Notable Features

Because of the unusual angle of this film series, a complete frame by frame analysis is not provided.

Although Andrei Serdinov is one of the best butterfly swimmers in the world there is still room for improvement. If he altered his stroke to remove the repositioning of the arms outward (Frames #2-5), an inertial lag would be eliminated. The resulting greater proportion of productive propulsion, which is a feature that appears to be entering into butterfly techniques at this time, should result in an improved time.
