Building Muscle Vs Building Strength What’s the Difference?
Video taken from the channel: PictureFit
Motor units are a big part of that adaptation. When you first start strength training, your brain responds by recruiting more and more motor units every time you contract a muscle. As you continue working out, you’re able to generate more force and your motor units fire at a more rapid pace.
This makes your movements faster and more efficient.Thus, the results of Milner-Brown, Stein, and Lee (1975) suggest an effect of strength training on supraspinal mechanisms that are responsible for the recruitment of motor units, possibly by an enhancement of the efficacy of synapses on motoneurons from supraspinal sources. These original findings have been supported by more recent studies.
However, strength training increases the length of time that a motor unit can stay activated without becoming tired or overworked. Therefore, neuromuscular adaptations enhance muscular endurance, or your ability for muscle action over time. For example, enhanced motor-unit endurance enables you to perform a greater amount of pushups or pullups in succession.Motor units act as connections for our muscles and the nervous system that operates them.
Motor unit recruitment relies on a process oforderly recruitment according to the size principle. This has important implications for strength training.It has been demonstrated, however, that training can increase both the rate of torque development and the discharge rate of motor units.
Furthermore, both strength training and practice of a force-matching task can evoke adaptations in the discharge characteristics of motor units.firing rates of the motor unit types upon changes from a physically inactive life to endurance or strength training. The muscle fibers react to prolonged exercise by adaptation to a higher level of performance.
A matter of discussion is the prerequisites for a transformation between the basic muscle fiber types, slow.Muscle Activation and Strength Training Periodization of training is based on the principle that different loads (e.g., light, moderate, or heavy) or power requirements recruit different types and numbers of motor units. Recruitment order is important from a practical standpoint for several reasons.This review covers underlying physiological characteristics and training considerations that may affect muscular strength including improving maximal force expression and time-limited force expression. Strength is underpinned by a combination of morphological and neural factors including muscle cross-sectional area and architecture, musculotendinous stiffness, motor unit recruitment, rate.
A motor unit is a special unit within your muscles that innervates, or activates, a number of muscle fibers. Fibers contract, generating force in response to stress, so the motor unit signals the fibers to contract, which is where your muscular power comes from.As a motor act proceeds from little to maximum strength, motor units with precise characteristics are progressively recruited in a logical order. First are the smallest tonic motor units, followed by larger tonic units, and finally by the largest tonic units.
Motor unit recruitment is (a big part of) the way in which the central nervous system (CNS) controls force production in muscles. There are many motor units for each muscle, and each motor unit.It should be noted that the Maximal Effort method is the superior method for recruiting the maximum number of motor units and for developing maximal strength.
However, it is very easy to abuse the ME method and cause a de-training effect.What is fact is that strength training is needed to provide a training stimulus to maintain the Type IIb motor units. Another fact is that a decrease in physical activity causes the muscle fibers in Type IIb motor units to atrophy (lose size and force-producing capability) more quickly than the fibers in Type I and Type IIa motor units.
Alterations in the nervous system firing pattern can occur as a result of training. Motor unit recruitment and the firing pattern to muscle can change with training also. The improvement in the.
During a muscle contraction, the central nervous system controls the production of increased muscle force by either increasing motor unit firing rates and/or the recruitment of.

What is Custokebon Secrets and how does it work? I hear a lot of people burn their weight with this popular fat burn methods.
I am taking a physiology course online and I find having videos like this is extremely helpful! This video is very well explained and also uses good visual cues. It is also very helpful b/c it uses the same terminology as the course
I never understood why anyone would want to train for “strength”. Isnt the entire point of working out/exercising to be, feel, and mostly LOOK better!? ( unless your training for strong man contest er somthing? Clearly study after study for over 40 years has shown that hypertrophy is best for muscle definition and mass. Allowing the muscles to be and look bigger. Whereas “strength training” is clearly to make you stronger. Yet for some reason the mass majority of lifters do split training for strength gains. I mean… are we all walking around with a fridge on our backs? Still dont get it… ” I can bench more than you bro” “sure but your bitch is staring at ME when my shirt is off.” Its almost like who can drink faster? Usually its the guy who is shitfaced in his buddy’s toilet. Yet the guy who drank less, over longer period of time allowing himself to enjoy the night with Mr. Shitface’s dream girl.. just food for thought…
Does Custokebon Secrets really work? I notice a lot of people keep on speaking about Custokebon Secrets. But Im not sure if it’s good enough to lost a lot of fat.
When you’re watching to study for a biomed exam but he’s basically describing your current ongoing symptoms. That sad “Aha” moment.
