ВЛИЯНИЕ МЫШЕЧНОГО И ЭМОЦИОНАЛЬНОГО НАПРЯЖЕНИЯ НА ОБЪЕМ СЛЮНЫ, ЖЕЛУДОЧНОГО И ПОДЖЕЛУДОЧНОГО СОКОВ И МОЧИ У ЛИЦ С РАЗЛИЧНЫМ УРОВНЕМ ПОВСЕДНЕВНОЙ ДВИГАТЕЛЬНОЙ АКТИВНОСТИ

Abstract

Aim. To study correlations of volumes of saliva, gastric and pancreatic juices, urine, and sweat in people with different levels of daily physical activity (track and field athletes, skiers, and martial arts practitioners) and people not engaged in sports – at rest, during exercise, and under emotional tension. Materials and Methods. Gastroduodenal probing was used to assess volumes of saliva, gastric and pancreatic juices, and urine in 117 men aged 18–23 at rest and under muscle and emotional tension. Results. It was established that at muscle rest there was an inverse correlation between levels of gastric and pancreatic juices. Under muscle and emotional tension this correlation became stronger (r = –0.74; P = 0.001). Along with that, the preserved high functional activity of the secretory apparatus of the stomach and pancreas after exercise and emotional tension was accompanied by the decreased tension of salivation and urination, especially after combined muscle and emotional tension. Conclusion. There are compensatory relationships between levels of secretion of gastric and pancreatic juices: the pronounced reduction of gastric juice volume is associated with a maintenance or growth of the pancreatic secretion level; and, vice versa, the decrease of pancreatic secretion is accompanied by the increased secretion of gastric juice.
