There's an interesting article over at Stanford Magazine about a new technique for reducing muscle fatigue in athletes. Apparently by rapidly cooling an athlete's hand, the athlete can train much harder as the muscles don't get as tired during repetitive exercise.

This technique of cooling the hand to reduce core body temperature works because mammals have specialised blood vessels in their palms that are designed to dissipate heat. By applying temperature changes to the palms, the core body temperature is more efficiently altered.

It's going to be interesting to apply this and see how much of a difference it makes to my own work-outs.
