Leveraging the high number of specialized heat-transfer veins in the palm of the human hand, researchers at Stanford have developed a thermal exchange glove that is able to cool a person's core temperature in a matter of minutes. Turns out this is helpful for athletes.
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 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."
The researchers applied the cooling method to other types of exercise - bench press, running, cycling. In every case, rates of gain in recovery were dramatic, without any evidence of the body being damaged by overwork.
