The Claim

Aerobic training significantly reduces interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) levels in adults with chronic kidney disease, with standardized mean differences of −0.34 and −0.62 respectively, and has no significant effect on interleukin-10 (IL-10) or C-reactive protein (CRP) levels.

In plain English

In adults with chronic kidney disease, aerobic exercise lowers levels of interleukin-6 and tumor necrosis factor-alpha, but does not change levels of interleukin-10 or C-reactive protein.

See the scientific wording

Aerobic training significantly reduces interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in adults with chronic kidney disease, with effect sizes of SMD −0.34 and −0.62 respectively, but does not significantly affect interleukin-10 (IL-10) or C-reactive protein (CRP), indicating a more limited anti-inflammatory profile compared to resistance training.

Why this might work

Aerobic exercise improves blood flow and muscle activity, which helps remove harmful waste products from the blood that build up in kidney disease. These waste products normally trigger immune cells to release inflammatory chemicals. When they are cleared, immune cells become less active and stop producing as much IL-6 and TNF-α. At the same time, aerobic exercise reduces fat around organs and inside muscles, which also stops fat tissue from releasing more inflammatory signals. This lowers the overall level of inflammation without affecting IL-10 or CRP.

    In people with kidney disease, walking or cycling lowers two harmful inflammatory chemicals (IL-6 and TNF-α) but doesn’t change the protective one (IL-10) or CRP — just like the claim says. Strength training works even better, which the study also confirms.
