We are taking a muscle and stretching it basically with a weight.
We're tying a weight on a wing.
Yeah, let me see if I can do this in human terms.
Let's get on an incline bench and let's put 120 pounds in each hand and look up at the ceiling in pain for seven days.
So you can do this work.
And you will hypertrophy, I guarantee you.
100%.
You don't drop the weight.
And if your muscles don't rupture.
100%.
And this is getting into some key topics that are at the forefront of physiology that my good friend Troy Hornberger is working on at Wisconsin, which gets into not only do we see some radial hypertrophy, but now we're seeing...
the addition of sarcomeres in series and longitudinal hypertrophy which is again going to be a very hot topic um and not only that but okay how are the sarcomeres increasing in series meaning how are we lengthening the myofibril in the cell how are we making the spaghetti noodle longer longer and troy is doing exceptional work in that area um so he has a pre-print published
more or less indicating that the anabolic signaling response to making the spaghetti noodle bigger in diameter is canonical mTOR signaling, but longer is not mTOR signaling.
It's some other signaling cascade.
More to come there.
Troy also has some crazy awesome images showing how we have the addition of sarcomeres with longitudinal hypertrophy, as well as how we have the addition of myofibrils with radial hypertrophy.
So if you geek out about our conversation, Andy and I's conversation, follow Troy Hornberger's work.
He is doing it.
He is driving the field in this area, if that makes sense.
so brad brad schoenfeld right so they did interset stretching and showing uh it was like a somewhat uh pretty decent effect uh when you did interset stretching versus not on hypertrophy outcomes using the ultrasound this is human so this is you lift some weights and when you're resting you sit down and stretch the muscle yes now uh and then danny plotkin one of my students and dakota t did that they
