I have a question related to the topic of the 2 muscle fibres and how they act, but I feel I must briefly describe wat I do for a living to explain my question. I work at a lumber mill in Ontario Canada. I work in the large planer as (primarily) a piler. Wat a piler does is pile lumber into lifts. In a planer, lumber will be brought in to be dressed down and/or graded out and the lumber that is being ordered is to be piled into the requested lifts. Most of my piling is done off a set of 5 chains that r best described as each being a pair of hockey skate blades for each link. This does cause a lot more friction when piling lumber then the chains found in other work areas that have a metal plate in top of them. In the planer I work in 90% of wat we do is red and white pine. The range of size of lumber we process in my planer is from 1X2X6 to 12X12X24. Luckily the largest lumber I’ve ever had the pleasure of piling sence I started 3 years ago was 10X10X16 red pine that was soaken wet and had 2” of ice. I’ve estimated each of those timbers weight 600-700lbs each. So now onto the question: Both me and my relatives as well as all of my experienced coworkers believe that “u r useless if u can’t do both pile heavy lumber and do it consistently all day long. We don’t care how much u can lift if it means u r exhausted for the rest of the day after merely 10 mins of work. We don’t care how fast or how energetic u r if u can’t pile heavy lumber.”. I am able to pile some quite heavy ass lumber like it’s nothing and do it all day non stop. So How do I know wat kind of muscle fibres I have and a guesstimate of wat ratio of slow:fast twitch muscle fibres I got in my arms? And also how is it that I find working out in a gym (which I did for 1 semester in highschool) fucking useless and actually detrimental and a waste of time? After I did that 1 semester of fitness class I’ve been weaker and less fit ever sence. I started to feel and become weaker imo after 2 months of it. Ever sence then I’ve been slower and have had less stamina than I did in my teen years. Btw I’m 21yo, 5’10”, and weight 175lbs. And I’d guess my legs have about twice the amount of muscle as my arms do. I’m pretty “normal” looking in size. Not much bigger than the guy in the vid. I hope some1 reads this and can answer my questions.

@@baileydombroskie3046 if you workout consistently, eat properly, and sleep enough you will get stronger. thats just a simple fact, but it takes a lot of time and commitment. if you have more fast twitch muscle fibers it doesnt mean you cant gain slow twitch, if you want to just do good at ur job then simply doing ur job consistently will make you better. but if you want to gain muscle or gain endurance just go for it and do it. your job performance has to do with lots of things, your skill, technique, experience, will, strength cardio vascular endurance and much more, so dont be too focused on your job performance to judge your workout abilities. and i doubt there is a correlation between you working out and the decrease in strength, working out isnt magic, but you have to do it right, and you cannot simply expect to workout a lil, not know what you are doing and become larry wheels

