Flow visualization of competitive swimming techniques: the tufts method.
The purpose of this study was to evaluate the use of tufts to visualize the flow of water around the trunk and limbs of a swimmer. Numerous pilot studies were conducted to evaluate the effectiveness of different tuft materials, dimensions and methods of attachment for recording the characteristics of the flow around a swimmer performing various strokes and drills. Differences in the patterns of flow made visible by the tufts suggested that this method of flow visualization may well be useful in resolving both basic and applied questions concerning swimming techniques.
