Fresh off her record-setting performance in London, Rebecca Soni is arguably the top female breaststroker in the world. The technique she uses has some noteworthy aspects: a high turnover coupled with short arm stroke, wide elbow recovery, and quick kick.
Since breaststroke takes place entirely underwater, stroke efficiency is crucial. Dr. Brent S. Rushall has analyzed Soni’s breaststroke based on underwater video taken during her 200 breaststroke in the 2008 Beijing games. A post in the USMS Discussion Forums collects several commentaries on Soni’s breaststroke, including links to an entire thread devoted to discussing this highly technical stroke.
