Twenty-five men and 26 women were studied to investigate the effects of acute strenuous exercise on hemostasis after obtaining their informed consent. After familiarization, they performed exercise on a bicycle ergometer at 75% of their predetermined maximal workload until exhaustion. Bleeding time, measured by the Simplate method, and venous blood cell counts of platelets (Plt), erythrocytes (RBC), leukocytes (WBC) were determined at rest and immediately after exercise. We found that bleeding time of Chinese in our study was longer than those of the westerners in other studies and that bleeding time was significantly shortened after exercise from 8.3 +/- .7 to 6.5 +/- .5 min in men and from 11.4 +/- .9 to 8.6 +/- .8 min in women (p less than 0.001). In men, but not in women, acute exercise also augmented the initial bleeding rate and bleeding amount from standard incisions. We also observed that RBC, WBC and Plt counts were greatly increased. The increased percentages for RBC, WBC and Plt in men were 7 +/- 1%, 59 +/- 7%, 16 +/- 3%, and those in women were 5 +/- 1%, 42 +/- 6% and 17 +/- 2% respectively.
