Muscle Hypertrophy Explained (What Makes Muscle Grow)
Vložit
- čas přidán 3. 02. 2023
- To gain muscle through weight lifting, you must have both metabolic fatigue and mechanical damage. When you lift heavy, the contractile proteins in your muscles must generate enough force to overcome the weight's resistance. This in turn can cause structural damage to the muscle. Mechanical damage to muscle proteins activates the body's repair response, muscle size increases as a result of the damaged protein fibers. The ATP, an energy component that supports the contraction of your muscles, is used up by the muscle fibers, which results in metabolic fatigue. They are unable to continue fueling muscle contractions or can no longer lift the weight effectively, this can also result in muscle growth. Gaining muscle hypertrophy requires both metabolic fatigue and mechanical damage. #Shorts #muscle #workout #hypertrophy

What’s cool about muscle memory is that if you were jacked once, and stopped working out for some reason, lost a ton of muscle. You’re able to build it back pretty quickly, or at least faster than most people.

@@smartwhip. it's basically saving your muscle blueprints in order to rebuild them more quickly
@@smartwhip. Some muscle cells retain two nucleus instead of one when one loses muscle mass. When they start working out again, the two nucleus in the muscle cells allows faster generation of cells by splitting apart instead of making one from the beginning.

Feeling sore the next day is a good sign🔥🔥🔥🔥
Not necessarily
@@lukewiggins303 Could you explain please?
@ismaeelsaqib9498 As a newer lifter getting sore can be a good sign that your training hard and hitting the correct nuscle group, but as you advance in the lifting game you shouldnt be getting sore after you workouts especially if you work it regularly. If you workout 4-6 days a week and you get sore after your workouts its indicative of poor recovery/overtraining. Once your body becomes uccustomed to training, soreness becomes a bad thing. Always listen to your body. Pain means something is wrong.
Soreness is not relative to success. Many people as they get their bodies used to lifting stop getting sore and feel nothing the next day.
This is the biggest issue with people that think they can go right back to working the same muscle group right away because it doesn’t feel sore, when they still need significant rest time for the muscle to repair and then build more muscle on top.
Some advanced lifters never feel sore.

Make sure you have your rest days so your muscles can grow💯
Two sets to failure with good form, mind-muscle connection, proper rate, etc. Is my new favorite thing.
Muscles do not grow from the damage. They grow through mechanical tension, there are "sensors" in your muscles that are able to tell when they are under stress. Damage to your muscles is bound to happen when you workout but correlation doesn't equal causation.
In simple English please?!...how are we supposed to train?
@@liveuser8527 There are things in your muscles that sense when your muscles are being worked hard. These sensors tell the rest of your body to make your muscles stronger so you can lift heavier things. When you work your muscles hard they are going to get damaged from the stress. But just because they get damaged from working out doesn't mean that is what makes your muscles get bigger. You're just supposed to train hard and near or at muscular failure, put emphasis on form rather than weight and do everything in between 6-12 reps. Make sure to use different variations of the same movement because your muscles are made up of different parts and small changes to your movement can activate different parts of the same muscle. For example, you can use different attachments on the rowing machine, like overhand grip, underhand grip and single arm rows. Each one will put use slightly different muscles making sure that you won't be overdeveloped in some areas and underdeveloped in others.
@@Utopian1234 so 6-12 reps?..ho many sets?
@@liveuser8527 It honestly depends on the muscle but you'll be good as long as you stay in between 12-18 reps per muscle group. And a few examples of a muscle group would be your chest, quads and biceps. Each muscle group is made up of different parts called heads that's why they're muscle groups. What you should do is this thing called a split, there are many different types of splits but what it is is a weekly plan of what muscles you're going to hit. An example of one would be chest and back on Monday, Legs on Tuesday, arms on Wednesday rest on Thursday, Legs again on Friday, then your whole upper body on Saturday, and rest on Sunday. However you don't need to do that. There are many different types of splits. One called an Arnold split which is the example i gave, there's also push, pull legs. Which is chest and triceps, then back and biceps, and then legs. You can look into it further and find a split that works for you or if you really want you can make your own. But if you want to just search up "Different types of gym splits" on Google and you can choose whichever one you want. If you have any more questions just let me know. I wish you the best of luck.
@@liveuser8527 One last thing, rest is important make sure you take at least 2 days a week. As a natural lifter who doesn't take steroids your body needs to time to recover from the stress of working out. Also NEVER take steroids or SARMs. I don't know if you're considering it but it is not worth it.

@@avintheconqueror increased muscle is literally a physiological adaptation to increasing mechanical stress on the body. It's not defending against anything, it's becoming more efficient
Props to this man for taking off his skin and demonstrating scientific information 👍👍
I think it's well-established that muscle damage isn't a significant driver of hypertrophy. The mechanical tension and motor neuron activation prompts tissue growth as an adaptation. Tissue repair only consumes energy and protein, hindering further anabolism if anything.
Was looking for exactly this! So much "bro science" being peddled as actual information.
“No pain no gain”
Mechanical tension, and you don’t need to overcome a weight. You need to produce force. That can be done with a static hold. Or even a negative.
People sleeping on that eccentric muscle stress. 🔥 💪
Good point and is the reason gymnast are jacked
He siad "when you lift heavy they need to overcome the weight."...
Maybe negative, but a static hold doesn't increase muscle, it makes your body use the whole muscle if it doesn't already.

