Another Argument for Slow, Gentle Stretching

stretching fascia

The Fascial Network

In Yoga classes, we hear and talk a lot about muscles—which muscles are stretching or contracting in a certain pose, how to stretch or engage muscles, how poses effect certain muscles, etc. This is because it is our muscles that move our bones via their paired contracting and stretching actions.

As a teacher, it’s essential to understand how muscles move our skeleton. Having at least a cursory understanding of the origins and insertions of the muscles that move our structure through space is important. In Yoga in particular, knowing how to stretch muscles safely is essential.

It takes 30 seconds of stretching for a muscle to become longer. Embedded in each muscle fiber bundle is a sensory nerve called the muscle spindle sensory nerve (MSSN). The MSSN’s job is to sense when a muscle is being stretched beyond its capacity and to send a message to the spinal cord. The spinal cord then sends an impulse through the muscle’s motor nerve that actually contracts the muscle in order to keep it from overstretching. After 30 seconds in a stretch, however, the MSSN habituates to the muscle’s new length and allows it to adjust itself to that new length.

If muscles were all that predict our flexibility, the 30-second stretch would be enough to effect powerful change. And it is certainly one component of stretching. However, anatomists, physiologists, body workers and Yoga teachers are now beginning to understand the role that fascia plays in flexibility.

Fascia is a connective tissue layer that lives virtually everywhere in the body. It covers the muscles, and weaves itself into the connections between muscles and other muscles and muscles and our vital organs. Until recently, fascia was something that anatomists cut away in order to get to muscles they could dissect and categorize. Now, fascia is recognized as a living organ all its own.

Ida Rolf, the creator of the body work called Rolfing Structural Integration, recognized the importance of fascia. Her method is entirely focused on fascial balance and release.

Tom Myers’s 2009 book Anatomy Trains brought fascia into the limelight to wider community of body workers and movement therapists, presenting a “whole system” view of the whole-body connections among muscles within the fascial net. You can find out more about the Anatomy Trains system here.

Even Running Times has begun to explore fascia and its relationship to movement and exercise-related injuries. Here's a recent article that gives a simple, practical explanation of fascia and how to keep it healthy and stretched.

For a look at how fascia thickens and loses pliability when you neglect it, here’s a video by anatomist Gil Hedley. (The demonstration uses a medical cadaver, so if this sort of thing makes you queasy, this demo may not be for you.)

Of particular interest to me as a Yoga teacher and practitioner, is the idea—supported by Ida Rolf and others—that the energy meridians reside in the fascia. The implications of this are staggering. This means that by tending to our fascia, we can effect change in the physical, mental/emotional and energetic koshas.

Years ago, I heard that if you want to make a change on the physical level, you must stretch for 30 seconds—ah yes, the muscle spindle sensory nerve. If you want to effect a change on the pranic level, you must stretch for 3 to 5 minutes.

If the meridians reside in the fascia, and contracting and stretching fascia can affect the meridians, how can Yoga help? This excerpt from the Running Times article suggests that slower-paced Yoga styles such as Yin YogaIyengar and Restorative Yoga may be effective ways to access the fascia, and therefore the profound effects of meridian work:

“STRETCH YOUR FASCIA: Once your fascia has tightened up, it doesn’t want to let go. Because the fascia can withstand up to 2,000 pounds of pressure per square inch, you’re not going to force your way through, so stretch gently. Fascia also works in slower cycles than muscles do, both contracting and stretching more slowly. To stretch the fascia, hold gentle stretches for three to five minutes, relaxing into a hold.”

I’m just beginning to learn about fascia, but I’m very excited to explore this new physical avenue for effecting deep transformation, via stretching and stabilizing on the fascial level.

What do you know about fascia? How does your Yoga practice support stabilizing and stretching fascia?

    I love fascia! Fascia is so amazing and is not talked about nearly enough. Fascia is such an important attribute of the human body (from your head to your toes). While the human skin is known for keeping our inner contents internal, fascia is responsible for keeping our inner contents in place. I think that the most fascinating scientific research is now being done about the importance of fascia. I really enjoy learning about the correlation between energy medicine and fascia. Many people can benefit from a deeper understanding of the connection between the meridians and the fascia within our own bodies. Anyone who has experienced Myofascial pain understands the significance of pain reduction and prevention. I personally believe that bodywork and slow gentle stretching of the fascia can relieve pain associated to a past injury, inflammation and/or poor body mechanics. I also believe that yoga can provide pain relief and assist with injury prevention, when practiced correctly. I think that you have chosen some excellent references for those who would like to learn more about fascia. Thanks, Charlotte.

      Thanks for such a great explanation of fascia's important role in the body. I'm just starting to read Anatomy Trains. I'm excited to learn more. I've become interested in learning more about subtle energies, and I think fascia is the physical key to this.
