Seven well-trained adolescent boys with juvenile diabetes mellitus were studied. They were non-ketotic and performed a 60 min exercise in the afternoon at an average intensity of 58% of maximal working capacity. Blood glucose, blood lactate, plasma levels of insulin, C-peptide and 3-hydroxybutyrate, oxygen uptake and respiratory quotient were determined. The perception of exertion was scored as rate of perceived exertion. Healthy athletes of the same age were controls. Blood glucose, monitored continuously, decreased successively after 10-15 min of exercise with a significant correlation to the pre-exercise glucose value. Blood glucose decreased during exercise to the same level or below that of controls. Despite hypoglycemia with values of 2-3 mmol/l, the exercise continued. Plasma insulin was unchanged. The 3-hydroxybutyrate level was significantly higher in the diabetics, increased somewhat during exercise and still more during the recovery period. The diabetic subjects had significantly higher systolic blood pressure and heart rate during exercise despite a relatively equal work intensity and lower absolute workload. The rate of perceived exertion increased normally during exercise without interference of decreasing blood glucose.
对7名训练有素的青少年糖尿病男孩进行了研究。他们无酮血症，于下午进行了60分钟的运动，平均强度为最大工作能力的58%。测定了血糖、血乳酸、胰岛素、C肽和3-羟基丁酸的血浆水平、摄氧量和呼吸商。用力感知以自觉用力率评分。同龄健康运动员作为对照。持续监测的血糖在运动10 - 15分钟后连续下降，与运动前血糖值显著相关。运动期间血糖降至与对照组相同或更低水平。尽管血糖值低至2 - 3 mmol/l仍继续运动。血浆胰岛素未发生变化。糖尿病患者的3-羟基丁酸水平显著更高，运动期间略有升高，恢复期升高更多。尽管工作强度相对相同且绝对工作量较低，但糖尿病受试者在运动期间收缩压和心率显著更高。自觉用力率在运动期间正常增加，未受血糖降低的干扰。
