Ten hyperplastic obese women were trained physically on an ad-libitum diet preventing them from losing weight. Plasma-insulin concentrations decreased during oral glucose-tolerance test (OGTT), an effect which was more clearly seen after atropine administration. After intravenous-glucose administration (IVGTT) these effects were absent or much smaller. Insulin secretion stimulated by the sight and smell of food (CIS) was more pronounced after training, this increase being abolished by atropine. Physical training produces vagotony with well-known effects on circulatory variables such as a slower resting heart rate. Both the results after OGTT and CIS show the effects of increased vagotony also on insulin secretion. This effect tends to hide the insulin-concentration-lowering effect of physical training. This consequence of training is possibly dependent on enteric factors associated with insulin secretion since it was not found after IVGTT.

过度肥胖的体育锻炼。V.阿托品对血浆胰岛素的作用。

十名肥胖的增生肥胖妇女接受了随意饮食的身体训练，以防止她们减肥。口服葡萄糖耐量试验（OGTT）期间血浆胰岛素浓度降低，这种作用在阿托品给药后更为明显。静脉内葡萄糖给药（IVGTT）后，这些作用消失了或很小。训练后，视觉和嗅觉刺激的胰岛素分泌更加明显，阿托品消除了这种增加。体育锻炼会产生迷走神经，对循环变量（如静息心律变慢）产生众所周知的影响。OGTT和CIS后的结果均显示，迷走神经增多对胰岛素分泌也有影响。这种作用倾向于掩盖体育锻炼降低胰岛素浓度的作用。
