Researchers at Stanford have developed a thermal exchange glove that is able to cool a person’s core temperature very quickly — in a matter of minutes. 

The glove’s effects on athletic performance didn’t become apparent until the researchers began using the glove to cool a member of the lab – the confessed “gym rat” and frequent coauthor Vinh Cao – between sets of pull-ups. The glove seemed to nearly erase his muscle fatigue; after multiple rounds, cooling allowed him to do just as many pull-ups as he did the first time around. So the researchers started cooling him after every other set of pull-ups.

“Then in the next six weeks he went from doing 180 pull-ups total to over 620,” said Heller. “That was a rate of physical performance improvement that was just unprecedented.”

Kottke concludes:

I expect this will be either everywhere in pro sports in a couple of years or banned.
