2018 TYR PRO SWIM SERIES – INDIANAPOLIS
It’s always very easy and at the same time really amazing to analyze the terrific performance of Katie Ledecky.
With the collaboration of Stefano Nurra, a video analyst and coach for the Turkish Swimming Federation, the Energy Standard Swim Club, and the Austrian Swimming Federation, we present an analysis of Ledecky’s race.
Even if the data table shows an almost perfect management of the race, I am not willing to give up the idea that perfection does not exist.
First of all, the management of the speed is very interesting. The time recorded at the end of the first 300m is the fastest and very close to the time recorded for the last 300m.
For the second 300m we recorded the slowest time. After that there is a great progression: 3:02.50 – 3:05.79 – 3:04.91–3:04.74 – 3:02.54. The race respects the scheme 1/5/4/3/2.
Ledecky Race Strategy
The race strategy is an important debating point for a lot physiologists and sport scientists.
According to the latest theories the biomechanical point of view plays an important role for the short race but for the middle distances the metabolic point of view clearly gains in importance.
The dynamic of lactate production and accumulation and the dynamic of activation of Max Vo2 is one of the main topics of discussion.
The “metabolic way” explains that Katie’s strategy (in order of speed 1st part, 5th part, 4th part, 3rd part and 2nd part) is the best solution to avoid accumulating too much lactate too quickly. At the same time it’s the best way to allow the right activation of MaxVo2.
Another interesting topic is the management of the balance between stroke rate- stroke length. In the first 100m the SR is higher and the SL a little bit shorter. After this point the balance is almost consistent until the 14th 100. There it looks like she was preparing the last one.
In the 14th 100 she increased the SR reducing the SL. In the last one she increased the SL keeping the same SR in order to close the race in the best way.
Last but not least we have to consider the efficiency of the turns:
- The speed shows us the correct difference between turns and swimming, from the beginning to the end
- She is able to keep almost the same time at every turn from the beginning to the end. That’s incredible!
All the parameters we spoke about and the final result are certainly indicative of a very precise and accurate training.
Nothing was left to chance.
