- Why do our muscles get tired and sore after exercise? Explore how our muscles function, and how you can exercise longer without experiencing muscle fatigue.
--
You're lifting weights. The first time feels easy, but each lift takes more and more effort until you can’t continue. Inside your arms, the muscles responsible for the lifting have become unable to contract. What’s going on? Christian Moro explains how exactly our muscles operate, and what causes them to become fatigued.

Slight correction:
Lactic acid isn't a waste product. As of 2018, it's now taught lactic acid is an anaerobic "fuel source." As less athletic people used it less efficiently, more was found in their muscles, leading early physical science to think it was a correlation to waste byproducts.
It was in fact absent from fit people not because they don't produce a mythical byproduct, but because they burnt a higher percentage of the useful, anaerobic lactic acid.
This has been taught for a decade, but it has only been taught mainstream for the past 3 years, so I don't blame you for getting it wrong. Never stop learning!
This is really interesting because I learned lactic acid was waste.
So, the muscles re-use it as fuel source, is that it?
@@Maob08
Much is still being discovered about lactic acid, but basically, it acts as oxygen when your muscles have used all of it's oxygen up.
@@Maob08 I learned, that lactic acid can only be used by the myocard as energy, is that still true? Also lactic acid stimulates fibroblasts to produce more collagen tissue after an injury.
Thanks for saying something and not at all explaining what it actually is then. Just saying “hey actually that’s wrong” no “instead it’s actually”. You would be a great teacher.
@@santi_super_stunts2573 created in the anaerobic lactic energy path way (10secs-3minsintensiveoutput)after glucose breakdowns atp, pyruvic acid, nadh & hydrogen is formed(acidity causing), pyruvic acid takes hydrogen turns into lactic acid and attempts to clear it so the muscles can continue to contract, until the pount there is to hydrogen production against pyruvic acid effecting muscle contraction mechanism and enzymetic function
As a Bio major, I love how simple and entertaining y’all make this process! It can get super complex super fast, but this basic overview is awesome at hitting the big picture points. Thanks for all you do!
Would a increased dietary intake of potassium, ion, and calcium reduce the muscular fatigue I'm experiencing from my new physical demanding job, or do I just have to keep working hard and get bigger muscles?
@@druncle1977 you probably already get enough of them. you need to get stronger and bigger if you want your job to be easier. so try working out, it is amazing :)
@@808Efe I simply don't have the energy at all after work. It's very physical demanding, but already packed on some muscle from it. I tried drinking a smoothie with milk, banana, oats, spinaches, and kale. Seemed to do wonders for me. Didn't drink it today, and was back to my usual exhausted mode.
Muscles: *fatigued*
Every "certified" fitness trainer and HS coach: L A C T I C A C I D
Most of the time people stop doing a certain workout not because of fatigue but because of pain caused by lactic acid
@@aymaneelansari6183 But that's what the while video is about. It doesn't work like that. Lactic acid doesn't cause pain, it likely reduces the pain
@@aymaneelansari6183 Where did you find this? I linked a study from pubmed
@@aymaneelansari6183 not gonna disagree w you but my personal experience has always been that the muscles don't respond way before any feeling of pain. That's with both weights and with running. Extreme high reps or over 4 miles running is a different story however. That's when I start to get lactic acid build up.

As a Biology student, I admit, these videos are a very good way to understand and remember the concepts
When people lift VERY HEAVY, they are training their nervous system more than their muscle. Lifting real heavy, low rep, won't cause so much size increase, but will greatly increase strength though conditioning the nervous system to work more effectively.
This should be pinned. So that's how strength training works.
I have learned it is the other way around - heavy and low rep = bigger muscle but not so much strength increase
@@Theiserino What are you calling low rep? How much volume, how many sets?
@@rodgerbane3825 6-8 reps, 4 sets, what do you mean by volume?
@@Theiserino Number of sets. By very heavy I was thinking 2-4 reps. But hey, I'm just going by what I've been told and read, I am no hulking beast by a long shot.

The part of the Ca job on Tropomyosine and Troponine though, I doubt many know. Why do you all have to boast about your knowledge?
This explains a lot. When I'm exercising hard, after about ten minutes, I'll start time feel like I can't keep going. I'll usually take little micro breaks and slowly increase my intensity back to where I had it.
really great artwork and animation here, the colors were so vibrant and it really helped me absorb the information. They should show this at school.
Is this why there is stuff like water and Gatorade which have added "electrolytes"?
Kind of. When you exercise, you sweat. The sweat contains both electrolytes and water. If you drink just water the balace between this minerals (electrolytes) and water alters, which can cause many problems. That is why in long races you need salts, minerals or electrolytes (they refer to the same thing).
@@mikelzubieta6003 Sweat does not contain electrolytes

I think this gives a whole new meaning to “muscle mind connection” perhaps guys who get really big muscles have a better response to signals sent from the brain despite fatigue
Simply amazing

Our body functioning is so complex and it is smartly designed.
I wish there was a video like this for mental fatigue!
Towards the end of the video. It incorrectly shows muscles expanding when working. They contract.
When you extend your arm. Does the tricep contract or extend. I feel my triceps after I work out when i extend my arm so does it in that motion contract?
@@potatomanlp4812 Muscles are tighter when they contract. Like when people flex their arms and show off their biceps. Biceps are in a contracted state. So extending arms straight is contracting tricep.
Think about the scale of time at the level of brain signals to the chemical processes in the muscle. 🤯
I know right! I was moving my finger up and down while watching this video and thinking about how all this is happening in side my body in milliseconds
The illustrations are so good! 😍😍😍
This video is absolutely fantastic. Shows how absolutely essential micronutrients are!

