Can HDL help with Sport?

The question of whether HDL (high-density lipoprotein) can enhance sports performance lacks strong scientific evidence. HDL is primarily known as 'good cholesterol' for its role in reverse cholesterol transport and cardiovascular protection. Some mechanistic research suggests HDL has anti-inflammatory and antioxidant properties that could theoretically aid muscle recovery and reduce exercise-induced oxidative stress. Additionally, HDL may influence mitochondrial function and fatty acid utilization, which are relevant for endurance athletes. However, no robust clinical trials directly link higher HDL levels to improved athletic performance. Observational studies show that physically active individuals often have higher HDL, but this is likely due to lifestyle factors (diet, exercise) rather than a causal performance benefit. Attempts to pharmacologically raise HDL (e.g., with niacin) have not improved outcomes and may carry risks. For athletes, focusing on overall lipid profile, cardiovascular fitness, and recovery strategies is more evidence-based than targeting HDL alone. MyBody-X DNA tests may report variants in HDL-related genes (e.g., CETP, LPL), but the sport-specific impact remains speculative. Evidence grade: mechanistic/mixed.
