Visualizations under hypnosis enabled nationally ranked Stanford male gymnasts to execute for the first time several complex tricks that they had been working on for over a year. The gymnasts were able to eliminate timing errors in the tricks, to increase flexibility, and, possibly, to concentrate strength. The rationale for the effectiveness of trance visualizations, the induction and deepening strategies used, and the effects are described. Also included is an example of the use of a translator for the induction of a subject with a minimal fluency in English. Implications for further use of hypnosis with athletes are suggested.