@@drwealz he means 99% content of your channel.
Except that studies indicate that what's actually needed is prolonged muscle tension that stimulates the nerves in muscles. The damage doesn't impact the process, it's a byproduct. Muscle hypertrophy is a great channel for such info.

Wouldnt work cause its not mechanical damage it’s mechanical tension what stimulates hypertrophy
@@tasbirmiah5247 no it’s not. The damage caused in the muscle is a side effect of the tension placed on it. The damage doesn’t cause a hypertrophic response only the tension
@@tasbirmiah5247 it’s not because of the damage I’ll tell u that much
@@tasbirmiah5247 me not answering the question doesn’t disprove the fact that muscle damage is not the main driver of muscle growth. I don’t care how tension makes muscles grow I just care if it does make them grow
What doesn't kill you makes you stronger.
The only example I have heard of damage actually being a good thing. Bring on the damage!
The thing people forget is that to build muscle you obtain a very minor amount of muscle damage if your muscles actually hurt a lot you're not building muscle you're just screwing yourself up.

Suffering from success
The mechanical damage is more relevant to (slowly) increasing the maximum length of sarcomeres (in other words lengthening you muscle, unfortunately data is missing on rather if this eventually results in slightly shorter tendons down the line or not).
structural damage does upregulate protein synthesis, though this is almost entirely just repairing the damaged muscle, especially in the first few hours. (and of course structural damage does not usually happen without metabolic fatigue.)
In regards to increasing cross sectional area specifically, metabolic fatigue is the primary factor and mechanical damage does not seem to provide any significant improvement in thia regard (again, it's more useful for growth by means of lengthening, which is much slower than increasing CSA).
Also the metabolic fatigue does not necessarily have to all be in the same moment, spreading the fatigue accross the day/week is effective too- relatedly, data is missing to see if lactic acid buildup improves growth or not, but given that high levels of lactic acid are a bit toxic, it might actually be more reasonable to do the same amount of work accross more sets (but I don't think it's too detrimental to go to failure given that most people who do this make good results, and it can possibly save time).
Source?
@@chucknorris6256 source 😂😂 every fukin study says this
@@chucknorris6256 I could try to find it again, but it's free and publicly available information, so it shouldn't be tooooo hard to find yourself (and I'm currently bussy with other information hunting)- but important things to remember are that increased protein synthesis in the (contractile) cells of a muscle does not always coincide with increase in CSA (it can be merely just to repair the muscle),
and secondly that muscle growth IS NOT the same as increase in CSA, the lengthening of muscles like what happens to kids as they grow taller is also a form of muscle growth, sometimes thw wording is different from study to study, so make sure to pay attention to the details and any definitions they give (and any additional definitions necessary to understand those definitions).
Also to put part of what I said into simple terms basically the more a muscle is used, the thicker it grows (heavier weights, higher frequency, yadda yadda basically increase the muscle's calorie expenditure).
Translation: tom platz knows what he's doing
I like how the body is like “damn, we fucked that up, better get bigger”
honestly just glad this one actually shows muscle hypertrophy
ATP depletion stimulating muscle growth is not clearly explained nor makes common sense, but muscle fiber damages cause muscle growth making sense which is similar to hypertrophied joints after recovery from injuries.
It all comes back to mechanical tension at the end of the day.
Depending on the load and how the set is performed, one of two things will happen.
a) ATP depletion will lead to prevent muscle contraction in lower threshold muscle units first, requiring higher threshold muscle units to be recruited to maintain the same force. As these units progressively fatigue, the remaining ones will be required to express their maximum force thereby developing mechanical tension in those fibers leading to hypertrophy.
b) Higher threshold motor units will fatigue first due to ATP depletion. Same process will take place as motor units progressively shut off from the top down, until lower threshold units are expressing their max force.
It's not about damaging your muscles specifically.
It's about applying more resistance to them as time goes on or in simple terms progressive overload.
To make your body grow you have to work at your maximum intensity until you get to the point where your muscles can no longer succeed in performing the exercise and you achieve failure.
When that happens your body will trigger growth mechanisms in order to be prepared for that level of intensity in the next workout, so in the next time you workout with the same exercise, your body will be prepared for 225 for 6 on bench press but it won't be prepared for the 7th rep and when you go for that 7th rep you'll trigger the griwth mechanisms again cause your body understands: s**t I have to get ready for that level of difficulty again.
Long term progression is the key
These videos are made by robots. No humans involved. They don't seem entirely factual.
Progressive overload is just a training principle.
What drives hypertrophy though is mechanical tension and not mechanical damage as said in this video.
And it is still unclear whether or not metabolic stress is anabolic
*mechanical tension (is the sole driver of muscle hypertrophy, not muscle damage & metabolic fatigue)
Without optimal hormone balance, nothing will ever work!

