Abstract
Behavior of the basal gastric secretion of electrolytes, lactic acid and pyruvic acid was studied in 20 min portions in 14 healthy men during rest, exercise and restitution. On the bicycle ergometer in a sitting position all of the men performed the average work 15, 120 .+-. 1800 kpm [kilopound meter] during 20 min. Basic gastric secretion didn''t change significantly during exercise, but its significant decrease occurred during 20 min restitution after exercise. During restitution secretion of Cl, Mg and Ca decreased, while their concentrations didn''t change in gastric juice. During physical exercise the lactic acid secretion in gastric juice increased. It was higher during restitution than in the rest period (P < 0.001) and during exercise (P < 0.02).
