研究表明:经过耐力训练的运动员其肾上腺素分泌水平在低血糖时和经过相同的有关工作负荷后要比没经过训练的个体高。我们假设运动训练能增加肾上腺髓质的分泌能力,为证明这一假设对胰高血糖素(每70公斤体重1毫克,静脉注射)、急性血碳酸过高(吸入的氧只有7%)和急性低气压缺氧(吸入的氧分压只有87毫米汞柱)的作用进行了研究。研究对象是8个经过耐力训练的运动员和7个从事办公室工作的成年男性。前者为检测组(氧摄入量=66毫升/分/公
Studies have shown that endurance-trained athletes have significantly higher levels of adrenaline secretion at hypoglycemia and after the same relevant workload than those who are untrained. We hypothesized that exercise training would increase the secretion capacity of the adrenal medulla. In support of this hypothesis, glucagon (1 mg per 70 kg body weight intravenously), acute hypercapnia (only 7% of inhaled oxygen) and acute The effects of hypobaric hypoxia (inhaled oxygen partial pressure of only 87 mm Hg) were studied. The subjects were eight endurance-trained athletes and seven adult males working in the office. The former for the detection group (oxygen intake = 66 ml / min / male