How effective is Custokebon Secrets? We’ve noticed many awesome things about this popular weight loss diet plan.
Since finding this channel I’ve discovered jujimufu and I just learned his academic background is in biotech. I’d love to watch you both talk about science and workout.
Too good explanation..short n to the point..��made it v clear..thank you
Hey! Big fan. Do you have any videos on how to become more durable? Not just last longer in a fight or physical activity but also how to be more durable to damage. For example if you’re a fighter like a boxer, how would condition you’re body to take more hits. How can you make your body more tough and durable like Captain America for example.
So the amount of electricity flowing through the nerve determines how much the muscle will contract?
I notice lots of people keep on talking about Custokebon Secrets. But I’m not sure if it’s good. Have you ever try this popular weight loss diet plan?
I started lifting when I was 15 and made huge amounts of progress when it came to muscle size but strength was lacking up until I was 17 and started doing heavy sets with high reps. It seems to me that if you build endurance up when doing weight training is coincides with strength. I have a buddy who I workout with from time to time that does low reps and moderate weight and he’s strong but i do heavy weight with as many reps as I can do before failure.
ok, so. I have a question concerning this and my current training. In Tai Chi we stand in the wuji stance which is a gravity isometric exercise that focuses almost exclusively on the quadriceps. I have enough medical knowledge to already know what is going on in my nervous system and musculature but what I want to know is…. Is there an amount of time that would be ideal for this type of exercise, I do it for 20 minutes a day, feel free to check my channel, I do it on camera. Some Tai Chi practitioners claim to do it for 4 hours a day but i think that is a bit too obsessive. Thank you. I also wanted to know if adding weights will have any added benefits and if so, how?
Another fact is 90% of people in the gym are just building muscles just to be in a good shape no real strenght.
Is it possible to produce the same torque/force but less muscular activity (less EMG activity)? If so, why?
Pure strength is optimal because it puts you at your strongest while also giving you the smallest hurt box possible
One way strength training helped me was when I couldn’t do pull ups at all even though my muscles were strong enough to do a pull up I decided to do some strength training and now i can do repetitive 10 pull ups at a time.
Great info as always! Thanks for all of your videos! ��������
Wait.. so it’s better to do strength workouts then grow muscles!?
You should write a book on exercise. I would definitely find something like that to be interesting��
if you wanna look good go for muscle gain, if you wanna get strong go for strength training, if you wanna be a fighter practice kicking and punching effectively with good technique.
This is EXACTLY why Hyperarch works.For instance when you make you foot stiff and lock you ankles and attempt to do a squat.Your body just like the Bioneer stated will not allow the need to do ass to grass and not only get better results from getting ass to grass people do,but be more effecient in the long all than those that do it.I can bet anyone in here 50 bucks or more The Bioneer has visible tendons on BOTH of his feet.What that simply means is Bioneer at a subconscience/alert state meaning EVERYTHING he does his brain doesnt forget to make his FEET store tension.The body fascia is STRONG in this one for sure.
I see all that all that coffee is paying off with this high quality content�� ☕️
Did you match your t-shirt with the background on purpose?����
go vegan you’ll get cut. it’s science based low inflammation
I have no idea what he is saying so basically people like Arnold and Sylvester are weak?
great use of using digital diagrams and illustrations, and your cadence in speech was good.
So I’m guessing saitama workout for strength? Rip muscle dream
I dont like those animated videos in between ��❗�� remove them just talk only and show how to do it
Stamina allows you to stay alive. The amount of reps you do when you have to push and keep your opponents away from your QB for the WHOLE GAME: Tell me, what is the reason?
Is it building Strength that keeps your O-Line strong or the amount of reps that keeps your O-Line strong?
4:26 I think I know what he trained so that only his left hand be strong
A resting nerve sits at -70 millivolts
Anything under -55 mlVLs is considered by the nerve a false alarm
In short:
For shape/size gain, increasing volume is more important, which is the multiple of sets times reps times intensity(weight). 3-5 sets of 8-12 reps is the sweet spot.
For strength gain, lower reps are more important (1-5 reps per set with 85-100% 1rm)
I’m thinking about doing small quiz/questionnaire based on each video for prizes. What do you guys think?
Remember guys, Bruce Lee was not the biggest but he was easily able to make a really heavy punching bag fall from the roof.
Nah I just want to get stronger no real interest in increasing my mass anywhere more than I need too.
The way you explain the information is just brilliant, i learned legit 20x faster and better than i ever did in biology class, what they are trying to hammer inside of us in months, you do so well in one video!
