The effect of strenuous physical exercise on postprandial gastric acid secretion and gastric emptying was evaluated in untrained healthy volunteers. Subjects exercised for 45 min on a stationary bicycle at 50 or 70% of their maximal work load, beginning 45 min after a steak meal. Compared with a control study during which subjects sat on the bicycle without exercising, exercise had no significant effect on the gastric acid secretory response to the meal (control, 31.9 +/- 8.3 mmol/120 min; exercise, 32.2 +/- 7.8 mmol/120 min) or on the amount of nonabsorbable meal marker that emptied from the stomach in 120 min (control, 88 +/- 3%; exercise, 87 +/- 4%). Increases in serum triglyceride levels after the meal were also unaffected by exercise, suggesting that absorption of dietary lipid was unimpaired by exercise. These studies indicate that strenuous exercise shortly after a meal has little effect on postprandial gastric secretory or motor function in humans.
在未经训练的健康志愿者中评估了剧烈体育锻炼对餐后胃酸分泌和胃排空的影响。受试者在进食牛排餐后45分钟开始，以其最大工作量的50%或70%在固定自行车上锻炼45分钟。与受试者坐在自行车上不锻炼的对照研究相比，锻炼对餐食的胃酸分泌反应（对照：31.9±8.3 mmol/120分钟；锻炼：32.2±7.8 mmol/120分钟）或120分钟内从胃中排空的不可吸收餐食标记物的量（对照：88±3%；锻炼：87±4%）均无显著影响。餐后血清甘油三酯水平的升高也不受锻炼的影响，这表明运动不会损害膳食脂质的吸收。这些研究表明，餐后不久进行剧烈运动对人类餐后胃分泌或运动功能影响很小。
