rapidly cools body temperature, greatly improves exercise recovery, and could help explain why muscles get tired.
Why a glove? There you have a special network of veins.
These networks of veins, known as AVAs (arteriovenous anastomoses) seem exclusively devoted to rapid temperature management. They don’t supply nutrition to the skin, and they have highly variable blood flow, ranging from negligible in cold weather to as much as 60 percent of total cardiac output during hot weather or exercise.
Why is it better than Ice baths?
The method is more convenient than, say, full-body submersion in ice water, and avoids the pitfalls of other rapid palm-cooling strategies. Because blood flow to the AVAs can be nearly shut off in cold weather, making the hand too cold will have almost no effect on core temperature.
I think their title is pretty exaggerated. ‘Better than steroids’ I doubt that. But hey, that’s how you get in the news.
Palm cooling allowed to get more volume (in an already volume-oriented workout), so the gain is an endurance gain. No data on strength or mass gains…