@@danielschultz6470 I c. When I did fitness class in highschool for that 1 semester I found after like 2 weeks of doing only the weight related exercises not only was I getting needlessly weaker by 30% over that time I also found my muscles that I worked in a day to be useless or unreasonably tired and hurting for about 1-2 days afterwards of which I had never experienced b4 or after and caused me to be unable to help my dad at his farm. So after those 2 weeks I decided to do cardio on the bike, olyptical (I think that’s wat it was called), and the treadmill and only do 1 day every 4 weeks of the weight related exercises in 1 class. When me and my friend who both took the same fitness class wud do the cardio together we wud bring in our school chrome books and my iPad and his tablet and talk and play games together while we casually did cardio. According to the machines I was burning on average of 350 cals on the bikes, 500 cals on the Olympical, and 900 cals on the treadmill. My record in 1 hour of cardio was done on the treadmill which was 1,100 cals. And I wasn’t even trying THAT hard compared to if I did as best I cud. And I still did that session while talking and playing games with my friend. B4 i decided to mostly focus on cardio my max weight I cud leg press was 325lbs and at 12 reps. At 300lbs for 22 reps. When it was nearing exams, so 4-4.5 months later I tried the leg press 1 last time in front of the teacher and 2 other students to show any and all of my progress over that time. My max weight was now 375lbs and with that weight I was able to very casually do over 100 reps and the only reason I stopped around 102 was bcuz I frankly was getting bored and my teacher and fellow students were all (15++ students btw) watching in awe and shock and no1 cud understand wtf I just did in front of them. After I stopped my teacher walked away saying “bailey, idk wat the fuck u just did and how it even happened but my god I got no answer.” This is a paraphrase btw, my memory is not good enuf to remember his exact words. According to all the research material I cud find online as well as wat the teacher knew, it was said to be impossible to manage more then 8 reps at max weight, 12 reps at 75% weight, and 20 reps at 60% weight. I shud also mention that I’ve been working sence I was 3yo. It started out as just simply raking the hay up behind the bailer with my grandma as my dad was bailing. But as time went on I helped out more, more, and more. By 8yo I was around 70-80lbs and was carrying cedar posts in the bush up hills to the fence line with my dad. Those posts weighted anywhere from 40-100lbs each, at least the 1s I cud carry not drag. And last year out of curiosity and feeling like it I found that when I was carrying pails of water from the well to the the barn where the bull was locked up to water him, I realized that the approximately 60lbs per pail of water (include the steel pail) was no match for the power each of my fingers possess. I casually showed off to my dad’s female friend how I cud carrying 2 pails of water that 100’ ish while only using my pinkie fingers and only holding the pails with just the last joint of the fingers. I am able to do it with all my fingers like this with no difficulty at all. But I’m not concerned about my performance at work as no1 can keep up to me and no1 can do as good of a job as me simultaneously. I was simply wondering wat kinds of muscle fibres I likely have and how much is the estimated ratio between the 2. Bcuz I can work for 3 hours nonstop at full speed does that mean my muscles r primarily fast twitch? It’s just confusing when I apply this knowledge to myself bcuz 99% of wat I can do I can do for a long time and there is no weakness of not being able to do 100% for a long time like the idea of fast twitch fibres suggests. It’s like my muscles r choosing to have the benefits of both muscle fibres without the downsides of either.

Exercising can be hard sometimes but It always makes me feel better. Last year I had almost 300 lbs in body weight. And then one day I just started moving more, then running slowly and at the last I started doing weighted exercises and I was eating clean by following meal plan I got from Next Level Diet. Today I have 200 lbs and I am happy like I never been in my life.

Just in case the original comment is edited at any point, I am responding to this: "It would be great to see a comparison on how the body heals and improves muscle from exercise vs injury." . The "stress/recovery/adaptation" model is outdated and biologically inaccurate. The leading theory of adaptation currently accepted by experts in athletic training is the "fitness-fatigue" or "two factor" model. Adaptation does not occur as a response to damage done to the body (though evolutionary theorists may speculate that damage control is the reason adaptation mechanisms exist in the first place). Rather, adaptation response occurs independently of any damage or fatigue accumulated during the process. Correspondingly, fitness (the body's theoretical performance potential if fatigue were absent) is generally highest shortly after training (how long after sun exposure do you have to wait for your skin to darken?). Unfortunately, fatigue is also at its highest immediately following training, so the net effect is generally that overall preparedness (the amount of weight you are actually capable of lifting, how fast you are actually able to run, etc.) tends to be lower post-workout than it was pre-workout, at least after large-load workouts. . The adaptation model in which exercise causes "damage" to the body, with subsequent stages of "recovery" then "supercompensation", is incorrect. Any fatigue accumulated from training is coincidental to adaptation, and in my opinion, should be minimized (through proper training organization: quit training to or near failure unless you are a competitive bodybuilder looking to swell your muscles with fluid). For more information, I recommend "Science and Practice of Strength Training" by Zatsiorsky and Kraemer, as well as Pavel Tsatsouline's KZread channel and his numerous articles discussing the ill effects of training to failure. . I believe your question to be loaded (though that was not your intention), as damage to muscle tissue was never the cause of muscular adaptation in the first place.

@b1uezer

2 жыл бұрын

@@nickgrove3648 Even if muscle damage isn't the trigger for adaptation, and adaptation occurs directly after stimulus, muscle damage is still a part of the process. The two factor model even notes that muscle damage is likely a large part of the fatigue we feel as peripheral and central fatigue are mostly transient after a workout. The body does still have to repair damaged muscle, regardless of when the strength adaptation occurs, and that's what I'm interested in.

