Abstract
Introduction and purpose: Examining the hormonal profile of different sports fields is used in many researches to provide criteria and indicators. Considering the importance of cycling, this study examined the hormonal profile of male cyclists of the Iranian national team.
Materials and methods: In this descriptive study, 95 male cyclists of the Iranian national team with a mean and standard deviation of height 175.4±4.5 cm, weight 74.5±3.8 kg and body mass index 9.0±0.7 23 were examined as samples. The research variables included serum levels of testosterone, growth hormone, insulin-like growth hormone, luteinizing hormone, thyroid-stimulating hormone, and erythropoietin hormone. 48 hours after the last training session, fasting blood was taken from the elbow vein of the subjects.
Results: In male cyclists of the Iranian national team, the average serum level of testosterone hormone was 4.44±0.23 ng/ml, the average serum level of growth hormone was 0.24±0.17 ng/ml, the average serum level Insulin-like growth hormone 246.3±56.64 μg/L, luteinizing hormone mean serum level 2.44±0.72 IU/mL, thyroid stimulating hormone mean serum level 2.33±0.8 mIU/mL and the average serum level of erythropoietin hormone was 4.79 ± 0.97 mIU/mL.
Discussion and Conclusion: The reference values of the examined hormones are not valid for the general population of elite athletes. New reference limits should be established for hormonal variables in elite athletes. Because their metabolic, nutritional and exercise status is different from the normal non-athlete population.