No, muscle damage doesn’t cause hypertrophy, only mechanical tension
They go hand and hand !
Mechanical Tension is happening when you stretch the muscle fibres and you can achieve that only by lifting heavy and doing the correct form of the exercice .....
So lifting heavy with low reps is a must to build muscle you want to call it muscle damage or mechanical tension it's up to you !

@@user-jh2uw1zl6eo you are wrong the person is right, muscle damage doesn’t cause muscle growth. Why are the legs of soccer players/basketball players smaller than the legs of bodybuilders?

Muscle damage can be low and you can still gain muscle regardless.

I'm sure I've watched this video every 3 months and each time the thumbnail makes me wanna watch it
Weird question, and potentially dangerous, but bear with me: Could we cause muscle growth by working out with relatively smaller weight, but without warming up, which also causes muscle damage? The capability of working with a larger weight grows when warmed up. It's really a tangent thought. The suggestion then would be to do a set with medium weight cold. I wouldn't be able to do it myself, I feel my tissues are super cranky in the beginning, and need that oil-up from the warmup.
The body wont respond with the same results as lifting moderately heavy to heavy weights. Light weight high reps is more optimal for muscle and mechanical conditioning rather than muscle breakdown and hypertrophy. A decent analogy is an olympic 10k Meter runner will never be a bodybuilder😂
You can get gain with body weight... What causes muscle growth??
1. Metabolic stress aka Stimulation and volume of work
2. Mechanical tension aka the movement and the range of motion
3. Nutrition aka get good...ehh nutrition.
4. Rest aka allow your muscles to repair themselves
In theory and in practice you can grow your muscles with just calisthenics. What would be different?? The volume, the technique and the method used. Certainly with lower weight, you either increase the contraction time, the tempo, the repetitions, the angle or the difficulty...for instance, instead of doing normal push ups, you do one armed push ups...etc.
You might skip warming up, but you will reduce the metabolic efficiency, you will waste energy and might increase the response time of your nervous system, making you more probable to suffer an injury on a bad movement or to crush your joints.
Cold showers are good, but not after the work out, it is proven that reducing the swelling/pump after the training session reduces the muscle grow and the recovery, some authors might suggest even a 10%. Get cold showers the next day or in your rest days, not immediately after the work out.
@@mcmerry2846 Cold showers…that’s just what people do who want life to be miserable.

@@Granite_5.2. Agree, people grow better with lighter weights because it’s easier to control the weights with the muscle you are trying to train.
So basically the muscle adapts to survival. If you can’t lift 30 pounds and you struggle to do so but continue to try the muscle breaks down and grows bigger so you can lift it. It’s amazing how the body works

No pain no gain✅
this make sense as md student. basically the body is stressed to a point where it wasn't expecting so it deploys new set tissue that can withstand the next stressor to protect it self. which is why you should put more stress than it is expecting making the body produce stronger tissue that can withstand the stress.

@RAYHAN REHEMA PUTRA there's many nations that don't speak English the more languages you speak the more people you can reach
can you talk about the biological differences to myofibrillar hypertrophy and sarcoplasmic hypertrophy??
The sarcoplasm is the muscle cell wall. Myofibrils are the bundles of little fibers of actin and myosin which attach to each other to allow for muscle contraction.
In other words, at the top layer is the sarcomere, then there are the myofibrils, and within those are the microfilaments which are things like actin and myosin as well as the lines and Z disks etc.
After a workout, the microfilaments will be damaged and so will recruit satellite cells to increase their density and size. This in turn causes the myofibrils to grow, which requires the sarcomere to grow, otherwise there might be damage to it.
Myofibrillar hypertrophy occurs when the tubes that are bundled together to make up your muscle fiber increase in density & number, & sarcoplasmic hypertrophy occurs when more intra cellular fluid is stored in your muscles.
@@dariusgoatland10 not number, just density and size
@@BrendonCap No, the number of myofibrils definitely increases. The number of myofibrils per muscle fiber will increase 40x from infancy to adulthood regardless of training. You actually think you have a fixed amount of myofibrils at birth? You think your grandmother had the same number of myofibrils on her death bed as she did when she was 22?
The number is variable, & is regulated by the environmental demands imposed on an organism. Myofibrillar hypertrophy occurs when there’s an increase in the volume of myofibrils within a muscle fiber as well as an increase in the density of each individual myofibril. Both result in an increase in the size of a muscle fiber, & thus an increase in the size of a fascicle, & thus an increase in a muscle’s size.
@@BrendonCap Number of myofribrils won't change but number of sarcomeres in parallel does, which is the only thing that matters at the end of the day when it comes to muscle CSA and force generating potential.
