Elevated homocysteine (HCY), asymmetric dimethylarginine (ADMA), Neopterin (NP) and oxidative stress have been established as risk factors for vascular disease and coronary artery disease. The purpose of the study was (a) to assess the HCY, ADMA, NP, malondialdehyde (MDA) and glutathione (GSH) levels and (b) to determine the relationship between these parameters in wrestlers, track and field athletes, and non-athletes. 35 subjects in total, comprising of 15 wrestlers (x¯ = 17.6 ± 2.3 years), 10 track and field athletes (x¯ = 16.6 ± 2.2 years) and 10 non-athletes (x¯ = 17.2 ± 0.8 years) voluntarily participated in the study. The HCY, ADMA, NP, MDA, GSH levels as in subjects' blood was performed through the antecubital vein in the morning while in the pre-prandial state. There was a significant difference in ADMA, MDA, GSH concentrations between in track and field athletes and wrestlers. There was a significant difference in HCY, NP concentrations between wrestlers and non-athletes. There was a significant difference in HCY, MDA concentrations between track and field athletes and non-athletes (p< 0.05). The HCY and NP showed high level correlation in all groups (track and field athletes; r = .952; wrestlers; r = .886; non-athletes; r = .900; p< 0.01). The GSH and NP showed high level negative correlation in non-athletes (r = - .900; p< 0.01). According to the results of HCY, ADMA, NP, MDA, the lowest level was found in athletes and the highest appeared in the non-athletes. In conclusion, we think that regular training may have positive effects on cardiovascular and anti antioxidant level.
