Effect of One Period of Resistance Training on Some Fibrinolytic Factors of Active Young Men

Aims: Fluctuation in the homeostasis system is one of the main causes of heart attacks. Physical activity plays an important role in automatic control of the cardiovascular system. This study aimed at investigating the effect of one period of resistance training on some fibrinolytic factors in active young men.
In this semi-experimental study, 30 young male athletes belonging to a gym in Qom, Iran were selected through convenience sampling method in 2016; they were randomly assigned to single-joint resistance training, multi-joint resistance training, and control groups (N=10). The training protocol was implemented 3 sessions per week for 8 weeks. In order to evaluate the serum levels of fibrinogen, PT (Prothrombin Time), and PTT (Partial Thromboplastin Time), 6cc blood sample was collected from participants before training and after the last training session. The data were analyzed by SPSS 20, using factor analysis of variance (2×3), Bonferroni's post hoc test, and paired t-test.
Findings: Regardless of the type of protocol, a resistance training period reduced fibrinogen (p=0.0001) and increased prothrombin time (p=0.047), but it did not significantly change partial thromboplastin time (p=0.111).
Resistance training reduces the fibrinogen amount and increases PT in active young men, but it does not change PTT.
