LEISEL JONES AT 30 m OF HER GOLD MEDAL 200 M BREASTSTROKE RACE AT THE 2007 WORLD CHAMPIONSHIPS IN MELBOURNE
Each frame of this analysis is .1 seconds apart. Leisel Jones' time for the 200 m breaststroke race was 2:21.84. This sequence is at 30 m and illustrates how quickly Leisel Jones settles into her technique. When viewing from above the surface, Leisel Jones clearly continues to move forward fast all the time that she is underwater. This series demonstrates why that occurs.
This stroke analysis includes a moving sequence in real time, a moving sequence where each frame is displayed for .5 of a second, and still frames.

At the end of the following narrative, each frame is illustrated in detail in a sequential collage.
Leisel Jones uses a four-part stroke: 1) arm propulsion with body and legs streamlined, 2) head rise and breathing with the hips and legs remaining streamlined, 3) arm recovery forward with the head and shoulders returning to a flat position, and 4) propulsive kicking against minimal frontal resistance. These phases mark several innovations when compared to "common" breaststroke and are worthy of emulation.
