The aim of the present research was to investigate the effects of endurance continuous training (ECT), circuit resistance training (CRT), high intensity interval training (HIT) on fibrinogen and plasma viscosity in young obese men.

For this purpose, 44 young obese men voluntarily participated in the study, and randomly assigned into (CRT; n = 11), (ECT; n = 11), and (HIT; n = 11), and control group (Con; n = 11). ECT was done with 70% VO2max, while, HIT performed with 6 set of 3 minutes running at 90% of VO2max. Also, CRT was done at 11 stations with 20% 1RM, 3 times a week for 12 weeks. Blood samples were gathered before and after training protocols and fibrinogen and viscosity were measured in the plasma. To analyze the fibrinogen and viscosity, the blood samples were taken before and 72 hours after the last session of exercises.

The results showed that there is no significant difference between, HIT and CRT in the fibrinogen and viscosity after training (P > 0.05). However, the fibrinogen decreased significantly in the CRT (P = 0.001), HIT (P = 0.001) and ECT (P = 0.035) than control. Also, viscosity significantly decreased in the CRT (P = 0.001), HIT (P = 0.002) and ECT (P = 0.002) than control.

Finally, it can be said that none of continuous endurance, circuit resistance and high intensity interval training is preferable to improve plasma fibrinogen and viscosity. Although, they can reduce the levels of these indicators after 12 weeks.
