Yuzuru Hanyu: Quad lutz

Back to the Future

At the end of October 2017, I did an advanced analysis of the quad lutz performed by Yuzur Hanyu. It was a premiere for him. Since then, the Japanese champion won his second Olympic title.

The first part of the 2019-20 season ended with the grand Prix Final in Torino last week. A number of figure skating fans have asked to get a new analysis of his jump.

Sui Han throw jump with data Grand Prix Final Torino 2019

Since the last Figure Skating World Champhionships, the offical broadcast provides for only one jump (for this moment) to be analysed, with data such as length, distance and landing speed. This is done by using calibrated imaging. Fans are really interested by this kind of data which details a performance without human judgement. As I'm watching carefully to understand and analyze the jump mechanic, I notice that the trajectory drawn by the broadcast tv system is incorrect sometimes.

This is the 3 different kind of trajectories you can observe for figure skating jumps, the trajectory of a throw jump is clearly different. Maybe you recognize the trajectory done during a delayed jump ( 3. in the drawning below) .

Of course, the way I obtain data is not quite as accurate as the technology used by the broadcast tv. I would be curious to know the margin of error of this system. Anyway I have already noticed that the data i collected is a good approximation of the data from calibrated imaging. I know that some fans are also interested to know how I calculate and get my data.

figure skating fan comment

 

Today, on Instagram, Tapockar commented this. He is right with his formula. In the execution of any quad jump, we should take more in consideration the skating speed before the jump. The commom jump trajectory is the trajectory noted 2. (cf. drawning above).

 

  

That’s why using average and median data to work with the skaters is the best method, especially when you consider each skater as unique. This data can really help to develop their specific techniques.

I really think Yuzuru and his coaching team followed this quote.
