There have been ongoing efforts to include DanceSport in the Olympic Games, with advocates highlighting its athletic and artistic qualities.
Hip action - Latin technique is required; and athletic and balletic maneuvers are incorporated which makes it into a DanceSport.
Two Latin dances are progressive going counter clockwise (samba and paso doble), but there is no obligation to consistently move round the floor.
In Smooth, dancers wear costumes not greatly dissimilar to those worn by their counterparts in Standard---Standard dresses often have prominent floats embellishing the arms and fuller skirts which are typically absent in Smooth, due to the open movement and changing arm positions requiring less restriction on the body; however, the dances themselves are significantly different as a result of influence by dancers like Fred Astaire and Arthur Murray in the years following World War II.
The Rhythm dances were also influenced by American dancers of the post-World War II era, but the differences between it and International Latin are more subtle.
