The Claim
Chronic low-grade systemic inflammation, termed 'inflammaging,' is associated with progressive declines in mobility, muscle mass, and joint function in older adults, as evidenced by elevated levels of pro-inflammatory cytokines such as IL-6, TNF-α, and CRP correlating with reduced gait speed, sarcopenia, and osteoarthritis severity.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults, persistent low-level inflammation is linked to worsening mobility, loss of muscle mass, and increased joint damage, as measured by higher levels of specific inflammatory markers in the blood.

As people age, damaged cells accumulate and release inflammatory signals that spread to nearby cells, causing more cells to become damaged and stop working. These signals also prevent muscles from repairing themselves, weaken the blood vessels that feed muscles, and make joints and nerves hurt more. The body's cleanup system becomes slower, so dead and broken cells pile up, keeping the inflammation going. This cycle reduces muscle strength, makes walking harder, and causes joint pain and stiffness.
What the research says
1 studyOlder people with more body inflammation tend to walk slower and lose muscle strength, and when doctors reduce that inflammation with drugs or healthy habits, people can walk farther. This shows inflammation is linked to moving less as we age.
