- Abstract:
- To investigate the impact of mental excitement on metabolism we collected pH, pCO(2), pO(2), and ionized Mg values out of capillary blood of 192 cadets, won during the expectation phase before a running trial, important for their military officer career. Mostly by linear correlation analyses, we could show that probable higher catecholamine levels, not uncommon in sympathoadrenal anticipation, seem to ultimately provoke increased oxygen binding in blood as well as (temporary) Mg increase in blood as a consequence of Mg loss from tissues. Both processes, O-2 retention in blood and Mg loss from tissues contribute to impaired workload resistance of the metabolism.
