Muscle Function, Adaptability, Hypertrophy, and Metabolic Health: Comprehensive Overview

Exercise 1:14 0
“in general the way that humans move is muscles will contract and muscles actually at the end of them will come together to form a tendon those tendons actually connect to Bone so when you contract muscle it pulls that connective tissue the tendon that pulls the bone and you move”

“the more nuclei you have the more control centers to have the easier it is to respond to stressors, damage adaptations Etc that's why skeletal muscle is so uh again adaptable to various whether this is good stimuli or bad stimuli like in the case of space flight or physical inactivity or whatever you want to be.”

Exercise 6:24 0
“you've got what we call the contractile units and so the things that make your muscle fibers contract together and on top of each other are actin and mein and so these are two molecules that kind of reach up the mein grabs the actin it pulls it together um smashes it literally on top of your and that's why when you Flex say a bicep muscle it actually gains height because you're stacking things on top each other and that requires the muscle to go vertically.”

“Felines and animals and bears and stuff we've done biopsies and stuff on Bears H do have the 2B um urines have 2B and so most other animals have four distinct ones they have a really really fast one these B's are Ultra fast uh 2x is pretty fast two a is slower but fast and then one is slower so if you run the entire Continuum it pretty much lines up so the ones that are pure type one have generally more mitochondria and they are less fatigable they don't produces much force um relative to well they do relative to size but uh they're slower and they do that as you move to 2A and to 2x they become faster but they become more fatigable because they're more relying upon on um glycolysis in carbohydrate metabolism.”

“how modifiable is that distribution is it purely genetic or is there a trainable component to the ratio of fast to slow twitch fiber in a given muscle it's extremely trainable um it's just comes down to exposure which means stimuli and time and the more stimuli you give it the more time you give it the more uh it will change.”

“hyperplasia is when you would grow a new cell and that is very very uncommon in normal human situations it can happen with extreme Ecentric training um looks like it probably happens with a lot of exogenous testosterone use over many many years um but outside of like sort of extreme examples um you can get it in cell culture and you can get it in animal models but in human like normal situations hyperplasia is very uncommon”

“just the standing Circle starts to expand and so probably the the biggest explanation for why muscle increases in its diameter is exactly that you've put more proteins in the contractile units in order to maintain optimal spacing so they can reach out and grab each other and pull in for contraction the whole thing needed to space out a little bit.”

“Andy when you when you experience contractile hypertrophy based on everything you've just described it sounds to me like that comes with contractile Force as well because you're putting more hooks basically you know you're basically creating more anchors I.E act meas and filaments to grab and contract is that is that essentially you know to A first order approximation a true statement.”

“in general especially early in someone's exercise and career as you get stronger you'll add more muscle mass and those are very highly length now that that R score is not 100 it's not 99 like there it's not 100% the same thing and we'll differentiate that later optimizing for muscle growth is not the same as optimizing for strength optimizing for strength is not the same for mus optimizing for muscle growth so at some point they start to diverge more and more and more but at the very beginning they're very tightly linked and so if somebody just wanted to be economical in their training you could probably get a little bit of both Well you certainly would get a little bit of both if you wanted to optimize for one then that is a little bit different and we'll distinguish all that we'll talk about that you know later now as you continue on with your training career and you get stronger and stronger and stronger then the link between muscle size and strength does start to go away but it never goes away entirely because of exactly what you mentioned if you're tacking on more contractile…”

“you would have to do to answer your question is build the technical skills and then get strength doing say a front squat and doing a push press or an overhead press or stuff like that a more traditional why you're building the technical ability because what's going to happen is you won't have the technical ability to even get heavy enough on the snatch and clean a jerk for quite some time because you're going to be so limited by technique rather than strength or speed”

“if you look at Peak power production so when I say this um you take the force so how much load is on the bar and you take the velocity on and we plot it against each other okay at some point if it's too light but very very heavy not powerful opposite in the Spectrum same thing happens so the question is where is that crossover point which there's enough power or there's enough velocity and enough Mass well this is actually hyp specific to the exercise and since we're on the power the weightlifter and kind of getting on power if you do an exercise like a bench press or even like a tricep extension that's probably going to happen at somewhere like 30 to 40% of your one rep max okay you'll have Peak power when you have about so if you can bench press 200 pound and you want to train power on the bench press you should probably put 80 pounds on the bar something like that 30% if you move up to a more compound Movement Like a squat instead of being at 30 to 40% it's more like 40 to 50% for most…”

