I'm just throwing stuff out at random:
The closest comparison I make between dancing and another "sport" is between ballroom dancing and dressage (equestrian), with the exception that Dressage is typically (unless it's a free-style) a pre-established pattern of movements and transitions, and it's performed one horse/rider team at a time. The precision, technique, and training are very similar.
I have no idea where you're going with your paper, other than "Dancing ROXORZ", but stick with the basics- dancing's fun, it's a great communication tool, it's beneficial to mind/body, etc.
