Petra Vlhova

With the Mens’ and Ladies’ GS and SL World Championship events starting tomorrow I am republishing my March 28, 2017 post on Petra’s performance in the Aspen Slalom where I said,

This was not the same Vlhova I had analyzed earlier in the season. Vlhova has definitely changed and it is for the better.

The degree of neurobiomechanical function permitted within the structures of a ski boot, more than any other factor, can literally determine who stands on the podium. The GS and SL World Championship events will show which racer has the functional edge.

As time permits, I analyze the movement and loading patterns of elite skiers such as Mikaela Shiffrin, Lindsey Vonn, Ted Ligety, Tessa Worley and others. Occasionally, a source sends me video of these racers training.

I have identified a specific movement and loading sequence pattern that I use to analyze technique. This requires decent quality video and specific camera angles. In a future post, I will describe the process, the key metrics I look for and what they indicate.

Up until I saw the video of Vlhova, that is the subject of my post, SUPER PETRA VLHOVA’S EXPLOSIVE IMPULSE LOADING IN ASPEN SLALOM, I rated her as one of the better technical racers on the World Cup circuit. But I did not consider Vlhova to be in the same class as a Shiffrin or a Worley.

When someone posted a link on FaceBook to Vlhova’s winning run in the Aspen slalom, I was stunned by what I saw in the first few gates. This was not the same Vlhova I had analyzed earlier in the season. Vlhova has definitely changed and it is for the better.

SUPER PETRA VLHOVA’S EXPLOSIVE IMPULSE LOADING IN ASPEN SLALOM

I am blown away by the explosive impulse loading of her outside ski that Petra Vlhova displayed in winning today’s World Cup Slalom in Aspen, Colorado. Vlhova’s powerful impulse loading made other racers, including Shiffrin, look like they were in slow motion in comparison. There are several videos of Vlhova in action on YouTube already.

For those who don’t know how to change video speed and definition in YouTube, the screen shot below shows the range of speed options available from 0.25 to 1.5 times Normal. To select the speed option, click on the gear that says HD then select Speed. I usually watch race videos in several speeds, including pulse frame stepping using the space bar on my keyboard.

Vlhova’s rapid and explosive loading of her outside forefoot at edge change literally supercharges the small nerves in her feet and the muscles in her foot to pelvic core in a way that transforms her into a literal super racer.

Petra; on it – all over it.

Here’s a short video clip in reduced speed of Super Petra in action. In one word; WOW!

Bravo Petra Vlhova! You made my day.