Keep up the good work, love the content! Finally a channel where i don’t feel the host is learning in the same time as i’m watching.
Leonardo and Nigtwing in the same channel. My dream is become real!!!:D Thanks maannn!!!
So like every anime character only increases strength bc they are skinny as freak.
Theres a really cool experiment that you can do to demonstrate rate coding by electrically stimulating the radial nerve at increasing frequencies. At a high frequency you physically can’t open your hand!
Yo i been subbed for a few years ur one of the most intellegent personalities on youtube i love hiw you go into such detail even giving training methods and tips you explain pros and cons seriously you need atleast 1million+ subs because all these ither channels out here spouting nonsense.
Anyone maximizing their time will build strength AND muscle. Without one there isn’t the other. You’ll hit a ceiling in either category if you don’t utilize both.
Here’s the link to join the Strength and Conditioning Study Group on Facebook: facebook.com/groups/2415992685342170
Ok…. I think a second or maybe third viewing is in order to let that all sink in ����
If we just look like a small fry but started kicking the bad guy wouldn’t dat be badass
I had a doubt!
How does one neuron decide how many neuromuscular junctions to activate?
And when you say that neuromuscular junctions are recruited, are they like created or something over the existing muscle fibre?
Sorry if it seems trivial, I was just mind blown as to how muscle bulk up. ��
Love your work. ��
Stop promoting the ‘perfect body.’ You’re part of the problem.
Hi there, I want to know if Custokebon Secrets, will really work for me? I notice lots of people keep on speaking about this popular fat burn secrets.
Question, if all the muscle fibers are being activated on one signal from the nervous system, how can only one type be recruited for specific jobs?
If my eyes cause my brain to recruit the correct about of motor units, what happens for a blind person?
How do they recruit the correct amount of motor units.
What role does muscle spindles have?
Hi
Great video. With the neural adaptations… Would these carry on after the 6-8 weeks with the additional support of the muscle hypertrophy as you are aiming to progress the exercise program?
Salutations! Anyone know the name of the exercise @ 9:19? Thanks.
I really dont know how the fuck people fall for this bullshit. Bro if you want muscle and strength just continue with progressive overload, especially if youre a natural training with less intensity but more volume isnt gonna do shit for you. This is how you work out and ik its like very complicated so bear with me, you first google how to do and what are the most important compound movements, next u go to the gym and u start doing those compound lifts with weights you can lift, you keep lifting that weight till it feels easy, after that u add more weight to the bar and guess what? Repeat till you hit a point in your training career where you cant go any further. Ik, super complicated shit. As for sets? 3 lol. Reps? Around 12 aka when the current weight feels easy aka when you should add more weight. There you go, now piss off and go lift instead of wasting your time with bullshit like this.
Great video! I was wondering if there’s any reason why you choose to do your bench press with open wide elbows?
Sir can you please make a video on Prisoner workout and Navy Seal / Military workout routine
A motor unit is the neuron and the muscle fibers it innervates.
People here want a fitness model or workout from you…. I say YOU have the capability of delivering a super human nutritional program. Incorporate tendon strengthening and additional overlooked science behind becoming superhuman. Include organ enhancement and central nervous training.
Hello, great video! But wouldn’t the hypertrophy start later in the process.. the way you’r drawing it now suggests that hypertrophy strat immediately after beginning with exercise, but this is just transient hypertrophy which fades away after several hours
.. it should start later!
My uncle isnt ripped, but he lifts 200lbs+ like it’s nothing
One gets you muscular, strong and attractive; other one fat, very strong and ugly.
Thanks!
The others on my club would always be pissed pf because I would do better than them without training half of what they do. Now they can understand me a little more
Love your channel man, hope you keep doing this stuff. Your videos are well researched, not douchey at all and just so well put together and interesting.
Best to you and your family from germany
Hey dude love your videos! I was wondering though if you have an opinion on deer antler velvet? I’ve heard conflicting things and don’t know what to believe. Have you ever tried it?
Did I miss something? Why wouldn’t you just want strength, rather than muscle?
I think Shaolin monks are the best example for not jacked strong people.
Hey did your second video ever upload? I find your videos easy to understand.
I have an exam tomorrow too.
I guess we only come here a day before the exam.
Hey The Bioneer, video suggestion about barefoot running and also bare knuckle boxing.
Does Custokebon Secrets really work? I see many people keep on speaking about Custokebon Secrets. But Im uncertain if it’s good enough to lost a lot of weight.
