Summary
Middle-aged athletes show enhanced fibrinolytic activity after exercise, indicating improved vascular efficiency. Regular physical activity benefits the coagulation system, particularly in promoting fibrinolysis.
Area of Science:
- Sports Medicine
- Cardiovascular Physiology
- Hematology
Background:
- Middle-aged individuals increasingly engage in physical activity.
- The impact of intense exercise on the coagulation system in senior athletes requires further investigation.
Purpose of the Study:
- To investigate the effects of maximal exercise on coagulation and fibrinolysis in senior athletes.
- To compare the responses of trained athletes (rowers, marathon runners) with a control group.
Main Methods:
- Two groups of athletes (rowers, marathon runners, aged 41-60) and a control group (aged 40-71) underwent maximal exercise tests.
- Coagulation parameters including PT, PTT, fibrinogen, ATIII, PC, PS, F1+2, t-PA, and PAI were measured before and after exercise.
Main Results:
- Maximal exercise increased FBG, PT, and PTT in all groups, with a trend towards decreased PC and PS.
- Trained athletes showed significantly increased ATIII levels and higher t-PA with decreased PAI post-exercise compared to controls.
- The control group exhibited a moderate increase in F1+2.
Conclusions:
- Maximal exercise impacts coagulation and fibrinolysis parameters in middle-aged individuals.
- Trained athletes demonstrate enhanced fibrinolytic activity, suggesting a protective factor and greater vascular efficiency.
- Physical activity positively influences the coagulation system, especially fibrinolysis, in conditioned middle-aged individuals.
