Abstract

Lactate and Mg⁺⁺ were determined from the blood of 14 probands before and after an exhausting military steeplechase of about 3-5 minutes’ duration. It turned out, that Mg⁺⁺ changes not only correlated with lactate changes in a highly significant manner, but also with the running times and the awarded scores in a polynomial curve, so, that subjects with the smallest deviation of blood Mg⁺⁺ had the highest chances of scoring high with shortest running times. Outstanding Mg⁺⁺ increase or decrease during this exhaustive exercise seems to depend largely upon the effort needed to overcome the distance. By pooling information about lactate- and Mg⁺⁺ interaction it also became possible to discern low scorers with high efforts and low scorers with low effort. Moreover, subjects with low Mg⁺⁺ basal levels seemed to have higher chances of disproportionately high lactate increases, typical for low scorers.
