This is a great way to digest what's been talked about in the longer podcase episodes. Great work!
Very informative video, fantastic work!
Great content, and great presentation! Thanks, dr Wolf!
This format is great. I suspect this channel will grow a lot.
Honestly, it just makes much more sense to release tension for just a second or two to flush out some of the burn and immediately crank out another 3 or 4 controlled reps, still focusing heavily on the eccentric
Does stretch-mediated hypertrophy have a dropoff and if so, is it a logarithmic curve like with standard strength training or is it more of a cliff where once you meet the limits of your joints, there's no more to be gained? Edit: well shit, it looks like you answered this later in the vid. nvm.
42617 good content mate, love your content!
what camera are yall using to record Milo ?
Dante Trudel was talking about 20+ years ago. Check the extreme stretching in his DC Trading
PLEASE do a video on leverages and whether or not they matter and should be considered in exercise selection. E.G the lats lose leverage at the bottom of a pullover but they are most stretched, should we do the pullover as the lengthened biased resistance curve and the full lengthening of the muscle are beneficial enough to override the lack of leverage? or should we do an illiac pulldown instead because leverage is really important...

Aren't they least stretched at the bottom of a pullover? Regardless, pick exerices that you like, can progressivly overload and that don't mess your joints up. If you then want to get nerdy with force curves within different exercises/ROMs then go for it. Pullup/pulldown for vertical lat stretch, supported row or deficit rows for horizontal lat stretch.... kinda job done really. Bicep curls; standard barbell for the typical ROM and then cables or preachers or similar for lengthened stretch. Boom. No one exercise is going to do everything, just overlap them to make sure you get everything covered.

Perfect question but I think I got the answer for you (I am a PT). As you might have seen in yourself and others in the past, when you try to statically stretch your lat, you end up in a position that is not completely overhead but more like 20-30 degrees from it. I know your idea is that "Lats extend the humerus, therefore I will flex it all the way so I can stretch it, same logic with pecs", but the lats insertion points are actually the furthest during 20-30 degrees away from full flexion. Another funny mechanic is that they also have no leverage during full extension.

Eh people are overreacting on all that. I’d rather pay more attention to their length-tension relationship. There’s a lot of factors that come into play for a muscle to be the “prime mover” best to just line up the muscle with the resistance I’d say.

But some are quite "toned" and look "fit". That always puzzled me, since I was the guy who said "girls who look good in yoga pants don't do yoga". Now it makes sense, it's due to all that stretching alone., which is enough to reap some results.

My thoughts exactly. Just like long distance runners aren't huge, but sprint bikers have big legs...
Honestly, if it stimulates or not, being able to say "Stretch-mediated hypertrophy" as a means to indicate to someone that the person is missing out on gains because their shortened partials doesn't allows the muscle to stretch, thus, they're missing on their stretch mediated hypetrophy gains, is really good and just feels right. This video seems more like you're trying to say that there's much more to lengthened partials than just the stretching part and that's okay, but I still believe most peoples problems in the gym is not getting a full stretch or full rom, and long lengthened partials should be used more as a means to scientifically show what that person is probably missing out than an actual way of training (at least for beginners).
A more intresting question is if this stretch mediated hypertrophy be usefull for advanced lifters, so if the gains slow down for us with traditional training, then having some machine stretch our muscles result in even further hypertrophy?

42617... If this is how you yourself are training, can you share your measurements and results over a month time frame. All these studies reports would mean more if we see actual results on video.
would the term "eccentric-mediated hypertrophy" be more appropriate to call lengthened partials due to the amount of time the muscle is exposed in this contraction? i just thought it'd make sense since giving more emphasis to the eccentric does lead to more muscle growth. anyways, thank you again for a banger video, Dr. Father Milo! bless up.

