The effect of 12 resistance training sessions on some coagulation and fibrinolytic factors in non-active men

Blood coagulation is one of the most important physiological factors in the body,s homeostasis imbalance. There are some conflicting data about the effect of exercise trainings, especially resistance training on this factor. Hence, the aim of the present study was to identify the effect of 12 sessions of resistance training on some coagulation and fibrinolytic factors in non-active men. Towenty subjects volounteered for this semi experimental study and randomly divided into two groups including experimental (n=10) and control (n=10) groups. The resistance training protocole included 6 movements such as chest press with halter, lat pull, triceps with halter, squat, extension and flexion of the knee which performed in 12 sessions up to 60-40 percent of one repetition maximum. Blood samples were obtained at baseline and at the end of the study. To make intra and inter-group comparisons, analysis of variance with repeated measures and LSD tests were appllied and for all statistical analysis, the significance level was set at p<0.05. The results showed that although the levels of fibrinogen reduced and the D-dimer increased after resistance training protocole, these changes were not statistically significant. Moreover, the number of platelets in both groups did not show a significant changes (p>0.05). As well as, prothrombin time and partial thromboplastin time factors increased significantly in resistance training group (p=0.02 and p=0.01 respectively). 12 sessions of resistance training via the reducing of levels of fibrinogen and increasing the prothrombin time and partial thromboplastin time could prevent thrombosis and sudden incidence of heart disease in non-active young men.
