Part 1: Muscle
Inspired by one of Andrew Taylor Still’s guiding principles — that the body has the capacity to regulate and heal itself when properly supported.
One of the most powerful systems in your body isn’t a drug or a treatment — it’s your muscle.
We often think of muscle as something that helps us move. But in reality, it plays a central role in how the body functions, adapts and maintains health over time.
Movement and load (biomechanics)
Muscle is what allows the body to absorb and distribute load. Every time you bend, lift, walk or sit, your muscles are working to:
control movement
stabilise joints
share forces across the body
When this system is working well, movement feels efficient and relatively effortless. When it isn’t, load gets concentrated in certain areas — often the spine, neck or joints — which is where pain tends to develop.
This is something we see daily in practice. It’s rarely just “damage” — more often a question of how well the body is managing load.
Muscle as a metabolic organ
Muscle is one of the primary sites where your body handles glucose.
After you eat, glucose enters the bloodstream. Muscle tissue helps clear this by taking glucose into the cell, where it can be stored as glycogen or used for energy.
This process is influenced by both:
insulin (after meals)
and muscle contraction itself (movement and activity)
In other words:
– the more active and functional your muscle is, the better your body becomes at regulating blood sugar.
When muscle mass and activity decline, this system becomes less efficient. Blood sugar control worsens, and low-grade inflammation can increase — both of which are linked to a range of long-term health conditions – and pain.
Inflammation and resilience
Muscle also produces signalling molecules (often called myokines) during contraction.
These help:
regulate inflammation
support immune function
influence how other tissues behave
So movement isn’t just mechanical — it’s biochemical.
It’s one of the ways the body maintains balance internally.
The nervous system connection
Muscle is in constant communication with the nervous system.
Specialised receptors within muscle provide the brain with information about:
position
movement
tension
This is known as proprioception — your body’s awareness of itself.
When this system is working well:
movement is coordinated
balance improves
effort feels lower
When it’s disrupted:
movement becomes less efficient
the body feels less predictable
pain sensitivity can increase
Restoring this connection is often a key part of recovery.
Muscle, ageing and brain health
From around our mid-40s, we begin to lose muscle mass — a process known as sarcopenia. This isn’t just about strength.
Reduced muscle mass is associated with:
decreased metabolic efficiency
increased risk of falls
reduced independence
There is also growing evidence linking muscle health with brain health.
Regular muscle activity appears to support:
blood flow to the brain
neurochemical balance
cognitive resilience
Which is why maintaining muscle is increasingly associated with a lower risk of cognitive decline and dementia.
What we see in practice
When muscle function improves, the changes are often broader than expected.
People don’t just feel “stronger” they:
move more confidently
experience less pain
tolerate daily life better
Sometimes it’s the difference between:
avoiding movement
and trusting the body again
Muscle, resilience and long-term health
Muscle mass is increasingly recognised as a strong predictor of overall health and longevity. Research consistently shows that individuals with higher levels of muscle mass and strength tend to have lower rates of illness and reduced risk of what’s known as all-cause mortality — in simple terms, a lower likelihood of dying from a wide range of conditions.
Part of this comes down to how muscle supports the immune system and the body’s ability to cope with stress. Well-functioning muscle helps regulate inflammation, supports metabolic stability and provides a reserve that the body can draw on during periods of illness or recovery.
In real terms, this isn’t about extremes or athletic performance. It’s about having enough physical capacity to cope with everyday life, to recover more effectively when things go wrong, and to maintain independence over time.
How we can help
At our clinic, we look at how your body is functioning as a whole. Through osteopathy and physiotherapy, we aim to:
improve how muscles and joints work together
reduce unnecessary strain
restore movement efficiency
guide you with appropriate, realistic exercise
This isn’t about pushing harder. It’s about helping your body work better.
The takeaway
Muscle is not just about strength. It is part of your body’s internal system for:
regulating energy
managing inflammation
supporting movement
maintaining long-term health
In many ways, it truly is part of your medicine cabinet.
If you’re unsure where to start, we can guide you with a plan tailored to you.
