Abstract

Background: Regular exercise is generally associated with favourable alterations in risk from cardiovascular mortality and morbidity, but strenuous exercise has been implicated in the pathogenesis of sudden death. The mechanism behind this is not clear. One of the theory that explain about the mechanism is the concept of “General Adaptation Syndrome”(GAS). The concept listed severe muscular exercise incorporates the adrenosympathetic emergency response which due to activation of the coagulation cascade. Objectives: To review the effects of short term exercise on whole blood clotting time.. Subject and Method: The study was a quasi experimental study with the pretest-posttest design. Subjects were 20 male person, 18-23 years old, with minimal height 165 cm. The exercise that employed was the 3 minute Harvard Step. Blood samples were obtained at rest and immediately after Harvard Step. Statistic test were performed by Shapiro-Wilk test, Paired t-test. Results: Exercise results in activation of the coagulation cascades, as shown by a reduction in whole blood clotting time average. The averages are 240,2 seconds (before) and 201,4 (after). The result of paired t-test showed that there were significant differences (p<0.05). Conclusion: There is a reduction in whole blood clotting time average which considered significant. Keywords: whole blood clotting time, exercises, Harvard Step
