Hemostatic balance is a dynamic balance between the process of blood clotting and the mechanism of blood clot dissolution. The purpose of this endeavor was to investigate the effect of an 8-week selected aquatic aerobic training period on fibrinolytic indexes in retired athletes. 20 healthy male volunteers were randomly divided into experimental (n=10) and control groups (n=10).Both groups were similar regarding their age and body mass indexes. The training program for the experimental group included three weekly sessions of aquatic aerobic exercise for a period of eight weeks with an intensity of 55-70% of maximal heart rate. The control group had no participation in any regular training program. The blood samples were analyzed for t-PA and PAI-1 antigens, t-PA/PAI-1 complex and D-dimer. Independent and dependent t-tests were implemented to compare parameter averages at α=0.05.The results showed that in the experimental group, t-PA (P=0.001) and t-PA/PAI-1(P=0.003) levels increased significantly while there was a significant decrease in PAI-1(P=0.001) and D-dimer (P=0.001) levels. The comparison of the differences between the two groups showed that the changes in t-PA (P=0.022) and PAI-1(P=0.038) levels was significant. The results of this study showed that aquatic aerobic training can prevent thrombosis and sudden heart disease in retired athletes.
