Abstract
Hypertension has become a public health problem nowadays due to its high rate of prevalence. Lifestyle modifications including exercise training is essential for the treatment of hypertension. However, based on the amount of restriction, intensity, and duration of exercise and recovery, aerobic exercise with and without blood flow restriction can lead to different changes in platelet counts and coagulation factors in hypertensive patients who are at high risk of blood coagulation and myocardial infarction. Therefore, the purpose of this study was to compare platelet counts, Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) following single bout aerobic exercise with and without blood flow restriction in hypertensive patients. Ten hypertensive men (state one) participated in this study as available sample. Participants completed an aerobic exercise with and without blood flow restriction in a cross-over randomized design. The exercise protocol consisted of 5 * 2-min walking bouts at 4 km/h, followed by 1-min inactive recovery. Blood samples were taken before, immediately, 30-min and 24-h after exercise. The results of this study showed that there was no significant difference in platelet counts, PT, and aPTT between two training conditions. However, exercise with blood flow restriction led to significant decrease in PT and aPTT 24-h post-exercise. Also, exercise without blood flow restriction led to significant decrease in aPTT 24-h pos-exercise. In summary, due to no significant difference in platelet counts, PT and aPTT between two conditions, it can be concluded that blood flow restriction exercise with monitoring coagulation factors at 24-h post-exercise is a safe training method for hypertensive patients.
