[The behaviour of basal gastric secretion during exercise and restitution in chronic gastric and duodenal ulcer patients (author's transl)].
The behaviour of basal gastric secretion was examined in 15 gastric ulcer patients, 54 chronic duodenal ulcer patients, and 25 normal subjects. The investigation was conducted with the subjects remaining seated in three 1-hour phases at rest, during exercise, and in the course of restitution. The 60-minute exercise was performed on Monark's bicycle ergometer with loads producing constant heart rate acceleration ca 50% of the maximum for the subjects' age. The determination made included gastric juice volume, hydrochloric acid concentration and basal acid output (BAO) as well as sodium, potassium, chloride, calcium and magnesium levels in gastric juice. It was found that in healthy subjects a 1-hour exercise of constant 50% load significantly decreased the volume of gastric juice, concentration of hydrochloride acid and BAO as well as electrolyte content (rho less than 0.05): these changes were especially distinct during the restitution period. In the patients with gastric ulcer the basal gastric secretion presented a similar picture. By contrast, in the duodenal ulcer patients exercise produced increased volume of gastric juice and increased BAO values as well as higher electrolyte contents (rho less than 0.05). During the restitution period none of these values decreased below those determined at rest.
