Özet
Background: Nitric oxide (NO) is a gas with atherosclerosis-inhibiting effect. NO is also involved in the structure and function of erythrocytes (RBCs). Blood NO levels and haematological parameters (HPs) and the relationship between these parameters in swimmers over one-year training season have not yet been evaluated.\nMaterial and Methods: The effects of training (TP), detraining (DTP), and retraining period (RTP) on blood NOx (as total nitrite) levels and the relationships between NO and HPs in child swimmers were investigated. Ten trained male swimmers (11.1±0.6 years old) joined the study. With intervals of two months; blood biochemistry, physical and physiological measurements were performed after TP, DTP, and RTP. As an endurance criterion, critical speed (CS) was measured. Venous blood was obtained after 12 hours of fasting, serum iron, ferritin, total iron binding capacity, NOx (by Cd++ mediated 'Griess' assay) levels were measured, and haemograms were assessed.\nResults: NOx levels during TP were below the baseline levels (19.3%) and increased to the baseline during DTP. NOx was greater in RTP compared with DTP (p
