This is the next instalment in a series that looks at how the elite swim the 200 by looking at their race splits. This time we’re analyzing the 200 butterfly for women.
In the 200 freestyle and backstroke analyses (here, here and here) we found a number of surprises, or at least things that surprised me. While the top 24 swimmers generally displayed all three race profiles (Sprinter, Distance and Hybrid – see below), the individual races were won by either fast sprinters who got out ahead and couldn’t be caught (women’s freestyle and backstroke), or by more distance-oriented swimmers who ground out an incredible last 100 (men’s freestyle and backstroke).
Now that we’re starting to analyze the short axes strokes, it will be interesting to see if this pattern changes.
The data set consists of 24 elite swimmers at the time of the 2012 Olympics. I used the fastest 24 times from the Olympics and the US Olympic Trials. For each swimmer, I used the fastest time they swam during the competition, and not just their last swim. I also knew that I would have to look at more than just raw splits, in order to compare sprinters to more distance-oriented swimmers, and to provide value to non-elite swimmers. As a result, I used their 50 m Personal Bests [PBs] as well. For a few swimmers for which the 50 PB was unavailable or absurdly old, I either had to infer their 50 PB from their split on a 100, or else exclude them from the analysis.
I introduce the term “offset” to mean a split minus that swimmer’s PB.
Offset 50 = 50 Split minus 50 PB
The analysis is divided into 3 sections.
