The Claim

In rats undergoing low-frequency resistance training, tumor necrosis factor-alpha (TNF-α) protein expression in the soleus muscle is 24% lower than in sedentary controls.

In plain English

Rats that performed low-frequency resistance training had 24% less TNF-α protein in their soleus muscle compared to rats that did not exercise.

See the scientific wording

In rats undergoing low-frequency resistance training, tumor necrosis factor-alpha (TNF-α) protein expression in the soleus muscle is associated with a 24% reduction compared to sedentary controls, suggesting a potential link between this training protocol and reduced inflammatory signaling in muscle tissue.

Why this might work

When muscles are gently pulled during light weight training, the force activates signals inside muscle cells that make them grow bigger. As the muscle grows, it stops producing a protein called TNF-α that causes inflammation. This happens without any damage or stress to the muscle.

    Rats that did light weight training once or twice a week had 24% less of a body inflammation marker in their leg muscle than rats that didn't exercise — so this kind of exercise may help reduce muscle inflammation.
