Brief content of the article:
The researchers studied the response in the plasma of total, intracellular and ionized Magnesium and total and ionized Calcium. Further parathyroid hormone serum concentrations and 1,25 –dihydroxyvitamin D concentrations were measured. The response was studied in eleven clinically healthy stallions under standardized conditions on a treadmill. The researchers concluded that additional Magnesium and Calcium supply is superfluous in the case of a single prolonged exercise. Body stores are sufficient to replace Mg and Ca losses in Sweat. However, these bodystores have to be replenished during recovery. The researchers suggest that a higher dietary supply in hard working and heavily sweating sports horses may be benificial the prevent low ionized calcium and magnesium values.
