Exercise is amazing Master Therion, what do you mean? What gives if lactate and some muscle soreness results, it's good for muscle growth! Just like the protein and calcium in milk, except don't drink it if it has the smell of lactic acid! If you do, your intestines and anal sphincter may suffer from "exercising" constantly for days on end... #LacticAcidMuscleSorenessInTheGutIsReal I'm sorry if that one was really bad, food poisoning IS NOT funny. I've had it.
I just wanted to say as someone that is currently studying to be a personal trainer with the National Academy of Sports Medicine (NASM) - they have in their official textbook that lactic acid buildup is what causes muscle pain, so this video is super timely! Thanks for setting the record straight, I prefer to have the most up-to-date scientific information! NASM needs to get their ass in gear
well, from what i research and still research lactic acid divides in blood in lactate and H+ ,because lactic acid is unstable and it disipates rapidly in the blood. So while in muscle ,H+ make muscle more acidic and lactate is a direct measure of of H+ ions in the blood and the fact that muscle is acidic iritates nevres and transmit the sensation of pain.Practicly kinda this is the lore.
@@GDM1787 Clearly you couldn't be bothered to read any of the scientific research they're using to explain this. 🙄 Even my A&P professor outright said that the "lactic acid" myth in the textbook was wrong and current science proved it, and that was back in 2007. If you haven't read through the research that's even being quoted, you need pause before commenting.
Teachers teach the curriculum. Even if it's wrong. I was taught that the sky is blue because of the oceans and asked the geography teacher if we could ask the physics teacher about it... but he replied (after a prolonged discussion) that he was forced to teach us what the book says (the curriculum).
@@turtle2720 im pretty sure he didn't only do that but also thought us many things that were just cool to know. He told us much about abiogenesis (how the first life propably started) because he said he wanted us to know even though it isnt in the curriculum
muscles tearmicroscopically when they are overused, then they heal stronger, exercise is basically tearing down your body and renovating it slightly better thousands of times.
You are supposed to blame everything on the new guy at work. That or Congress, the president, minorities, religious sects, atheists, homosexuals, the government, vaccines, GMOs, gravity. Anything but yourself.
TheCimbrianBull I’m “that” guy. Whenever I hear someone say a misconception I pop in and say “um actually.” But it’s only when I actually know about it.
Thank you Hank for all of your awesome videos, years of interesting, in depth and thought provoking content and most of all for spreading critical thinking and educating people!
I need a gif of 3:28 : "We have to be accurate, but don't be condescending!" ... And the sparkly text - I love it! Or even better mugs, Tshirts, EVERYTHING!
I'm an runner and a LOT of the older publications push the lactic acid theory. Only recent publications stop talking about lactic acid and now just refer to 'acidosis' . Big thanks for publishing this.
Tips from a former high school student: Look up the general definition of “foundationalism” and you’ll be already ahead of most entry level college courses.
pretty amazing that we dont even know what really causes muscle fatigue! im pre-med so from what ive learned, i gathered it was caused by torn up myosin fibers that were in the process of rebuilding to support stronger/longer muscle contractions. Sort of comparable to how when an individual experiences a bone fracture/break, the bone rebuilds itself even stronger than it was previously!
I tihnk lack of ATP is still the problem. A braking effect on generation of new ATP due to localised saturation with unwanted waste molecules is still the most likely cause. The only difference is that lactate is not the braking molecule. The hunt is on to find the culprit.
I read somewhere years ago, that muscle soreness was actually caused by calcium. When calcium comes in contact with an open wound (i.e. micro muscle tear) from the exercised muscle, it causes an inflammatory response, which also puts pressure on the surrounding nerves of the muscle trying to protect it.
This was incredibly illuminating! I have ALWAYS blamed the lactic acid, and I am 42! Hank-I will try, really hard, not to be pedantic when I explain this to people from now on...maybe I will just tell them to watch SciShow!
This reminds me of another episode I'd love to see. Some years ago I saw something that stated that the accepted doctrine of fluoride strengthening you teeth was based on a single, faulty study. Personally, I don't see how something that leaches calcium from bodes would protect your tooth enamel. PLEASE do something on this.
Thank you for the PSA about not being condescending. It happens more often than I'd like to admit, I'm guilty of it many times and it's a very good thing to keep in mind as people typically don't like to be told they are wrong.
