Abstract (2. Language): 
This study was performed to determine stress hormone levels and association with immune parameters. Eleven elite basketball players (who mean age of 21.45±1.63 years) and ten elite cyclists (who mean age of 20.00±1.49 years) volunteered for study. Peripheral venous blood samples were drawn at rest during the pre-competition period. Total erythrocyte, leukocyte numbers, Hb and Hematocrit were performed with coulter hematology analyzer. Determination of lymphocyte subpopulations (CD3+, CD4+, CD19+, CD45+) was performed by flowcytometry. Growth hormone and cortisol concentrations were determined by radioimmunoassay kits. Significance of changes in leukocyte subsets and stress hormones were analysed by using Mann Whitney U test. Assosiations between cell counts and hormone levels were analysed by using Spearman’s correlation analysis. In professional basketball players Hb and Hct values were higher than the cyclists. Total leukocyte number and granulocyte rate were high in the basketball players and lymphocyte and monocyte rate were high in the cyclists. Growth hormone and cortisol levels were high in the cyclists. CD4+ Thelper/inducer cell numbers were significantly high in the basketball players although CD19+ B cells numbers were high in the cyclists. There were no significant differences in CD3+ total T cells numbers in two groups.
