60秒科学:Heat Fells More Distance Runners Than Do Hearts

听力内容:

60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

Long-distance runners may at times worry about their heart health while pounding out the miles. But a study finds that heat stroke fells many more runners than does a bum ticker.

Heat stroke can damage a person’s brain, heart, kidneys and muscles. And new data underscores the toll it takes.

Researchers examined health records from more than 130,000 runners who competed in events in Tel Aviv during a seven-year span. The analysis revealed that distance runners were 10 times more likely to experience heat stroke than serious cardiac problems. All the fatal or life-threatening events were from heat stroke. The study is in the Journal of the American College of Cardiology. [Lior Yankelson et al, Life-Threatening Events During Endurance Sports: Is Heat Stroke More Prevalent Than Arrhythmic Death?]

The researchers advise runners to take 10 to 14 days to adjust to the climate before tackling a serious run in a hot region. And they say to sit out the run if you’ve been sick recently.

Perhaps one day runners will swallow internal temperature sensors that reliably record core body temperature. But for now runners should simply do their best to keep cool.