I don't think it would be specific enough. One could train with only the shortened half of the eccentric. It would be "eccentric mediated hypertrofy", but shortened partials, instead of lenghtened ones.
@guiguspi

Also usually lengthened partials are done with concentric and eccentric, even though eccentric is understood to do most of the hypertrofy, I don't think it is established that if the focus on the lenghthened portion improoves the eccentric stimuli, the concentric one, or both.

I mean, it doesn't really have anything to do with the eccentric phase specifically. The amount of eccentrics or even proportion of eccentric:concentric muscle actions being performed is typically similar between full ROM and Lengthened partials for example... so it's even less accurate to call it eccentric-mediated, IMO

@@kaderux I'm so confused. Produce more muscle in the supraphysiological level? Is it even possible to produce more muscle than the body is capable of producing? Outside of fluids and myostatin inhibitors and other interventions. Just pure, 100% natty muscle protein synthesis, can it be supraphysiological?

The people in the stretching and flexibility space say so. The hypertrophy you get is length though. What you’re describing is what they call dynamic stretching. So like going as far into a split as you can and holding yourself there. (Your bodyweight is the load). This lengthens your muscles and makes them stronger in that new range. Literally longitudinal hypertrophy. It’s probably not a massive amount of muscle by bodybuilder standards though. It’s done to increase flexibility and not be a wet noodle in your new end range positions.

Isn't this just dicing up some word salad? Did anyone actually ever think they could get jacked just by stretching? Every time I've ever heard stretch-mediated hypertrophy used in discussion, it's always been in the context of the lengthened portion of ROM in resistance training. I get that Milo is bringing up other nuance as well, but really, if it's the stretch under tension that increases hypertrophy in lengthened partials over say full ROM, that really seems correctly described as hypertrophy mediated by stretch ^^

They are just giving the pedantic argument that there is some preceding definition of stretch-mediated hypertrophy in the literature and somewhat ignoring the adaptability of language to encompass new ideas.
@JyotiDas-72

No. Because if you look at the literature on training at longer muscle lengths the groups training at longer muscle lengths often aren’t even training at lengths long enough to create any stretch whatsoever. It’s often stuff like squatting almost to depth vs squatting well above parallel but neither group is squatting as far down as you can go. So it's completely accurate (and not even in a pedantic way, just in a "if the word stretch means anything at all" way) to say that stretch is not involved whatsoever in the data we see on longer muscle length training being better than shorter muscle length training.
@JyotiDas-72

@@blaizenflameIt's actually not pedantic at all. In the literature on longer muscle length training the longer muscle length group often isn't training at a length long enough to generate any actual stretch at all. So both groups are having the same amount of stretch (namely, zero). Even if you ignore the technical definition of stretch-mediated hypertrophy, you would agree that for it to mean anything at all there would have to be a "stretch" component to the lengthened muscle length training, right? But the data isn't actually studying training with a stretch vs training without a stretch. It's usually comparing training at a longer (non-stretched) average length vs a shorter (non-stretched) average length. So saying stretch isn't involved isn't pedantic even slightly.

@JyotiDas-72 what do you call a muscle that is longer than a shortened muscle without using the words long or short? Hmm... stretched comes to mind. Words are adaptable, and it is completely pedantic. Similiar, I am not sure any literature actually defines by synthesis what stretch-mediated hypertrophy or long-muscle length is, so the basis of this argument is just opinion anyway.

Do we have an official and accepted definitions for "stretch"? Without a better understanding of the mechanisms of stretch mediation, it seems unlikely we can have a very solid definition. I agree that it's probably not very helpful to conflate research using static stretching to lengthened training or lengthened partials, but I question whether we have a understanding of the mechanisms and accepted definitions to say whether "stretch mediated" is or isn't a component of training at longer muscle lengths. At what length is a sarcomere officially "stretched". Is it the sarcomere length, or the tension on specific structures "titin, nebulin, the extracellular matrix". Is it the activation of specific mechanic receptors etc etc. Is this an attempt at a working definition that should be named "static stretching mediated hypertrophy"?
How about including loaded stretches🤔 instead of lengthened partials🙄
