Performance video: Quad lutz with Vincent Zhou

“Excellence is in the details. Give attention to the details and excellence will come”. Perry Paxton.

I would say this quote is the motto for all elite athletes and coaches.

As a video analysis coach, I am impressed with skaters who can keep high performance through years. I did a performance comparison of Vincent Zhou, 2017 World Junior Champion. The technique of his quad lutz did not change so much. We can see this easily with the 2 advanced stromotion below.

A little disclaimer about 2019, the original video quality caused me few troubles during the editing.

The speed before the jump is one of the key points for a quad. Unfortunately, this feature is difficult to collect from this kind of video/camera angle. Anyway, it seems that Vincent got more speed. In 2019, his upper body angle is a little bit lower ( around 55°, in 2017, he was around 47°).  With the experience he gained, he became more confident with this quad jump.
