The aim of this study was to determine the effect of eight weeks swimming training on Hepatic Enzymes and Hematological values in young female. Twenty-one healthy female were selected by convenience sampling method and were randomly assigned in the two groups: The test (n=15) and control (n=6) groups. The exercise protocol included long-term swimming training lasted for eight weeks and 3 sessions per week and every session lasted for 60 to 90 minutes with intensity of 65-85 percent of maximum heart rate reserve. Blood samples were taken to measure serum hepatic enzymes and hematological values before and after swimming training period. Data were analyzed by parametric (Paired and Independent-Samples t-test) and nonparametric (Wilcoxon and Mann-Whitney U test) for compared within and between groups; and the level of significance was set at P< 0.05. The level of WBC, RBC, Hb and Hct in exercise group towards the end of period of the training increased significantly. Also, there were no significant differences between groups in the levels of WBC, Hb, PLT, AST and ALT. The variance between group RBC and Hb were significant. Although, the levels of serum AST and ALT levels reduce at the end of the eight weeks swimming training, but these changes did not significantly. The liver function parameters, AST and ALT were decreased after eight weeks swimming training. These findings highlight the importance of imposing restrictions on swimming training and during clinical studies. Future examinations are now essential to clarify the effectiveness of exercise on various parameters.