Older folks especially men (>70yrs in the studies if I recall) need a dietary protein intake almost what a younger man doing strength and even mild hypertrophy training would need just to keep up with the increased muscle breakdown of age - ie closer to 0.8 to 1g per kg just to maintain. I'm not sure if the mechanism is decreased anabolism from reduced testosterone or a true increase in catabolism

Skeletal muscles - Attached to the skeleton, enables skeleton movement controlled by our mind. Smooth muscles - Are autonomous muscles, so not controllable by ourselves. Those are found for example in the stomache, intestine and blood vessels. Cardiac muscles - Are built similarily to the skeletal muscles, but are also autonomous and do not fatigue, unlike skeletal muscle (that would obviously kill us).

That was the best talk I have heard on fast twitch and slow twitch muscles. Thank you! Keep them coming.

From Nigeria. And it’s been awesome going through your videos. Keep it up

Thanks a lot for putting out such detailed & informative videos.

These videos have gotten me more interested than ever in human anatomy. I’d love to hear the challenges of working in this job and the buildup to having it.

I absolutely LOVE your videos!! Whenever I need a refresher as someone in the medical field, I turn to this channel! Keep up the good work!

I was just at the gym and wondering about this stuff, and this was a great explanation. I intend to keep increasing my understanding of my own body

Great content, great analogies and general detail. Thanks for breaking it down!

Thanks Jonathan for yet another wonderful video of muscles and ATP process!! Your hardwork has been appreciated always and I thank the Institute of Anatomy as well to make these videos so fascinating and informative.

This channel was always amazing, but I feel like you gets are getting better and better! Thank you for sharing with us.

You guys are making some real content.. really appreciated

Excellent, well explained and new insights for beginners. Thanks you making the terms easy enough to grasp.

Just subscribed. Would love to hear more about the other fiber types you mentioned. My textbook didn't have much to say about them back when I was in school.

Its incredible to learn a lot about our amazing body with this videos... thanks a lot. Keep doing the great work guys ;)

Just learned all of this in exercise physiology. Seeing this videos make me so happy because I understand.

So well explained, thank you! Currently studying to pass the MBLEx and this touched on many points and was an amazing study tool.

Thank you for producing and posting this video! As someone who did not excel in biology in high school, this is a perfect refresher now that I have gotten more serious about fitness, athletic performance, and taking care of my body. It also harmonizes, and complements much of the information I have gathered over the last several months to a couple of years from a popular cycling podcast I listen to. You did make a statement in the video that created a question in my mind, however. You stated that muscles of greater cross-sectional area produce more power. Recognizing that this was probably an oversimplified generalization, my question, concerns the apparent conflict of interest, or perhaps theoretical physical impossibility, of the lightweight, high-power-output cyclist. In cycling, thinking particularly of road cycling, stage racers, grand tour riders, etc., a goal is always to maintain as light a weight as possible so that the power one is able to produce is moving less mass. How then, does a cyclist get stronger and produce more power, without bulking up and defeating his (or her) purpose? Probably a rudimentary question but again, biology and fitness are not my strong suits. Thank you again!

Your work is amazing.....highly appreciable....

As a Senior in Ex PHYS, this video was incredible. It explains the heart of our muscle physiology in a short and simple way. Really enjoyed it!

Loving the video, as always really informative and very well explained. Would've been cool if you also covered how slow twitch can convert into fast twitch but not the other way round (as far as I've learned), that might be good to know!

Terrific, as always. Bravo and thank you

Great videos! Very well explained. It would be really interesting to know what happens to the muscles and lungs when you do exercise at high altitudes and how your body adapts to environments with less oxygen.

Can you go deeper into the different types of hypertrophy? I would love to see an in depth video on myofibrillar hypertrophy vs sarcoplasmic hypertrophy.

Myofibrillar hypertrophy is the increase in muscle fiber size where the fast twitch fibers, which are 22% bigger and white because there's no oxygen containing blood in them, they run on ATP and creatine, increase in diameter and are more compacted to fire faster and with more force. This is actual muscle growth. The sarcoplasmic hypertrophy is the increase in muscle cell size only due to transient factors like glycogen storage and water retention. Your red, slow twitch fibers which rub on a combination of carbs/fats for fuel results in lactic acid, which ultimately causes the actin/myosin cross bridges to fail, but, it also induces a surge of anabolic hormones like testosterone, growth hormone and insulin like growth factor-1. Every gram of glycogen pulls in approximately 2.7 g of water into the cell to flush out lactic acid, ammonia and creatine will so pull water into the muscle cell. This will give you a pump but, if your adaptation is only one of endurance or failure at good form past 15 reps where the weight isn't heavy enough to illicit your type 2 fibers for growth, or a weight you can handle really slowly or just stop at a number where your body is already that strong and has no reason to change, you will still feel a pump from lactic acid and using more glycogen but, the adaptation you are illiciting is one of endurance at that point. I could go on about what adaptations, time, body's use for fuel, and the pathways it's using but, this has probably bored you to tears. I am a certified trainer, sports nutritionist, nutrient timing and expert on training and nutritional sciences and supplementation.

