Fascia is basically tensile, connective tissue containing all of our musculature in a giant web. Instead of having 600 muscles, we have 1 muscle in 600 myofascial pockets. Itโs certainly an interesting way of looking at the body as one interconnected structure where nothing can move in isolation.
Point is, fascia is a thing - itโs not a money-making pseudo-concept created by homeopaths. And it can certainly get too stiff, distorted, dehydrated, or ridden with painful trigger points or โknotsโ as people tend to call them. However, when we talk about โmyo-fascialโ release it becomes a bit of a misnomer seeing as fascia is extremely strong and stiff โ you'd need >900 kg of force to make significant permanent change in its length or structure. Unlike muscle, which one can passively lengthen (stretch), fascia is non-contractile, collagen-rich, and designed for tensile strength and stability. Soโฆ do we actually need to โreleaseโ it or (god forbid) stretch it?
With things like trigger point release, foam rolling and any kind of manual pressure is more to achieve an inhibitory response within the painful region, be it fascia or muscle. However, what we can do with fascia is:
- Redistribute interstitial fluid (fluid in and around the fascia) and rehydrate it.
- Improve gliding properties - the human body is comprised of layers and layers of โstuffโ, creating anatomical fascia-muscle-fascia sandwiches. The layers can get a bit stuck together, which can restrict and inhibit movement.
So generallyโฆ itโs not about mashing your IT band as hard as possible and expecting your knee to stop hurting because it somehow โreleasesโ. We cannot structurally change fascia much. But what we can do is change certain properties of it to facilitate relief and therefore simply alter your perception of pain... have fun stretching!
