Default Loop jump again, with short video :)

After my Flutz thread proved to be so helpful, I've uploaded a short (3 seconds!) clip of my Loop Jump. In this clip, I am not rolling, but trying to focus on getting my free leg into a better wrap position.

https://www.youtube.com/watch?v=3VPPDbUVP6E

It has highlighted a few errors to me, which I will list here:
  • Leaning forward and looking down half way though the rotation.
  • My free leg is a bit 'swingy' towards the back.
  • Free leg knee not coming up much.
  • Not much knee bend on landing.
Any advice to help me solve these would be gratefully received!
Do you guys see any other problems in addition to the above?

Thank you!

Hey. Looks good.

Yes, you need more down in order to go up.

Yes, it is a bit swingy.

Yes you are looking down.

I would get the right hand a little higher on the setup

Also, I would lift up more with the left knee.

All in all it is a decent jump. I would focus on the left leg and the head mostly.

This is my single loop from a couple of years ago. This is before I had my knee fixed. I had a lot of pain on the take-off and landing....well, I still have pain but it is a different pain now. :-(

Thank you Inverse!

11 in a row! Impressive

I think that, apart from looking down and and the free knee being low (as you said), both our loops look sort of similar. Not including the fact that I'm not moving of course.

I also think that because I am trying to get a low wrap, I am subconsciously looking down to check my position. I could be wrong though!

Aren't videos such a useful tool hey?

not bad, hard to do standing still, just get the free leg tighter and it will be better, oh keep your back straight and bend with the knee.

Not bad at all. The other comments are spot on and I have only one to add and one to note upon.

Note about standing still... Do it moving now. you can do it without a doubt. you will progress much faster if you practice moving and doing the loop or any jump and you will enforce leaning.

One addition: Get the left knee up higher. Forget the wrap, it will happen or not, it doesn't matter, but what does matter is to get that knee up. It will help you with lift and stability and landing. The more mass you have outside your center while rotating will cause an action like a gyroscope. It will be more difficult to wobble, but a slow rotation and slow movement and that same gyro will wobble a lot. For a great example, look at the vid from Inverse and see how high his knee gets on his free leg. you want it to look like that.

Another note on the loop combo's that Inverse did was that he started his rotation with 3 turns at a rate at which he would rotate on his jump and then did a fluid transition from 3 turn to jump, jump, jump... and he maintained that same rotational speed.

You are making great progress. You have a lot of us cheering for you. Have fun.

I want to add something that most skaters don't think about when using their arms and legs. A skater just does it and it works, but why does it work? It has a lot to do with physics and properties of centrifugal force.

I know this is dry, but if you can just bare with me for a few...

Have you ever looked at an old time generator with this funny contraption on top with 2 balls and arms that will extend and contract. Well that is called a centrifugal governor. It is used to keep the speed of a generator as constant as possible by moving mass in and out. Freestyle skaters do the same with their arms and legs. Here is a bit of info on the centrifugal governor: https://en.wikipedia.org/wiki/Centrifugal_governor

Just an extra note on the centrifugal governor. That article talks about 2 types, one uses gravity and goes up and down and the other uses springs that allow the weight balls to go out horizontally. Your arms using muscles work more like springs and your legs use gravity, so in effect you are using both types of governors to control your rotation.

As a skater you want to have your rotation match your jump height so that you can land at the proper time. Your arms AND your free leg are your centrifugal governor. Look at Inverness closely at how he keeps his rotation constant. Only minor adjustments in his arms and his free leg. Using physic and rotational properties will make jumps much easier.

Best of luck

Thanks Jim

Very interesting to read about centrifugal governors. I would imagine it is pretty hard to consciously adjust during a jump due to the speed which they occur, but would become almost instinctive as more and more experience is gained with the jump.

I have done quite a few loops rolling, and while I can usually get the rotation, I wasn't too happy with my position in the air. That is why I did a few stationary ones. It worked too, because you guys instantly picked up on my errors.

Next session, tomorrow, I'll work on fixing the low knee and doing it all rolling.

Thanks again!