@@crush41gb How do you explain muscle growth in Keto diet people then? I only experimented with basically a no carb diet while working out and I still gained muscle. WAY different on the feeling of energy though. Felt more ''flat'' during workouts with no explosive like energy but I could handle 3-4 different exercises for a single muscle group being a natural (no enhancements. No drugs nothing. Just food). I'm talking at least 10-12 working sets just on a single muscle such as my Bicep or Tricep.

@@wombat5252 Your body will adapt to using ketones, the incomplete breakdown of fats, fuel in 2-4 weeks so strength and endurance should be normal to speak at least for a time. You can still drive a car full blast on a half tank but, not as long. You would still get creatine in foods on keto like red meat and that will still give your fast twitch fibers the fuel to get some size and depending on your protein intake, the only nutrient that can build and repair muscle, then you can still get bigger, leaner and stronger. If your goal was endurance, you may notice a big difference. This is actuality what's occurring in your second wind. In a low intensity aerobic activity you may take 20-30 minutes to deplete your bodybof glycogen/carbs then your body begins breaking down protein to convert into glycogen through gluconeogenesis.

Your flat feeling is because you have only roughly 25-50 g. carbs daily so no water being pulled into the muscle cell.

Was so excited to see this! I love these videos so much! So educational!

Thank you for your time and help ✌️💥

Not gonna lie at first I was kind of thinking into ditching the video 10 seconds in but as it went on you really catched my attention so very interesting and informative this will definitely help more in my training and I thank you for the additional knowledge you provided to us people of the internet! I've subscribed to your channel and liked the video cheers brother!

Smooth muscle and cardiac muscle. Well type of muscle depends on different basis considered. If basis is colour(due to myoglobin) - red and white muscles. If basis is ability to contract in our will - voluntary and involuntarily muscles. If basis is location - skeletal and visceral muscles If basis is microscopic striations - striated and non striated muscles.

I am not even studying anatomy but I find these absolutely fascinating. Thank you and your team for creating such informative videos so i can fill out my stores of information that I will undoubtedly forget by the time my head hits the pillow, but maybe, just maybe, some of it will stick in my sieve of a brain and I can regurgitate it later to sound smort. ;-)

Simply the best coverage!

great video, gradually expanding the mechanisms involved

This is one of my favorite channel, love content and the way it's delivered. Really minimalistic quality, nothin but pure interesting and factual informations about the body and its many inner mechanisms !! I think I would like a video on the foot, like there's this saying in french that goes " etre bete comme ses pieds " which roughly translates to being dumb as your feet, but our feet keep us upright all day long and honestly I suspect a very high nerve ending concentration in them cos walking is a perpetual and controlled disturbance in our centre of gravity's position and our feet deal with providing the most primal informations to make them calculations to our brains and keeping us from crumbling to the slightest obstacle in our way !

*5:47**; the mitochondria is the powerhouse of the cell!!*

It's amazing how cardiac muscles beat tirelessly, could you imagine if those properties applied to skeletal muscles?

The other two types of muscles are the cardiac and smooth muscles. The cardiac muscle is also a striated muscle however it's only located in the heart and is specialized to never fatigue or tetanize. Smooth muscles are non-striated muscles that are present in the visceral organs such as the intestine or bladder or even within the walls of blood vessels and they can serve various functions.

Great video...looking forward to more videos about our body's adaptations to fitness. One question on muscle fibers. You mentioned the adaptations of slow vs. fast twitch muscles. You also mentioned that the percentage of slow vs. fast twitch will vary based on the muscle as well as from person to person. Can that unique individualized percentage be altered by significantly altering training and diet? Could an endurance runner shift their training completely and become a power lifter? It seems to me that people are genetically geared one way or the other.

Hearing how the most common supplements, like creatine, effect the body would be cool. When you started talking about ATP I wondered if you were going to mention it.

Sending you more positive energy and love ❤