“there's a training concept called cluster sets and so clusters have been shown uh to be highly effective for strength power and even hypertrophy surprising enough but what a cluster is is this let's say you were going to do six repetitions in your set let's say five just to keep it consistent five reps you could do you know one 1 2 3 4 5 no breaks in between or a cluster set says you're going to do one rep you're going to take a 5 to 20 second rest you'll do the next rep 5 to 20 5 to 20 5 to 20 so you're still doing quote unquote five but you might but you have micro micro brakes that's what clusters are and they are extremely effective because they do exactly what you just mentioned the quality and when I by quality here I mean power output velocity output Etc goes up because you reduce fatigue in specifically reps three four and five those will be much higher quality so the old way we would say it is instead of getting five reps you get five first reps”

“as long as you keep these high quality now if you are doing these two fatigue set to 20 you know 5 Seconds rest in between then like then that's a whole different thing but if you're doing these non- fatiguing which is what you need to have for power and skill so this is a very important point for power and skill development they need to be non- fatiguing if if you're if you're getting to fatigue you're not doing either one of those things now you can get to fatigue if you're trying to produce a different adaptation which is maintenance of power through fatigue which is fine but that's not the same thing you're not going to improve your Peak Power by fatigue doesn't happen”

“your skeleton muscle needs to have muscular endurance so it needs to be able to do something for 20 repetitions in a row or something and this is very important for again walking up 15 flights a step or 15 you know steps 20 steps this is not going to be cardiovascular limited it's going to be limited by the local muscul endurance it's going to be limited by your strength actually.”

“what makes it so elegant is it's actually strength to weight ratio right so you might even say well but I am kind of strong and it's like n not for your weight you're not and the gravity now makes it your strength to weight ratio is not high enough and correct that's that's that's where your fatigue is coming from.”

“injuries exercise induced injuries happen in a couple of ways um it's very very rare that it's muscle that's the problem okay the only problem that you have with the cardiopulmonary system or cardiovascular system is system fatigue that's not really its fault right systemic fatigue so if you're not overdoing it globally and this would be your run down this is maybe you're getting sick really often any number of hormone Cascades or out of whack cortisol testoserone estrogen all off like things like that mood can't sleep appetite like that is those are some of the markers we look for of global fatigue so if that's not what we're talking about here you're talking about I got hurt through my back go knee hurts yeah neck is this knee is that back is that right what your talking about is joint all right so the only reason joints really get hurt is repetition over bad movement patterns so as long as you're moving well in those joints or not moving well depending on the joint not moving at all rather then you can really do unlimited amounts of volume theoretically until the point you hit systemic fatigue because…”

Exercise and Muscle Function

Muscle function is fundamental to human movement, involving contraction that pulls tendons connected to bones. Muscles also facilitate essential health functions like blood circulation, ensuring oxygen and nutrients reach all body parts effectively, aided by cardiovascular health benefits from activities like sprinting and endurance training.

Muscle Adaptability and Hypertrophy

Muscle tissues are incredibly adaptable and have cores termed nuclei that react to physical stresses. This adaptability is evident from resistance exercises, leading to muscle hypertrophy. Training regimes can be modified to enhance muscle fiber type conversion, emphasizing the malleability of muscle fiber distribution based on exercise intensity and duration.

Molecular Basis of Muscle Movement

Molecular interactions between actin and myosin within muscle fibers facilitate contraction, resulting in movements like the flexing of a bicep. Understanding these interactions aids in improving exercise and rehabilitation programs to maximize muscle efficiency and growth.

Muscular Health and Metabolism

Muscle tissue significantly impacts metabolic health, storing glucose efficiently. Ensuring adequate muscle mass through strength training is crucial, evident from the metabolic benefits discussed.

Training Guidelines for Strength and Hypertrophy

Optimal training involves understanding the distinct demands of various muscle fibers. Slow twitch fibers benefit from endurance training, enhancing size and fatigue resistance, while fast twitch fibers prioritize power and speed with a balanced approach to hypertrophy and executions like cluster sets.

Systemic Impact of Training

Training affects more than muscle mass; it significantly impacts systemic health aspects. Proper technique and incremental loading prevent injuries, while structured workouts optimize cardiovascular functions by pushing towards maximum heart rates and sustaining activity beyond durations critical for health, demonstrating the expansive benefits and considerations encompassing effective exercise regimens.
