Athletes Should Just Chill--August 9, 2007

Some isolated studies have hinted that athletes might be better off if they can better dump off some of the heat their muscles generate. Now comes new research that adds credence to the idea that athletes indeed should just chill.

Other studies have tested the idea of cooling down athletes after their workouts to improve recovery, but this study looked at the effect of chilling them before their workouts to improve performance.

Scientists from a couple of German universities put more than 50 athletes into a cooling chamber, where the temperate was a frosty minus 120 degrees.  The athletes stayed in the deep freeze for two and a half minutes.  They then did an endurance run at 90 percent of their maximum capacity.  After six months, the cooled athletes showed much better results and a increased oxygen carrying capacity.

The scientists think that chilling slows the inevitable rise in body temperate that impedes performance.  Chilling also conserves body fluids, because the competitor doesn’t have to sweat as much to cool down.  Look for icy athletes at the summer Olympics next year in Beijing. 

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
