摘要
Before and after a trial run for the selection of participants in a patrol-run competition, capillary blood samples of about 100 microliters were taken from the fingertips of 18 male participants from which pH, Mg++, Ca++ lactate and blood glucose were determined with a Phox - M analyzer of the NOVA Biomedical corporation. Comparatively low average Mg values before the trial run became even lower after the contest. A correlation of the individual Ca/Mg quotients in the blood before the run with the recorded running times afterwards showed a significant positive correlation, meaning that participants with low Ca/Mg quotients before the contest had the best chances for high scoring. This was underlined by a highly significant polynomial graph of the delta values of the quotient (Ca/Mg before Ca/Mg after contest), with a nadir close to the shortest running times. Similar to our findings at the occasion of a short but intensive obstacle run [1] it turned out, that those contestants with the least trial induced differences in their Ca/Mg turnover have the best chances for high scoring. Thus it seems possible, that either Mg or Ca/Mg quotient changes could be generally used as prognostic and diagnostic instruments in sportive contests.
