For those who do ultra running you might find this article in the NY Times interesting it discusses the use of dissociation and how it clearly works:
Dr. Morgan, who tested the method in research studies, said he was inspired by a story, reported by an anthropologist that, he suspects, is apocryphal. It involves Tibetan monks who reportedly ran 300 miles in 30 hours, an average pace of six minutes a mile. Their mental trick was to fixate on a distant object, like a mountain peak, and put their breathing in synchrony with their locomotion. Every time a foot hit the ground they would also repeat a mantra.
So Dr. Morgan and his colleagues instructed runners to say “down” to themselves every time a foot went down. They were also to choose an object and stare at it while running on a treadmill and to breathe in sync with their steps. The result, Dr. Morgan said, was that the runners using the monks’ strategy had a statistically significant increase in endurance, doing much better than members of a control group who ran in their usual way.
