Before-after: Figure skating technique
Wondering the real effect of video training? I mean how training with video support can help improve a skater's technique. Deliver a unique free skating instruction for your athlete.
While working as a coach and video analysis expert in Andorra for Iceplanet summer camp, a skater's parent asked me about the benefits of video analysis session for her daughter. Excellent inquiry I said! Since I've been working with this technology for 11 years, I'm totally convinced about its usefulness, especially when you take in consideration that 65% of the world's population are visual learners.
Using video for training like video session with instant visual feedback or, video analysis, is a real asset because skaters and coaches can see all the movements details. That's the moto of Perform'Live.
Now, on to before and after video training/analysis. Let's take as an example Leonid Sviridenko. He is a young russian skater who before getting a recent injury started performing quad salchow and quad flip on a regular basis.
The first time we worked together, he could land triple jumps but I could tell that he had a clear problem with his body's axis in the air resulting in a low percentage success rate. He was really tilted in the air, Leonid had almost the same position than Yuzuru Hanyu, the japanese legend with back to back Olympic titles. For Yuzuru, that tilt in the air doesn't seem to be a problem but for Leonid it really is (Average body axis angle of Yuzuru Hanyu in a quad toe-loop around17° / average observed body axis angle for a quad toe-loop around 13°).
Picture below, an advanced video analysis of a triple lutz with a stromotion effect. I added the body axis angle of Leonid and the average data of his technique to get a gobal view of the problem.

After doing an advanced video analysis, I noticed that his arms movement amplitude was too big. During the take-off, his arms were going too high, creating an interference or conflicting movement which in the end slowed down the rotation time and created body axis issues.
On his triple salchow, we can see clearly on the pic below that before his elbows were over his shoulders line and how its impacted his body axis angle in the air.
