So the deep fascial tissues, they are surrounding our muscles. But we don't just have one layer of deep fascia. We have multiple layers of deep fascia that glide upon each other. And then we can get into the interior architecture of a muscle itself. Each muscle you have is comprised of additional multiple layers of fascia, and these are subdivided.

Like each muscle cell is surrounded by an endomysium. That's like if you have one little orange, you know, in the orange you have the little tiny segment and it's surrounded by that cellulose filament and inside it's just juice. The same is an analog for your muscle and its endomysial fascia. Then when you have groups of these muscle fibers, you're wrapped in yet another layer called perimysium.

But you must be able to have movement between these epimesial sliding filaments and the paramesium. And then the paramesium gathers together in lots of bundles. And then we have a real muscle, and that's wrapped in even more fascia. That's called the epimesium. And these epimesial bundles is what we call a muscle. And that muscle and its epimesium must move. It must have differential movement.

amongst the other muscles that it's next to. And this is called glide. We have glide between all these different things. And so when you invest a tool into these tissues, we're stimulating cells called fibroblasts, which produce the collagen and elastin environment. We are stimulating cells called fasciocytes, which are chiefly responsible for keeping you slick inside.

They produce an abundant amount of a substance called hyaluronan. You're also manipulating fibers. You're creating tension with your compression. You're creating stretch, tension, pull on these different fibers that these fibroblasts are sensing. And when the fibroblasts start to sense activity, they will start to realign things or tear things apart depending depending on what you're trying to do.

So, for example, one of the, I guess, the old myths that people kick around all the time is, is massage or self-massage breaking up scar tissue? Well, yes and no. Scar tissue is comprised of very, very strong fibrils of collagen type 1, and it is necessary to be there to stabilize an area that had been breached. The scar itself on the surface may look bumpy and weird and a little bit ugly.

And there are some things we can do with friction that can adapt that tissue, that can maybe soften the scar a little bit. But the scar is necessary to act as a permanent suture for the rest of your life. But typically what we're seeing on the surface of the body, the scar is really the tip of the iceberg, depending on how far down that wound was into the body.

Now, if we have a breach that goes all the way to the bone, like I'll use myself as an example. I had a total hip replacement almost eight years ago. And so, you know, they had a saw that greater trunk hander off and there were many layers that were breached. So there's a scar path that goes from skin all the way to deep, even though it was a very elegant surgery.

You're left with a scar path post-surgery. And ideally, you want to be able to do movements and massage that that allow the fascial tissues to restore glide so that the muscles can return to their correct length tension relationships. So when we are stimulating these tissues, We're doing many different categories of things.

One of my personal favorite reasons to do self-myofascial release or to do foam rolling is to enhance one's proprioception, to enhance one's ability to know where they are in their own body and be able to know how to move forward or how to take the next step, to know where you are in space. That proprioceptive enhancement has been shown to also have an inverse relationship to pain perception.
