Know Your Body











Fascia is a connective tissue that is found in all living animals, there are different types of fascia for different purposes, and it can be found around all aspects of the body from blood vessels and nerves to muscles and organs.

NOTE: Ever prepared chicken – the white tissue that is clear when peeled back, THAT IS FASCIA!

Stephen Levin and John Sharkey have even suggested that bone is actually ossified fascia[i][ii]. Carla Stecco and Robert Schleip defined fascia using the term ‘fascial system’ which focuses on how fascia works rather than what it is,

“a network of interacting, interrelated, interdependent tissues forming a complex whole, all collaborating to perform a movement.”[iii]


Imagine wrapping your whole body in cling film, and then trying to walk. As you move forward, the cling film around the legs will move, however, the cling film as high as the neck and shoulders may be affected.

Because it wraps around everything in the body and can be found head to toe, scientists and physical therapists have termed this property ‘biotensegrity’ – without fascia, all the components of the body would find it difficult to maintain form, and instead, would at least be loosely connected and far from efficient. Therefore, biotensegrity refers to how the body maintains its integrity no matter the position or movement. This is discussed in greater depth later in this section.

“Biotensegrity refers to soft matter physics using terms such as compression and continuous self-stressing. It is a self-organising system that is not gravity dependent and also a stable yet fluid system that operates in a non-linear fashion.”[i]

Imagine throwing a tennis ball at the floor, the surface of the ball which makes contact with the surface is going to receive most of the pressure, however, the furthest part of the ball which makes contact with the surface will still receive pressure, just less so. That is like the human body as we move, thus, whilst the part of the body moved will absorb the most movement, the proximal structures will also absorb movement and depending on the severity of the movement will depend on where and how much the tissues will absorb the movement.

Susan Findlay, “What is Biotensegrity?”




The concept of how fascia works can be quite difficult to comprehend, so to help this understanding, a bit of physics is required regarding ‘tension vs strain’ and the Tensile Modulus, also known as the Young’s Modulus.


In 1660, British scientist Robert Hooke discovered the law of elasticity, and so the eponym was produced and called the law ‘Hooke’s Law’. Hooke found that material can deform under pressure, and this deformation is equal to the pressure applied, and upon releasing the applied pressure, the material returns to it’s original shape – Hooke’s Law, the law of elasticity.

Fast forward a few years to 1807 when British physician Thomas Young discovered how to measure the elastic qualities of materials, that when stretched or compressed, whether the material would withstand the pressure and spring back, permanently deform, or break. Therefore, this measurement, now known as the Young’s Modulus, measures how much stress, or strain, a material can absorb.


For those interested, the equation for Hooke’s Law is:

force = spring constant × extension


  • Force (F) is measured in newtons (N).

  • Spring constant (k) is measured in newtons per metre (N/m).

  • Extension (e), or increase in length, is measured in metres (m).


The equation for Young’s Modulus is:



  • Young’s modulus (E) is a property of the material that tells us how easily it can stretch and deform.

  • This is measured by the ratio of tensile stress (σ) to tensile strain (ε).

  • Stress is measured by the amount of force applied per unit area (σ = F/A), and strain measured by the extension per unit length (ε = dl/l).

  • Imagine a hair bobble, if you stretch it (stress), there will come a point in tensile strain where it will no longer return to its original length and place enough stretch (stress) on the bobble and it could break.

  • An inflated balloon is under constant uniform tension, and if you squeeze the balloon (applying compression, thus stress), it will create pressure in the rest of the balloon (tensile strain), but the overall tension in the balloon will remain the same. Apply enough compression (stress) to the balloon however, and the balloon will pop.

Apply this concept to the human body, you can stretch and compress soft tissue such as fascia, muscles and ligaments. An indivdual’s muscle condition and soft tissue composition will depend on how much pressure it can absorb before injury occurs such as tissue damage (e.g. strains, sprains, muscle tears) and deforming (e.g. bone break/fracture, tendon rupture, skin perforation, fascial tears). You can therefore apply the Young’s Modulus to the human body and Findley et al., (2012)[i] presented a respected narrative review on fascia, taking into consideration reputable research, and applied the Tensile Modulus, with factors such as the Young’s Modulus of a passive muscle stretch is 10 κPa whereas rubber is 20 κPa, demonstrating muscle is softer than rubber.

Now take this further and consider how your muscles, organs, blood vessels and nerves move together as one unit upon the skeleton, rather than flapping loosely, rubbing against each other and constantly feeling the pull of gravity as each part feels the pressure individually. Your fascia is everywhere throughout the body and enables you to move as one unit, constantly absorbing stress and strain whether it be sat at a desk for seven hours a day or completing an Ultra Marathon, and this is biotensegrity, Thus, your fascia absorbs stress in the form of pulls, stretches, compressions to ensure you move as one entire unit, how well it performs this depends on its integrity, hence the term biotensegrity, how well the body holds together both in parts and as a whole. Furthermore, some people are more genetically dense and tight, compared to some who are double jointed and hypermobile, meaning some people are more elastic than others, and research has found that manual therapy techniques, particularly when combined with strength and conditioning, help to promote healthy biotensegrity.

FOOD FOR THOUGHT: Ever since learning about fascia, Kim, the founder of this platform, has always wondered what the Honey Badger’s fascia is like. It is remarkably strong, yet it can turn freely within its own skin. However, as they are famously aggressive, Kim has not attempted to consider this any further and hopes that you do the same – it may be interesting but it’s not worth losing a limb over. Leave it to the professional researchers. Hence, food for thought…


There are different types of fascia for different purposes, yet all fascia predominantly consists of collagen[i], noting the density, composition and direction will depend on an individual’s ‘nature’ and ‘nurture’. This will be discussed further throughout the program as it is posture and biomechanics based on nature and nurture that can HELP determine soft tissue alignment, and thus the health of the soft tissue.


Chemoreceptors: A sensory cell or organ responsive to chemical stimuli.

Mechanoreceptors: A sensory cell or organ responsive to compression, tension, stretch and sound.

Fascia has 2 main properties:

  1. Reduce friction: Superficial fascia surrounds everything like cling film, from blood vessels to muscles, and can be found head to toe. By encasing everything, superficial fascia prevents many parts of the body from sticking to each other. Cowman et al., (2015) [ii] found that Hyaluronan cells (HA) which can be found in fascia, has lubricant properties due to its high-water content. Furthermore, Stecco discovered ‘fasciacytes’, a cell found in fascia that is dedicated to producing the “hyaluronan-rich extracellular matrix”[iii]. Such properties enable movement with cadence (smooth movement with both elasticity and stability). ‘Functional Fascia’i also state how superficial fascia, also known as ‘filmy fascia’ can “probably be classified as a loose aereolar connective tissue” which is a type of loose connective tissue that has no defined form, of which in Latin, ‘āreola’ means ‘small open space’.

   2. Proprioceptive organ: Proprioception is how the body monitors position and movement of joints and skeletal muscle to provide information             on the body in space. Thus, fascial proprioception absorbs and monitors pressures to enable the body to react most efficiently.

       Fascia contains four different types of sensory nerve endings which are collectively called Fascial Mechanoreceptors: Golgi Organs, Ruffini                 Receptors, Pacini Corpuscles, and Interstitial Receptors[iv].
