Abstract
A percutaneous electrogastrogram (EGG) is a simple and low-restraint way to measure the electrical activity of the gastrointestinal tract. An electrogastrogram examination is a noninvasive method of evaluating gastrointestinal motility and autonomic nervous system activity. However, EGGs are not as widely used in clinical settings as electrocardiograms (ECGs) or electroencephalographs (EEGs) because an EGG can be impacted by electrical activity from the myocardium and the diaphragm (due to respiration), and there is no method to relate the functions of the stomach to the data obtained. This paper examines the effect of exercise on gastric electrical activity using two exercise intensities to confirm the basic biological response of an EGG. It was found that, after high-intensity exercising, the spectrum density at the normal frequency band of the stomach (2.4-3.7 cpm) decreased, which may indicate a decline in gastric activity taking place during exercise. Moreover, after high-intensity exercise, translation error increased significantly. Exercise intensity is thought to affect the electrical activity of not only the gastrointestinal tract, but also of other organs.
Highlights
The intestines, which are referred to as “the second brain,” are part of the digestive tract, and are linked to the brain through the autonomous nervous system and intercellular messages, such as hormones and cytokine [1]
This study examines the impact of exercise intensity on gastric electrical activity by a participant undergoing an EGG during exercising
The results showed that for high intensity exercise, power spectral density (PSD) in the gastric normal frequency band tends to decrease, presumably indicating a temporary decline of gastric activity caused by the exercise
Summary
The intestines, which are referred to as “the second brain,” are part of the digestive tract, and are linked to the brain through the autonomous nervous system and intercellular messages, such as hormones and cytokine [1]. A part of the intestines produces a precursor of serotonin, which maintains a person’s overall physical health, and helps stabilize the heart [3]. Maintaining healthy intestines contributes to mental and physical health. Intestinal floral boom has attracted interest in the fields of intestinal environment and health. To regulate the intestinal environment, people must eat carefully, exercise, and rest. Exercise promotes circulation and keeps the autonomous nervous system healthy, maintaining the autonomous nerves in this way can encouraging peristaltic movement of the intestines [4,5]. Results in sympathetic nerve dominance, which suppresses digestive tract functions.
