Four athletes developed water intoxication (hyponatremia) during endurance events lasting more than 7 h. The etiology of the condition appears to be voluntary hyperhydration with hypotonic solutions combined with moderate sweat sodium chloride losses. The reason why the fluid excess in these runners was not corrected by increased urinary losses is unknown. When advised to drink less during prolonged exercise, three of the athletes have subsequently completed prolonged endurance events uneventfully.
四名运动员在持续时间超过7小时的耐力项目中出现了水中毒（低钠血症）。这种情况的病因似乎是自愿过度饮用低渗溶液并伴有中等程度的汗液氯化钠流失。这些跑步者体内液体过量却未通过增加尿液排出得以纠正的原因尚不清楚。当建议他们在长时间运动期间少喝水后，其中三名运动员随后顺利完成了长时间的耐力项目。
