Introduction
Changes and imbalances in the homeostasis system is one of the main causes of heart attacks. Conflicting data existed about the effect of specific exercises on these factors. Therefore, the purpose of this study was to compare the effect of 4 weeks of resistance training and aerobic exercises on blood coagulation and fibrinolytics factors in inactive older men.
Materials and Methods
A total of 30 elderly people (age 63/73 ± 2/66 years) were randomly divided into 3 groups: an aerobic (n=10), resistance (n=10) and control (n =10) groups. Respectively, aerobic and resistance groups, participated in a program of aerobic and resistance exercise (3 days a week for 4 weeks). Body weight, bmi and coagulation factors levels such as, fibrinogen, pt, ptt and platelet count and also d-dimer fibrinolytic factors were measured.
Results
Overall 4 weeks of aerobic exercise training in older individuals significantly reduced fibrinogen, pt, ptt and platelets count levels, whereas increased d-dimer levels.
Also 4 weeks of resistance training significantly reduced fibrinogen, pt, ptt and platelets count levels, but increased d-dimer fibrinolytic factor. It was also found that the effect of resistance training on blood coagulation factors such as pt, ptt, platelet count and d-dimer fibrinolytic factors was more than aerobic training, but the effect of aerobic training on coagulation factor fibrinogen was higher than resistance training.
Conclusion
This study suggested that participation in aerobic and resistance activities can be very useful for prevention of threatening complications of hemostatic system and the aging process.
