Regular physical activity significantly lowers cardiovascular disease risk by influencing blood clotting factors like fibrinogen. Exercise impacts both hemostasis and fibrinolysis, crucial for preventing heart events.

Area of Science:

  • Cardiovascular Physiology
  • Hemostasis and Thrombosis
  • Exercise Science

Background:

  • Long-term physical activity reduces cardiovascular morbidity and mortality.
  • Hemostatic and fibrinolytic systems are key mediators of exercise's cardiovascular benefits.
  • Fibrinogen, factor VII, PAI-1, and tissue-plasminogen activator are critical cardiovascular risk factors.

Purpose of the Study:

  • To investigate the relationship between physical activity and cardiovascular risk factors, particularly fibrinogen and fibrinolytic markers.
  • To synthesize existing research on exercise's effects on hemostasis and fibrinolysis.
  • To assess the implications for cardiovascular event prevention.

Main Methods:

  • Review of randomized controlled trials, intervention studies, and population-based cross-sectional studies.

  • Analysis of data on plasma fibrinogen levels in relation to sport and leisure activity.
  • Examination of studies on endurance exercise effects on fibrinolytic system markers.

    • Main Results:

    • Consistent inverse relationship found between physical activity and plasma fibrinogen levels.
    • Exercise significantly impacts fibrinogen, potentially reducing coronary event risk.
    • Data on endurance exercise effects on fibrinolysis are inconsistent; acute exercise transiently activates coagulation and fibrinolysis in healthy individuals.

    Conclusions:

    • Regular physical activity, especially impacting fibrinogen, offers substantial cardiovascular protection.
    • Individuals with ischemic heart disease may face risks from unaccustomed strenuous exercise due to impaired fibrinolytic response.
    • Further research is needed on exercise's specific effects on the fibrinolytic system.
