“…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 tumover 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.…”

Before and after a trial mn for the selection of participants in a patrolrun 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 Biomédical 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 tumover 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.

“…One gets the impression, that patients suffering ñ"om hypertonia together with higher blood glucose levels are also subject to higher metabolic turnover, indicated by higher Mg and K output from tissue. The diminishing K and Mg levels [4,5,12,16] in the higher glucose group of the normotonics could indicate that -contrary to hypertonics -clearance from the blood is still faster than input from tissues.…”

Out of 100 microliters of capillary blood of 32 normotonic and 55 hypertonic (RR at least 140/100) diabetic patients, the following parameters were determined at 09:00 a.m.: pH, pCOz, baseexcess, HCO3, PO2,02sat., Na, Ca, Mg, K, lactate and blood glucose. Group averages of the normotonic and hypertonic patients did not show any significant differences in the parameters mentioned. But when we split the 2 groups along their glueose averages, forming 4 subgroups with higher and lower glueose levels, significant differences between Mg and K in the respective groups were evident, pointing towards an increase in electrolyte metabolism due to both hyperglyeemia and hypertonia. Linear regressions between Mg, glueose and pH within the four groups inereased eircumstantial evidenee for our supposition of increased electrolyte metabolism being attributable to both hyperglyeemia and hypertonia, considerably. It turned out that high blood glucose alone already increases electrolyte metabolism, shown by positive correlations with Mg and glucose and negative correlations between Mg and pH which culminates in the highest Mg values along with highest glueose and lowest pH values in patients with eombined hyperglyeemia and hypertonia. Although we partly drew similar conclusions in a fonner paper [14], the step forward in the present work is that results won by eomparison of parameter changing (delta values) between two sampling events can be confirmed by using the directly determined data of just a single sample. Thus, appropriately processed data and eomparatively simple mathematical operations like implementation of linear regressions do not only detect significant differenees hidden behind similar group averages, but also con-siderably curtail the necessary diagnostie blood sampling.

“…One of the most important functions of Mg is the transport of energy to the muscles and to the brain. A lack of Mg reduces performance automatically [4], [5]. Because of the lack of Mg in the daily meals, a daily its substitution of about 300 milligrams is recommended to reach an average performance [6].…”
