Olympic swimmer and University of Georgia alumna Kara Lynn Joyce agreed to wear sensors on her body while she performed the kick, giving engineers a chance to record her movements and determine the kick's effectiveness.
The engineers concluded that perfecting the dolphin kick could help a swimmer shave whole seconds off his or her time. In fact, the move is so effective that Olympic swimmers are only allowed to use it for the first 15 meters off the pool wall.
