Objective: to synthesize evidence on the effects of aerobic training (AT) on C-reactive protein (CRP) levels in healthy older adults. Method: this is an integrative review with searches conducted in the PubMed/MEDLINE, Scopus, Embase, Web of Science, and LILACS databases. Results: a total of 1,388 records were identified, and 119 were excluded due to duplication. In the end, six studies were included, most of them randomized clinical trials, conducted in South Korea, Portugal, Japan, the United States, and New Zealand, totaling 390 participants (156 men and 234 women). All studies reported reductions in CRP following AT, although only 67% showed a statistically significant effect. Longer (≥16 weeks) and progressive interventions were more effective, especially among individuals with elevated baseline inflammation. Body composition did not consistently explain the observed reductions. Conclusion: AT reduces CRP levels in older adults, particularly in long-term programs and among participants with high CRP, reinforcing its role in attenuating aging-related inflammation.
