Is ApoB useful for Sport?

ApoB (apolipoprotein B) is a component of atherogenic lipoproteins (LDL, VLDL) and is considered a more accurate marker of cardiovascular risk than LDL cholesterol alone. In the context of sport, ApoB is mainly relevant indirectly: elevated ApoB may indicate increased atherosclerosis risk, which can impair long-term performance. However, direct studies linking ApoB to athletic performance optimization are lacking. Endurance athletes often have low ApoB levels, which is favorable. Strength athletes with high fat intake may have elevated levels, but the impact on performance is unclear. Evidence is based on epidemiological and mechanistic studies, not on randomized sport interventions. Thus, ApoB is useful as a health marker but not as a direct performance indicator. Caveat: single measurements are of limited value; long-term trends and the full lipid profile (including ApoA1, triglycerides) are more informative.
