Evidence check: CRP Entzündung in the context of Sport

CRP (C-reactive protein) is a non-specific inflammation marker with a dual role in sport: acute exercise (e.g., intense strength training) can transiently raise CRP as part of normal muscle repair, while regular endurance training lowers baseline inflammation and cardiovascular risk. Genetics can modulate these effects: the APOA2 rs5082 polymorphism (CC genotype) is associated with higher CRP when saturated fat intake is high (>22 g/day). This may be relevant for athletes on high-fat diets. However, the evidence is moderate – mostly observational, with few RCTs. MyBody-X tests include hsCRP, but a single measurement is not diagnostic. Chronically elevated CRP warrants medical evaluation. The interplay of exercise, diet, and genetics is complex and individual; blanket recommendations are not justified.
