- Abstract:
- About 100 mu L of capillary blood of 22 officer trainees of the Theresan Military Academy in Wiener Neustadt, Austria, have been analyzed before and after a 2,400 m run for ionized magnesium, pH, pCO(2), pO(2), and lactate. The investigated group was divided into two subgroups. One of them comprised 10 persons with ionized Mg values of 0.5 mM and below. The other with higher Mg levels. Although the mean values of pH, pCO(2), pO(2), and lactate of the two subgroups were not significantly different, correlative analyses between the parameters before and after the run showed significantly less CO2 loss, less alkaline blood, and therefore less O-2 binding and lower lactate levels before the run. After the run ionized Mg values of the groups are no more different, however, correlative pCO(2) loss with changing pH stabilizes pH in the high Mg group significantly. We concluded that low Mg before the run is due to fatigue in the past, but that even acute Mg supplementation may be effective. An inability of Mg increase during mental anticipation reactions seems to strongly indicate Mg deficiency with significant metabolic shortcomings.