This is my new favorite, all across the board, self improvement, mental and physical development channel. I’m glad I stumbled across it. Thank you so much for all of this information. I will use it.
I’m an MMA fighter. My main style are Muay Thai, Dutch Kickboxing, and BJJ. I need to get as strong as I can possibly get without getting heavier so I don’t go up in weight classes (the guys in the next weight class up will probably eat me for breakfast).
Also, let me tell you. Weight cutting is pure hell.
Is it possible for the human body to duplicate the amounts of motor units
Very fluent delivery of muscle physiology basics.
The human body is the most complex machine in the universe.
words cannot espresso how good the quality of these videos are
it’s too brewtiful
if you didn’t have any espresso while editing, i bet you would’ve been depresso
ahaha, these puns are going to cause a latte problems if i don’t stop
if you have some, hit me with your best shot
Bro saludos desde venezuela soñe con este video y mientras lo veia tuve esa sensacion de “deja Vu” jajjajaj era una señal que me dio las respuestas a mks preguntas GRAN VIDEO
Can I get a link on the article exploring single set vs multiple sets for strength gains?
Thank you more content please!
About naufi Aguilar functional patterns and dr Jack kruse On 5g safety������
I do push ups 4 sets of 15
Lift 5 kilos weigths 4 sets of 15
Squats 4 sets of 20
And abs 4 sets of 20
What am i developing?
I feel like I train for hypertrophy but exclusively seek strength lol
The only thing I think I know about biomechanics is
Short arms=work
Longer arms=little more work
And I don’t even know if this is 100% correct so I’m sorry if I’m wrong
I’ve read that lighter weights can enguage your nervous system when they get heavy, which kinda makes sense. I can’t find the link, you’ll have to look it up or take my work for it.
I love your videos man, nobody else is doing it like this and so well. I want to one day see a collaboration between you and Frank Yang.
I hear lots of people keep on talking about Custokebon Secrets. But I’m uncertain if it is good. Have you ever tried using this popular fat burn secrets?
Me after watching this video:
If I lIfT a CaR oNcE i CaN bEcOmE sTrOnGeR tHaN 10 10kG dUmBeLl LiFtS
Thank you, I needed this more than anyone, because I have known the benefits of it, I could memorize stuffs so much very faster when I was a hyperactive kid, this is an answer to my prayer bro, I’m 19 now and fat.
Oh also i came across this thing called arachidonic acid? Its pills increases acid inflammation in in ur muscles it says its like steroids but its not and you will get really big you have to workout obviously if you take it n do nothing then nothing will happen for you what r youre thoughts on it?
That makes no sense. You can’t have one without the other. This is freaking retarded. Muscle is strength.
Isn’t Peak Contraction and Peak Tension basically Hypertrophy or I am wrong? Also, how do motor neurons work in Concentric, Eccentric, and Isometric muscle activity?
I was searching for this thanks I don’t want that bulk I just need strength. No show off
so this is how saitama got the strength of a god while still maintaining the body of a normal person..
I’m not sure if im correct, but I do both max volume and max intensity, so i train for both muscle and strength..i do curls at 10 reps at 90% of my max with the help of my other hand ����
Studying the CSCS and watching these videos is helping tremendously. Love what ya do!
@ 4:45… the “vagina”… “all the way down”…???? what the??? i thought this was about motor units and you are bringing up all the way down to the vagina???
Question do if you train for strength then train for size do you lose strength while training for size?
Just found your channel from Medlife crisis! Love it already:)
THAT ASSESSMENT MENTIONED @ 9:30 min INTO THE CLIP IS FAULTY…BEFORE I GET INTO FURTHER EXPLANATION, YOU MIGHT WANT TO READ UP ON THAT ISSUE RIGHT HERE: http://www.t-nation.com/training/secret-to-motor-unit-recruitment
Muscles directly Co relate to strength… Look at those guys from world strongest man competition… They weigh all above 170 kg or 375 pounds of muscles… Yes some of them have a little belly but most of their weight and size are from muscles
hey bioneer, and everyone here, i’d like to recommend a channel to you guys, about bodybuilding.
it’s called expanding universe innovations
i hope that you all watch the video and subscribe and preach about him if you like the video
you can watch the video expander by the day 1 right now, and base your opinions on that. it’s about tons of different variations of pullups, which is not seen in mainstream media, just like bioneer content
THANK YOU SO MUCH FOR THIS VIDEO ������������������������❤️❤️❤️ def subscribing
1. If a person is diagnosed with motor neuropathy does this refer to a lower motor neuron disorder? 2. Does motor neuropathy refer to the peripheral nervous system? Thanks
Hello! Thank you for this helpful video. By the way, I notice lots of people keep on talking about Custokebon Secrets (just search it on google), but I’m not sure if it is good. Have you thought about Custokebon Secrets? I have heard some extraordinary things about it and my mate lost crazy amounts of weight with it, but she refuses to tell me:(
What is the best way to lost crazy amounts of weight? I read many superb opinions on the internet about how exactly Custokebon Secrets can assist you lost crazy amounts of fat. Has any one tried this popular fat burn secrets?
