Abstract

The effect of intermittent moderate exercise on the passage of a solid meal, labelled with radioactive Technetium sulphur colloid, through the stomach and small intestine was investigated by paired studies on seven healthy volunteers. Measurements of gastric radioactivity and breath hydrogen exertion were recorded every 10 minutes while subjects exercised in a controlled manner while seated on a bicycle ergometer. These were compared with values obtained during a separate experiment while the same subjects sat upright in a chair. Exercise significantly accelerated gastric emptying (control t 1/2 = 1.5 +/- 0.1 h; exercise t 1/2 = 1.2 +/- 0.1 h; p less than 0.02) but had no significant effect on small bowel transit time.

摘要

通过对7名健康志愿者进行配对研究,调查了间歇性适度运动对一顿标记有放射性锝硫胶体的固体餐食通过胃和小肠的影响。在受试者坐在自行车测力计上以受控方式运动时,每10分钟记录一次胃放射性和呼出氢气量的测量值。将这些值与在另一个实验中同一受试者直坐在椅子上时获得的值进行比较。运动显著加速了胃排空(对照组t1/2 = 1.5 +/- 0.1小时;运动组t1/2 = 1.2 +/- 0.1小时;p < 0.02),但对小肠转运时间没有显著影响。
