You’ve heard the most sure-fire approach to fitness is to “keep the body guessing,” but what if we said the same was true about flexibility? We know that fascial fitness is created in response to stress. And research, led by Robert Schleip, Ph.D., at the Fascia Research Project in Germany, suggests that fit, resilient fascia results from stressing our tissues in varied ways—stretching, compressing, and twisting them in multiple directions, at varying speeds, and under different loads. Looking more closely at myofascial tissue, we can start to understand why.

Within our muscles are spindles that measure changes in muscle length, and each of these spindles has about 10 sensory receptors in the surrounding fascia. There are four different types of these myofascial mechanoreceptors, which measure mechanical load on our muscles and fascia and each respond to different types of stress. Let’s breakdown and how we can target each of them on the mat.

4 Ways to Work Fascia in Yoga Practice

1. Type of receptor: Golgi tendon organ

How to work it in your practice: Holding

Golgi tendon organs are receptors that measure the load on muscle fibers. They are responsive to muscle contraction and also allow muscle tissue to yield when you hold long, deep stretches. One way to stimulate these receptors in yoga is through strong, held positions (like Warrior poses), where muscles are engaged in a lengthened position.  Think of the your quadriceps in the bent front leg and the adductors on the inner thigh of the straight back leg as you hold strong in Warrior II. The benefit of this type of work is a decrease in muscle tonus—or in layman’s terms, our muscles feel more relaxed afterward. We’ve all experienced how much easier it is to melt into stretches at the end of a yoga practice after standing poses, compared with how it feels at the beginning.

2. Type of receptor: Paciniform ending

 How to work it in your practice: Floating

Paciniform endings are receptors triggered by changes in pressure and vibration. They are particularly responsive to bodywork like massage, Rolfing, or Bowen Therapy, but in yoga practice we can stimulate them through light, springy movements, such as floating forward from Downward-Facing Dog to a Forward Fold or into a Handstand. The benefit of this type of work is a keener proprioceptive, or kinesthetic, awareness.

3. Type of receptor: Ruffini endings

How to work it in your practice: Melting

Ruffini endings are receptors that measure sustained pressure and respond best to gentle, consistent stress, such as that created by Yin yoga postures and myofascial release techniques. They are particularly receptive to shearing force (a stretch running across a muscle rather than down its length), so multi-directional poses and myofascial release techniques that work across muscle fibres (rather than down their length) are most effective for these receptors.

4. Type of receptor: Interstitial nerve endings

How to work it in your practice: Flowing

The most numerous of the receptors are the small interstitial nerve endings, which respond to varied triggers including load, pressure, shear forces, and even pain. These receptors respond to varied, fluid, graceful movements, like vinyasa flow. The benefit of this type of work is increased blood flow, especially to the periosteum, a vascular connective tissue surrounding the bones.

How much of each type of stress we need depends on our habits, lifestyle, job, and natural body type; some of us are naturally stiffer in our tissue consistency and need more melting, while others are more supple and need more holding. The key piece of information to take away from this is that we all benefit from varying how we challenge our fascia, rather than just sticking with the same postures or sequences over and over again. Variety really is the key to creating and maintaining fit and healthy fascia.
