BACKGROUND: The present study aimed to differentiate the acute effects of aerobic, resistance and concurrent exercises, and 40-m maximal shuttle run test (MSRT) on coagulation and fibrinolysis in non-athletic healthy young men.
METHODS: Fifty participants (20-30 years old) were randomly divided into a control and four exercise groups; Aerobic, Resistance, Concurrent, MSRT (each n=10). Single session of exercise was performed in Aerobic group using cycle ergometer (60% heart rate max) for 40 min, Resistance group using 3movements for upper extremity and 3movements for lower extremity with 60% of 1-Repetition Maximum (each movement in 2sets with 8-10repetitions), Concurrent group by combination of aerobic and resistance protocols, and the MSRT group using four trials of the 40-m MSRT. The duration for aerobic, resistance and concurrent exercises was 60min and for MSRT was 30min. Before and 30 min after exercise, blood samples were obtained for evaluation of fibrinogen (mg/dl), D-dimer (mg/dl), prothrombin time (PT), partial thromboplastin time (PTT) and platelet count (×1000/μl).
RESULTS: There was a significant reduction in fibrinogen of exercise groups compared to before exercise (P<0.01) and control group (P<0.05). D-dimer, as the index of fibrinolysis, was significantly increased in exercise groups compared to before exercise (P<0.01) and control group (P<0.05). Aerobic exercise and MSRT also increased the PT and PTT (P<0.001). Finally, the number of platelets had a significant reduction following resistance and concurrent exercise protocols (P<0.001, P<0.01).
CONCLUSION: Based on our findings, both coagulation and fibrinolytic activity are acutely affected by single session of different exercise protocols.