Word Porn! Love your videos man going from one strength to another
How can I develope bigger motor units as a teenager, and how?
Is the size of the motor unit at all related to whether its a fast or slow twitch muscle?
Man, you can contribute a lot. Your presentation though, sucks! Please work on not being a machine gun mouth and try to keep your audience in mind. Not everyone will have the same attention span. I cannot separate as well what was the relevant and irrelevant from your blabber. My takeaway was that you should do ISOMETRICS to train your nervous system and Im not sure if I got that right. Eventually I might just unsub.
This video was great, helped me for my AP Biology midterms tomorrow! Thank you loads!!
Great to find hindi subtitles
But frankly speaking majority of med student in india don’t switch to hindi subtitles rather like English onces as INDIANS are OK with ENGLISH LANGUAGE
Guys. lost crazy amounts of weight does not need to be hard (I used to feel it did). I’m going to give you some advice right now. Look for a popular fat burn diet plan called Custokebon Secrets (just google it). Thanks to it I have lost tons of fat. I shouldn’t even be talking about it cause I don’t want a bunch of other guys out there running exactly the same game but whatever. I am just simply in a great mood right now so I will share the wealth haha.
This video has great information, but I’m confused about the best diet plan that I need to work with, only because I have never taken any. Anybody tried using the Custokebon Secrets? I’ve noticed several folks talk about incredible things about Custokebon Secrets.
Definitely one of my favourite fitness youtubers, straight to the point yet detailed enough to have substance, you deserve so many more subs!
This has gotta be my favorite channel on YouTube. These videos are so informative and helpful. Keep experimenting!
If you want to shed pounds, you should search Custokebon Secrets on google. They’ll help you get the shape you deserve.
Hey Adam, just wondering if you are into the AC games and if so would you ever consider making a video with that sort of theme. and by the way if you haven’t played them all you need to play is AC 2 through Revelations, brotherhood is the best one. Haha
This channel will eventually get the 1 million+ subs it deserves
How to build muscle:
train type IIa muscle fibres
do 10-20 reps and so many sets as its healthy for you
How to build strength:
train type Ia, IIa, IIb muscle fibres
-do isometrics
3 seconds for 3 times, 3 sets
How to develope speed:
train type IIb muscle fibres
leave the training when you feel energytic
train everyday
• lift both heavy and light weights
heavy weights
3 reps, (individual number of sets), maximal mental effort
light weights (the weight which you can lift, and not seeing any difference in speed of the contraction with or without the weight)
5 reps, (individual number of sets), maximal mental effort and speed
It would be a waste for you not to get rid of fat while other typical people are able to shed weight very easily with Custokebon Secrets (search on google).
Basically you want to get more strength? Use heavier weights… Simple
This was an amazing video. I will be watching this over and over to try and digest all the information you dropped here. This was so densely packed with quality and useful knowledge. Thank You.
fucking top video mate. im training to be a personal trainer and the training modules arent very clear on this subject, so for the assement i’ve spent about an hour searching for a descriptive source/ video. thanks heaps
Well, I want to build Muscles and build Strength
If your muscular, but not as strong as you look then it’s a waste that you only build muscles instead of lifting heavy
Building both Muscles ands Strength makes you a classic strong guy, and there’s three things I want to achieve when working out:
1. Bulking up
2. Staying Healthy
3. Being Strong
Im girl and i wanna get stronger not to get crushed like an ant again.
when u increase the number of muscle cell, does that mean u form new motor units that attach to the new muscle cell?
Excellent content.. been studying for a year now.. and I don’t know honestly why personal trainers need to study this level of complicated anatomy?
Can u plz explain whats the basic difference between pyramidal and extra pyramidal tracts?
Hey Bioneer! I found an incredible article for you that works as a great motivation supplement for your batman vdeos> https://www.quora.com/How-do-I-become-someone-like-Bruce-Wayne its pretty damn good
Your videos are really helping me learning fitness. I regularly watch your channel.
have my exam tomorrow found your series invaluable thank you x
