Abstract
The blood glucose response of a male ultramarathon runner was monitored throughout a 1005-km race. Before the race the runner had a fasting blood glucose concentration of 5.1 mM. At no stage during the race were his mean blood glucose levels less than 5.8 mM. This was partially attributed to the eating patterns of the athlete, the times at which blood samples were taken, the glycaemic index of food ingested and hyperglycaemia. While there was no evidence of glucosuria, ketones were present in the urine on one day of the event. There were other signs suggesting that at various stages of the event the runner had a metabolic acidosis. Possible reasons for this are discussed.
摘要
在一场1005公里的比赛中，对一名男性超级马拉松运动员的血糖反应进行了全程监测。比赛前，该运动员的空腹血糖浓度为5.1毫摩尔/升。在比赛的任何阶段，他的平均血糖水平都没有低于5.8毫摩尔/升。这部分归因于运动员的饮食模式、采血时间、摄入食物的血糖指数以及高血糖症。虽然没有糖尿的证据，但在比赛的某一天尿液中出现了酮体。还有其他迹象表明，在比赛的各个阶段，该运动员存在代谢性酸中毒。文中讨论了可能的原因。
