Objective: Interleukin-6 (IL-6) is an effective and functional protein with a cytokine structure. IL-6 is effective in the immune system like a pro/anti-inflammatory response, and muscle tissue hypertrophy and repair. Our study aimed to investigate the IL-6 rs1800795 polymorphism distribution in Turkish National Cross-Country Skiing Athletes and to determine the advantageous genotype for endurance performance. Methods: 34 athletes within 3 groups; General (Group-1), Women (Group-2), and Men (Group-3) were enrolled to the study. Also each groups were divided into sub-groups according to their “1-kilometer cross-country average skiing-times (1 km-CCSTAs)”. Blood samples were used for DNA isolation and genotyping were completed by real time- PCR. Results: The groups' 1 km-CCSTAs were 188.7 ± 22.4, 212.3 ± 17.8, and 177.4 ± 14.1 seconds, respectively. We detected the genotypes as 17 GG (50%) and 17 GC (50%) in Group-1; 5 GG (45%) and 6 GC (55%) in Group-2; 12 GG (52%) and 11 GC (48%) in Group- 3. We detected no CC genotype in groups. Chi-square Fisher’s test was used for statistical analysis. Conclusion: An increased GC genotype ratio was detected in the faster sub-groups of each group compared to the slower sub-groups. But we obtained the significant genotype distribution only in Group-3 (p
