Stomach secretory function under muscle load in the conditions of pharmacological blocade of M-cholinoreceptors and -adrenoceptors

Aim. The article deals with establishing the effect of muscle load on the stomach secretory function in the conditions of partial pharmacological blockade of M-cholinoreceptors and β-adrenoceptors in patients with duodenal acidification. Materials and methods. 22 males aged 18-23 years participated in the study. The stomach secretory function at rest under a 30-minute cycle ergometer load of 36 900 kgm combined with a partial pharmacological blockade of M-cholinoreceptors (1.5 mg per kg of body mass) and β-adrenoceptors (0.6 mg obsidan per kg of body mass) was studied using gastric and gastroduodenal intubation. Results. The blockade of M-cholinoreceptors at muscle rest provoked a noticeable decrease in the total content of electrolytes (p
