The present study examined the effects of progressive exercise (pyramidal) short-term program on plasma fibrinogen, lipid profile and blood viscosity in untrained young men. Changes and imbalances in homeostasis lead to cause of heart attacks. There is conflicting information about the effect of exercise on these factors. 19 young healthy untrained men were randomly assigned to the exercise group (n = 10) and controls (n = 9) groups. Exercise training group with increasing severity of heart maximum 25 to 100 percent began to run the practice (pyramid) in 42-minute sessions, 3 times a week, for 4 weeks. There was no significant difference between the parameters of body composition, control, and training groups. Levels of total cholesterol and low density lipoprotein density and viscosity of the blood significantly decreased in the training group compared with the control group (p value, respectively is 0.001, 0.001 and 0.035). The changes in the concentration of fibrinogen, high-density lipoprotein and triglycerides in both groups are not significant in both groups (p value, respectively is 0.645, 0.993 and 0.421). The present results show that it is possible that progressive training (pyramidal) short-term program changed the levels of cardiovascular risk factors by reducing blood viscosity.
