The effect of aerobic and weight lifting exercise on blood clotting

Aim: The purpose of this study was to examine the effect of an aerobic and weight lifting exercise program in blood clotting. Study design: Pre- post measurement after 15 min. and follow up measurement after two hours. Place and Duration of Study: Department of Physical.Education and Sport Science, Trikala Greece in April 2014. Methodology: The sample consisted of 15 undergraduate PE students (9 males M age = 21.56, SD =1.74, and 6 females M age = 21.33, SD =1.86) divided into two groups of 8 (7 males, 1 females) and 7 (5 males, 2 females) participants for the weight and aerobic training program respectively. Two key parameters were selected for measurement and analysis, that is, blood coagulation factor X and thrombin for all participants of both groups. Blood sampling equal to 5ml for each participant was performed prior exercise to verify normal levels of coagulation factors of each individual at rest, after the first 15 minutes of exercise and 2 hours after exercise. Results: Results showed that the average amount of factor Xa increased with each new donation while the average amount of thrombin decreased. Conclusion: A difference noted was that in the weightlifting training group reduction of thrombin occurred within the first 15΄ of training remaining stable thereafter, whereas in the aerobic training group reduction of thrombin continued even 2 hours after exercise. © JPES