In school I was taught that lactic acid causes pain in the muscles if you suddenly stop exercising, hence the need for a cool down. I'm assuming a cool down is still needed, but can someone tell me why if it isn't to release the lactate back into the blood stream slowly?
Tamara Epps I think cool downs help flush the acid ( the protons) out of the muscles to kind of restore the ph and help u recover faster, and they keep ur muscles from tightening up so much so u stay loose
tl;dr to keep blood moving to make tired muscles happy. I'm not sure if this is another "exercise myth" but I believe cooling down allows the blood to keep moving through the body while the heart is returning to normal. Arteries are high pressure, the heart is what moves blood through them. But veins are low pressure. Veins (at least partially) rely on the movement of skeletal muscles and one-way valves to move blood. So if you suddenly stop exercising blood can pool in the muscles (especially the legs) which is bad because the muscles are starved for fresh oxygenated blood.
Yeah, and not only cooldown helps with the pain, once you’re feeling pain days after, you can exercise your normal routine but now with proper cooldown at last and alleviate the pain. It doesn’t make sense to me if damaged tissue were responsible for the pain. Unless, oc, if you have a other kind of lesion. I heard once that unused crystals left behind by the biochemical processes were responsible for the pain. So by exercising again to some point your body consumes the crystals.
I work out a lot 6 times a week how i view a cool down is more of a aerobic exercise like running or doing circuit exercise were u do light weight high reps rapid pace for 10 minutes or more and working different muscles. That's what i use that for. going slower when I'm done with main work out like for my jog or circuit work out i do after im done, it helps my body get back to normal from hi blood pressure lowers my breathing tells my, Muscles your getting ready for normal day to day activity veins decrease in size and i feel calmer, lactic acid i like becuase ik im using my stored energy food from stomach and fat cells, but feeling muscle soreness takes 2 to 3 days to feel the effect for me. But if you r a beginner feeling muscle soreness ull feel more often like 12 hours after or 24 hour's after you work out if you work out for so many days for long period of times the rate of muscle soreness will go down or to not at all. if u don't feel anything and had a good work out which i mean by good workout is working till muscle failure u have built up a tolerance but if no muscle pain after work out means u didnt properly work then out, cool downs from what i experience don't help muscle fatigue but helps body to get back into natural rhythm
The cool down is needed because the body doesn't handle sudden big changes very well. Have you ever tried running very fast for some time and then suddenly stopping? you most likely will feel sick. Same reason of why there is a warming up period.
I was literally about to join Patreon to ask you to do a video on this. One of those physiological misconceptions that triggers the sport scientist in me everytime I hear it.
I think a video on what we really DO know about how the body works, would be really useful. And it would be short. It would go something like “people who eat less seem to weigh less, and people who weigh less, seem to live longer. The rest is commentary. Also we have no real idea.”
Speaking of personal trainers. I had one tell me I was 80 pounds overweight because I was starving myself; that I was in the classic starvation mode. I told her she was a damn idiot and stopped being a client.
Correlation =/= causation. Easy enough to understand. Like if a bitter person is on a panel at a convention and just because someone they don't like is sitting quietly listening doesn't mean it's the quiet persons fault when the panelist starts insulting and harassing them. Got it!
Some time ago i saw a program where they put an ultra-marathoner on a treadmill. This person does dawn to dusk runs for FUN! While on the treadmill they measured his lactate (acid?), and as he ran longer and longer the measurement went down!
haha the "don't be condescending" was a good reminder, as I sit watch and imagine telling people when they complain of the lactic acid build up in their legs
When is there going to be a Crash Course Exercise Science, Nutrition and Health? Something that cover the physiology, biochemistry, and psychology, of exercise as well as general nutrition. Not to mention, includes pathology of common diseases such as Myocardial infarction and hypertension.
Technically the protons are created in the glycolysis but this produces only 2 ATP. So without oxygen you don't get the extra 30+ from the mitochondria. Conclusion: the path without oxygen produces more H+ per ATP.
True, lactate doesn't cause muscle soreness. But it is created through exercise.
Which is why I don't exercise. I'm lactate intolerant.
I know your are joking, but even at rest, we all have some lactate in our blood.
that's pretty good. haha.
BaHahahahahahaha
Made me laugh, 👍
