Definitely not a new idea and definitely not my original idea. I first saw this type of experiment with collegiate athletes for some University I don't recall around five or six years ago. It works, I've used it, and even Bas Rutten has mentioned in interviews before, I believe, that cornerman should be putting ice on the head to reduce swelling. The issue is the bag of ice isn't cold enough to really do anything in 60 seconds and doesn't make contact with a large enough surface area of skin. Which is why submerging the feet and hands in ice water, with salt, is absolutely necessary. This is combining another principle from Chemistry that I don't see many trainers/fighters/cornerman use or understand. There are similar ideas for breathing, but this isn't the thread for that topic. The original idea is getting two buckets of ice water, with salt, and bringing that into the corner for fighters to submerge their feet in, and if I ever get my way and gloves are no longer needed in MMA, the hands will go in as well.
