Fifteen years ago I wrote some sound routines on a NeXT computer to  
help world-class rowers visualize a race the day before it was  
supposed to happen, mostly by getting them used to the cadence that  
would be required over 2000m, which changes from the start, to the  
settle, strategically placed power tens and twenties, and a final  
sprint.  The racers said listening to the simulation caused them to  
break out in a cold sweat.
