Study on Human Intragastric Pressure During Exercise

Abstract

Intragastric pressure at gastric empty state was measured by radio capsule method during various exercises in three human subjects. The E. I. L. Type. 70. pressure sensitive radio capsule of England make was used in this experiment. 1) The empty intragastric pressure at rest was 30.0-33.0 cmH2O and the gastric peristalsis was 2-3 sec. in frequency and less than 3 cmH2O in amplitude. 2) The resting gastric peristalsis was disappeared immediately after the onset of deep respiration or exercise. The pressure raised to maximum 76.0 cmH2O at the end of deep abdominal inspiration. 3) The intragastric temperature raised during various exercises and increasing grade was showed in Table of the text. © 1978, The Japanese Society of Physical Fitness and Sports Medicine.
