin3 жыл бұрын
It just stays in the muscle cell or in the blood stream, waiting to be cleared. If levels get too high, not only does that little voice in your head scream at you to stop, but eventually some sort of central governor (depending on who you ask) limits output to the muscles, causing you to slow, so that the Cori cycle can work on clearing the buildup.

Do you train right under your lactate threshold each practice session or does it vary?
@DrJacobGoodin3 жыл бұрын
It definitely varies. For distance runners and middle distance runners, there are specific training sessions that focus on lactate threshold training, but a host of other running paces and interval combinations that still help enhance it to some extent, while their primary focus might be other aspects like aerobic endurance or VO2max.

@DrJacobGoodin3 жыл бұрын
So you can measure it directly like I was saying to Abner, or you can gauge it through a few different attempts. Lactate threshold _typically_ corresponds with between 70-80% of max heart rate. So if you calculate max heart rate, then throw on a heart rate monitor and keep HR in that zone, you'll be in the right ballpark. You know you're going too fast if you cannot maintain the pace for 15-20 minutes, or up to about 30 minutes for more well-trained individuals. You should feel fairly uncomfortable the entire time and like you can only get out 1-2 word sentences
