KIEREN PERKINS AT 570 m OF HIS SILVER MEDAL 1500 m RACE AT THE 2000 AUSTRALIAN OLYMPIC TRIALS IN SYDNEY
Each frame is .1 seconds apart. Perkins' time in this event was 15:01.10 seconds. 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.
The purpose of this brief analysis is to demonstrate the decline in Keiren Perkin's stroke from that which he displayed at the 1992 Olympic Games.

At the end of the following narrative, each frame is illustrated in detail in a sequential collage.
The loss of propelling efficiency, when compared to Perkins' 1992 technique, means that he no longer is capable of achieving former performance levels. Forces he generates, to a larger degree, are now dissipated vertically rather than horizontally.
To match 1992 times, the swimmer would have to exert much more energy per stroke with today's form. Since growth has stopped, it is highly unlikely that Keiren Perkins has developed any more physiological capacity than that displayed in 1992. Thus, more resources will be squandered per stroke with the current technique. To avoid excessive fatigue in a race, the swimmer will have to go slower.
