Does lactic acid accumilate due to poor fitness of the respiratory system or fitness of the muscles itself.
Many “fitness sites state that lactic acid builds up when heart rate rises above a certain percentage of your working hr”
That certainly isnt the case with me and cycling or prowler like exercises. After about a year and a bit of proper training im able to squat more than 2x bw and almost front squat it as well. I carried those maxes into my rugby season where i started off unfit but soon improved to thr point i was one of the fittest ones in the team. In sprints and in burpees as well
However the moment we did any prowler like work or cycling My legs would die. If i jump on the bike and sprint for 10 seconds i would immediately get a painful lactic acid build up which would hinder anything i do afterwards. I cant even jump on the exercise bike to warmup for squats because it would give me lactic acid even at a low intensity low resistance.
Is the only way to cure this just to keep cycling/prowler or am I going to die.
Seriously though, no matter how strong you are, if you push yourself hard your HR will rise to a level where there is not enough oxygen for the energy demands and your body will therefore be forced to utilize it’s anaerobic energy systems (one of which, Anaerobic Glycolysis, produces lactic acid as a byproduct). It doesn’t matter if you have the strongest squat in the whole world, push yourself hard and you will “feel the burn” so to speak.
The cycling is probably because you are just weak in that motion, and possibly because you squat with a hip dominant style (don’t know that for sure, but since cycling is mostly quad dominant and your endurance seems really poor it would make sense). Also, how you perform your weight training will determine how well it carries over to stuff like prowler or cycle sprint work.
If you train really heavy but low reps that’s not going to carry over well. If you train with more moderate weights but high reps (thus building up more lactic acid), stuff like 20 rep “breathing squats”, then you will notice much better carry over.
Maybe you read too much.
You can stop producing that bad acid it is quite simple.
Stop breathing.
Heart rate is irrelevant, there is no reason to mix those 2 subjects and create confusion.
Muscle(s) contraction always generate residues just like burning wood/paper…
Bigger fire more residues, same for that acid.
Sleeping, sitting it is not noticeable but activate muscle(s) more it can be like a big rain and water/acid accumulates.
Geneticaly some have more endurance than others and obviously training might increase our endurance depending how we train.
Im not even sure its lactic acid now. I think my legs just cant handle being under stress for too long no matter the intensity.
Another terrible example of this is that if I sit in a half body weight squat position and stay there for more than 10 seconds I can start to feel a burning sensation. My legs arent sore in anyway as I dont get sore from squats anymore.
Ill remind you that when I was one of the fittest in my rugby team I was also squatting 150kg atg at 70kg. I would still get a burning sensation during any bike rides or prowler pushes but I would be fine during runs and sprints.
Anyway I think I may be able to come up with other ways to cure this disgusting disease occurring in my legs. Maybe do air squats everyday until it feels easier.
You’re still not quite understanding how this works.
It doesn’t really matter how much you can max out on; if you don’t train your legs to deal with and better buffer lactic acid build-up you aren’t going to be good at it.
Try doing some 20 rep “breathing” style squats (basically take a weight that you can get 10-12 consecutive reps with and gut out 20, “resting” at the top of the squat to take a few breaths between reps as your legs fatigue) if you want to do some resistance training that will greatly increase your “lactic acid threshold” while still maintaining your strength.
He’s correct, its a different training effect that the muscle itself will adapt to. Anaerobic efficiency will help shuttle away the byproducts of glucose metabolism faster which is what causes this burn.
Where strength/power training would benefit from the muscles carrying loads of energy molecules and sitting through long rest periods, what you are is after more of an anaerobic endurance. In fact the better adapted you are to strength/power training the more painful endurance activities can be, as you are going to burn through those stored energy molecules faster.
I can squat nearly 500lbs, but found myself utterly dying during a bodypump class at 24hr fitness doing 60lb///bodyweight squats and lunges. It was excrutiatingly painful and embarrassing, if the female presence wasnt high, I swear I would have limped out. I find that when you are used to recruiting as many motor units as possible you will do so as you move whether bearing hundreds of lbs or nothing.

It takes time to make muscular endurance adaptations. The lance armstrong marathon example illustrates this. His aerobic endurance, v02 max etc… were all at levels that should have made it easy for him to place higher than he did. But cycling has a much different muscular demand than running so his numbers weren’t spectacular but were still good, meaning there was some carryover.
Also remember while I can run intervals till I puke and it’s working the glycolytic system heavily if I did squats for 50 reps I will still work the glycolitic zone hard but the response to my quads is going to be greater. Lastly your question on aerobic endurance is basically yes the more aerobic endurance the longer the time before your heart rate crosses into the upper thresholds and you start building up lactic acid. If you were to examine any middle distance runners training, they still do a lot of aerobic work for this reason.
