Reset the Body

For those of you who regularly practice yoga, especially restorative based classes, you’ll be familiar with the calming and grounding feelings you can experience after class. I remember the first time I felt this relaxed, yet focussed, state many years ago from a candle light yoga class (an instant love affair for me as my natural disposition tends to be one of a anxious Chihuahua wound up on caffeine).  It wasn’t until years later in my yoga training that I learned some of the physiology behind this process..

Part of the calming effect had been from practicing a certain pose called Viparita Karani or legs up the wall.

This pose is known for its ability to ease anxiety and stress, and I began to wonder, what is going on in this posture that leaves me feeling so relaxed? My research led me to an article on treating adrenal exhaustion, which explained how inverted poses, done in a restorative way, can calm our overly stressed and anxious bodies. Here’s how it works:

The sympathetic nervous system, otherwise known as the fight or flight system, is responsible for releasing adrenaline in our bodies. It winds us up by elevating the heart rate, increasing blood pressure, tensing the muscles, and increasing blood flow to the brain for increased alertness. This system is good for emergencies, but when activated chronically such as in times of high stress and chronic pain the hormones released by the adrenal glands will slowly break down our bodies and immune system and leave us feeling wound up and unable to sleep, which ultimately leads to a whole host of other problems.

When we invert our bodies there is an increase of blood flow from the lower half of our bodies to the upper half of the body and specifically to the baroreceptors (blood pressure sensors) in the neck and chest. When the baroreceptors are activated by an increase in blood pressure they trigger a reflex called the baroreflex which reduces nerve input into the adrenal glands, slows the heart rate, slows brain waves, relaxes blood vessels, and reduces the amount of stress hormones circulating in the bloodstream.  All of which shifts the body towards a calm and relaxed state, facilitating sleep and regeneration of the body (key ingredients when dealing with injuries, pain, and insomnia).

This process of unwinding the sympathetic nervous system takes time, so for therapeutic purposes, find an inverted position that is restful, such as a modified Viparita Karani where the legs are elevated over a surface such as a bolster or stool, or even over the end of a couch as shown in the image above. Aim for 15 minutes or longer and try elevating the pelvis slightly higher by placing a folded blanket or bolster underneath the hips for a more effective inversion. For further relaxation benefit, try lying a heavy folded blanket placed over you abdomen/chest (also shown above). Give this posture a try and notice how it leaves you feeling calm, relaxed, and ready for rest.

Winging Scapulae

If you are teaching a class and you notice one of your student’s shoulder blades sticking out away from the rig cage, otherwise known as winging scapulae, this client may be dealing with weakness of the serratus anterior muscle.

The serratus anterior muscle is responsible for holding the shoulder blades snug against the back rib cage.  When activated they move the scapulae out and away from the spine.

It is not such an issue is the student’s blades are winging at rest, it is most important to identify winging during movement, e.g. raising arms over head or in plank position, since this identifies them as functionally unstable.  If this is the case, the student will benefit from strengthening the serratus anterior muscle because winging can lead to impingement (descent of the coracoacromial arch) and decreased ability for the rotator cuff and other muscles to generate normal strength – ultimately leading to shoulder problems during their asanas.

To best help the student with winging scapulae, encourage them to consult with a qualified exercise therapist or physiotherapist as he or she will likely need a comprehensive program addressing scapular instability.  However, I’ve included one exercise that you can teach your class to target this important stabilizing muscle.

Wall Pushes
Have them stand facing a wall and place their hands against the wall directly in front of them (plank position against the wall).  Instruct them to move their chest away from the wall, keeping the hands pressing into the wall.  Monitor their upper backs to confirm their scapulae move out and away from the spine, and ensure the client keeps a relaxed and even shoulder posture.  Click image (right) for demonstration.

Once the motion has been learned, have them repeat this exercise leaning into the wall on their elbows, with the elbows as high as possible. This new position removes the help from the anterior deltoid muscles and helps isolate the action to the serratus anterior.

Happy planking!
