New testing reveals using a cooling glove greatly increases physical performance.
"But 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.'"
