原文及翻译

1985, 16-year-old Douglas Casa ran the championship 10,000 meter track race at the Empire State Games. Suddenly, with just 200 meters to go, he collapsed, got back up, and then collapsed again on the final straightaway. With his body temperature at dangerous levels, he had suffered an exertional heat stroke. 

1985 年，16 岁的道格拉斯·卡萨 (Douglas Casa) 在帝国州运动会 (Empire State Games) 上参加了 10,000 米田径冠军赛。突然，在距离终点仅剩 200 米时，他倒下了，爬了起来，然后在最后的直道上再次倒下。由于体温处于危险水平，他患上了劳力性中暑。

Fortunately, with immediate and proper treatment, he survived the potentially fatal episode and has since helped save 167 people in similar circumstances. From ancient soldiers on the battlefield to modern-day warriors on the gridiron, exertional heatstroke or sunstroke has long been a serious concern. 

幸运的是，通过及时和适当的治疗，他从可能致命的事件中幸存下来，并帮助挽救了 167 名处于类似情况的人。从战场上的古代士兵到球场上的现代战士，劳力性中暑或日射一直是一个严重的问题。

And unlike classical heatstroke, which affects vulnerable people such as infants and the elderly during heatwaves, exertional heatstroke is caused by intense exercise in the heat and is one of the top three killers of athletes and soldiers in training.

与在热浪期间影响婴儿和老人等脆弱人群的典型中暑不同，劳力性中暑是由高温下的剧烈运动引起的，是训练中的运动员和士兵的三大杀手之一。
