What is Fascia?
Fascia is essentially the connective tissue matrix that runs throughout the entire body. It encases, cushions, protects, and provides structure as part of your body’s fascial network. The importance of fascia cannot be overstated. It’s crucial for physical movements, plays a key role in the musculoskeletal system, and influences function and optimum coordination of our muscles through myofascial connections. It’s a part of a body-wide fascial web that maintains structural integrity.
The fascial system is diverse and found throughout the body. While incredibly varied depending on its function and location, types include:
- Muscular fascia
- Visceral fascia (found in the intestines)
- Tendons, ligaments, muscle fascia, and joint capsules
Anatomical diagrams show superficial fascia and deep fascial layers beneath the skin. Fascia also surrounds organs as organ fascia.
The Layers of Fascia
The exact structure varies, but fascia always consists of the same core building blocks in different proportions. It has a layered structure, such as:
- Fascial sheaths around muscles
- Layers in the fascial planes of the abdominal net
- The large thoracolumbar fascia, which is made up of three different layers forming a crucial myofascial junction
Fascia is primarily made up of the core building blocks of any living organism: protein and water. Specifically, it always includes:
- Collagen
- Elastin
- A watery to gel-like ground substance (extracellular matrix)
Collagens are major components, serving as scaffold or structural proteins that help give the body its shape through fascial tensegrity.
Fascia encases individual muscle fibers with razor-thin sheaths (endomysium), surrounds fiber bundles (perimysium), and forms the outermost muscle sheath (epimysium). Muscles would not be able to function or keep their shape without their fascial sheaths.
The fascial continuum includes:
- Tendons – which transfer energy from muscle to bone
- Ligaments – which connect bones
- Nerves and blood vessels – which run inside fascial tissue layers
This interconnectedness forms a dynamic tensional network with bones.
Recognizing Fascia Pain and Dysfunction
Fascial tissue, especially in the back, is densely populated with pain sensors. Problems in the fascial tissue can contribute to or even cause pain through myofascial trigger points and fascial restrictions. Patients often describe deep back pain originating in the fascia as “nasty” or “horrible”. Muscle soreness is now understood to be mainly due to the fascia that surrounds the muscle, often manifesting as myofascial pain syndrome.
Many common complaints are linked to the condition of connective tissue:
- Chronic back pain
- Shoulder and elbow problems
- Neck pain
- Plantar fasciitis
- Adhesive capsulitis (frozen shoulder)
- Heel spurs
When fascia becomes matted or develops fascial adhesions, it restricts muscle function and energy transfer, making movements less fluid and increasing stiffness. This reduced elasticity makes us stiff. Fascial densification is also associated with aging. Lack of exercise leads to fascia becoming matted and losing its fascial hydration.
Maintaining Healthy Fascia
Targeted and regular fascia training can sustainably change fascial tissue, improving its elastic properties through fascial fitness techniques. Fascial movement in everyday life is important.
Effective approaches include:
- Manual therapy methods like massage and pressure applications stimulate fascia through myofascial release
- Mindful breathing is beneficial for training through improved fascial elasticity
- Varying movement is key to maintaining fascial flexibility
Effective training includes diverse stimuli:
- Elastic suspension movements
- Stretching
- Soft steady stimulation
- Sensory impulses
- Mechanical pressure
Pressure or rolling out fascia encourages fluid exchange through fascial hydration techniques. Manual methods like Structural Integration (Rolfing), myofascial release, and osteopathic grips use these effects to restore fascial glide.
For overall fascial health and preserving optimal fascial architecture:
- Maintain a healthy weight
- Don’t smoke
- Stay hydrated
- Get enough protein and Vitamin C
- Get enough sleep
Breaking Up and Improving Fascia
Pressure applied through self-massage, trigger point treatment, or rolling with tools like foam rollers squeezes out the fascia like a sponge. This helps release tension and alleviate pain and soreness. Varied movement and tensile force promote resilience and elastic storage capacity. Short, cyclic, quickly repeated motions are effective for training elastic explosiveness.
Manual therapy and physiotherapy methods can apply pressure and sliding techniques to release tension and adhesions. If you have connective tissue disorders or experience frequent pain and injuries, it’s advisable to see a specialist before starting training.
Exercises that involve rolling out areas like the back, thighs, or feet with a roller or ball promote fluid exchange and regeneration. These practices can be part of a daily routine for regeneration.
Rehydrating Your Fascia
Water is crucial for cellular metabolism in connective tissue. Hyaluronan is a substance in the matrix responsible for its water content and can change from a thick gel to a watery lubricant.
While staying hydrated is important, simply drinking water isn’t enough. The tissue needs to be squeezed like a sponge through movement or pressure to absorb fresh fluid. Regularly making your tissue “thirsty” through exercise helps it absorb the necessary water.
A healthy lifestyle with nutritious food and enough sleep is essential for the maintenance of the whole body, including fascia.
The matrix hosts immune cells and nerve endings. Fluid exchange:
- Removes harmful metabolic waste products (sometimes including inflammatory neurotransmitters)
- Draws in clean, fresh fluid from blood plasma
- Stimulates metabolism
- Improves the supply to fascia and associated organs
Certain nutrients like protein and Vitamin C are important for collagen synthesis. Avoiding being overweight helps prevent inflammation in the body, which can damage fascia.
Understanding fascia is truly a journey into the structures that literally make us who we are. Taking care of your fascial system through movement, targeted exercises, and a healthy lifestyle is key to staying energetic, elastic, and dynamic.
