title: Decreased prostacyclin sensitivity of human platelets after jogging and squash.
abstract: 8 healthy male volunteers performed jogging (as an example of an aerobic metabolic condition) and squash (as an example of an intermittently anaerobic metabolic condition). The platelets sensitivity to prostacyclin (PGI2) decreased after jogging. After squash, a statistically significant (p 0,001) decrease in the sensitivity of the platelets could be seen. Our findings suggest that an early alteration of platelet sensitivity might play a key role in maintaining the hemostatic balance and could be of greater importance than the vascular wall PGI2-synthesis, as the sensitivity changes immediately, whereas the PGI2-formation change is a long-term process.
