Your pain might not be a just loading or movement problem…
Over the last few years, research has been pointing in the same direction ⬇️
🧠 Tendons and pain can be influenced by your metabolic health, not just training volume.
Here’s what the science is telling us:
▶️ People with insulin resistance or metabolic syndrome have a higher risk of developing tendinopathy even when training exposure is similar.
▶️ Elevated blood sugar (HbA1c), even below diabetic levels, is linked to poorer tendon structure, reduced collagen quality, and slower walking speed.
▶️ Diabetes dramatically increases the risk of tendon pain and rupture, particularly in the Achilles and upper limb tendons.
▶️ High cholesterol and metabolic dysfunction are associated with higher tendon injury rates
▶️ Insulin resistance is linked to lower limb pain, suggesting pain isn’t always purely mechanical
▶️ Metabolic syndrome worsens rehab outcomes, meaning standard loading programs may be less effective if the internal environment isn’t addressed.
Translation:
You can be doing “all the right rehab exercises”…
…but if blood sugar control, lipids, sleep, stress, and recovery are off, your healing in a compromised environment.
This doesn’t mean loading doesn’t matter.
It means loading alone isn’t always enough.
Rehab should consider:
✔️ Progressive mechanical loading
✔️ Metabolic health
✔️ Sleep & recovery
✔️ Stress & systemic inflammation
Train the tissue, but don’t ignore the system it lives in.