A good explanation. Yet you forgot to include CTP(creatine triphosphate) a source of energy only found in muscle cells which gives a serious advantage to other tissue. TED is prized because of its inclusion of such important and interesting details. Keep up the good work.
It took us a whole semester to study this in highschool
One major contributor, discovered by Stanford University, is HEAT -- A student accidentally made the discovery when developing a solution for hypothermia... He created a device that used a vacuum to force open blood vessels in the skin and then heated the blood to raise the core body temperature. It worked remarkably well.
Later he decided to see if the process could also be applied to hyperthermia by cooling the person's blood. He decided to test it on school athletes suffering from heat exhaustion. Not only did the system work, but he also noticed a marked increase in overall athletic performance, reduced fatigue, and accelerated recovery.
This prompted additional study which revealed that heat caused ATP to break down in the cells, reducing energy production and causing lactic acid by-products. Simply cooling the blood at regular intervals greatly reduces these effects and increases performance.
The real truth is we don’t really understand how our muscles work, we have ideas and theories. This is the sliding filament theory from if I remember correctly 1954. There is still an untapped potential of muscle contraction and Bruce Lee was onto it using “overcoming isometrics”
Your muscles have enough power to rip themselves off the bone, the brain won’t allow it unless you can tap into the nervous system usually by a serious emergency the release of adrenaline helps. However I believe certain individuals can unlock most of the potential in a muscle at will through meditation and over coming isometrics. I have witnessed this myself in children and it’s quite frightening to be honest. I’d estimate that Bruce Lee himself got to about 85% potential
Very interesting!

How does the heart never get tired or build up lactic acid
It is a special muscle that has evolved for its function, like most things in our body. Whereas muscles in our arms, legs, etc. are skeletal, the heart is made of a different type of muscle (cardiac muscle).
Because it has passion
Oh the heart will get tired, it only takes, let's say 80 years
@@qresind its more due to degredation
@@qresind our body gets tired as our brain does - if that were the case everyone over the age of 80 would die, yet some live 20 even 30 years after this point.
Funny, I just did some biceps and youtube suggested this video! And I'm glad I've watched. Great video - funny and knowledgeable!
Lactic acid does not cause the muscle to fatigue neither, burn. Please check that one out for more accurate information! Hydrogen ions is the reasons why muscles burn because PH drops, lactate comes and pick up these ions to help buffer it from the muscle (actually it is helping you)
This is more complex that I thought but it made it even more interesting
One of the best illustrations! Keep up the good work guys! 🔥💯🤟🏻
I have trained my self so well to move fast in water if I ever get trapped too the point that I move fast enough that I can't push myself above water level making it so I do get trapped under water I can escape fast but I will drown
what about smooth muscles? why don't they get tired?
If I remember correctly from my Biology class, they do not. Unfortunately, this is the limit of my knowledge :|
They are on the inside of organs they do much but connect the tissue
Beautifull animation. Very organic. It fits in the theme perfectly
My brain muscles have certainly gone stronger after watching this.
Awesome explanation
So if im trying to improve my middle distance "1.5mi" run time, as a fairly conditioned athlete and the primary source of fatigue seems to be my legs burning and performing slower would that be from a lack of ATP? What would be the best strategy to improve fatigue resistance?
Did you not watch the video ? In the video it is stated that. "most of the time
2:34
even heavily fatigued muscles still have not depleted this energy source."
yeah. try to slow down for a bit. also you can try using 'creatine'. it increases atp in muscles.
Idk, try sleep schedules better. That's why
my personal conclusion from this video is that you should increase your ATP stores so that you fatigue less/recover from fatigue faster. As ATP is generally made up of Potassium, Sodium and Calcium (as stated in the video) find nutrition that is high in these. For example, milk is high in calcium, bananas are high in potassium, and sodium will be found in salt as it's Sodium Chloride. It's pretty easy to find more options just using google. Having bigger stores of the nutrients you muscles needs essentially gives your body more 'energy', should allow you to run further, tire out you muscles more, and allow for greater repair & growth so you can do even better next time. Side note: cardio needs alot of carbohydrates to use starch as a form of energy also, so try to eat a large meal of rice or pasta roughly 4-12hours beforehand aswell. Good luck dude.
These answers are simply very wrong haha. You won't lack ATP after 1,5 miles. The reason your legs will be burning is because of lactic acid. Lactate is produced when the muscles are not getting enough oxygen. You want to improve your aerobic endurance. two high intensity workouts + one long slow run is a good fundament for doing that.

I learnt a lot from this video. Thankyou
Key point: There are ions in and around muscles cells (K+, Na+. Ca2+). THese ions are necessary for muscle contraction. They can be depleted after repeated muscle use. (ion depletion @3:40).
- If you exercise regularly, less signals need to be sent from the brain to the muscle cell to contract your muscle. Thus there is slower depletion of the ions. @3:30.
@00:35 Reasons for muscle fatigue
1) lactic acid
2) running out of energy? (what does that means precisely?)
3) muscle's ability to respond to signals from the brain
muscle contraction:
- THere is a balance of Na+ ions outside the muscle cell, and K+ ions inside the muscle cell (@2:09)
- Due to nerve signals via motor neurons, these charged particles exchange Na and K
Action potential 1:35
- is an electrical signal spreading through the muscle cell.
- muscle cell releases calcium Ca
- Ca causes proteins to lock together, causing muscle contraction
@2:00 ATP
- is a form of energy
- is stored in muscle cells
- it is used by muscle cell to contract. It can get used up.
@2:50
- there need to be enough Na+, K+ and Ca2+ ions near the muscle cell to continue muscle contraction.
- these ions are used up during muscle contraction, but also repleneshed to some degree.
- action potential? @3:05
But how do ions deplete around muscle cell membrane if they flow in and out?
