PSIA Ramp Clinic

post #1 of 8
Thread Starter 

Just returned from the PSIA-E ramp clinic.

 

This was a great event that combined learning with a ridiculous amount of fun.

 

Here is a video of how things went.

Looks like progress. You taking this to the snow?

That is indeed me. There were many more there with more talent and fun to watch but I would not presume to post someone else's video.

 

It was a great group that showed the strong cross section of the skiing population the PSIA has as members. There were enthusiastic level 1 members trying to jump for the first time, senior skiers doing full twisting layouts, to younger boarders throwing off axis doubles.

 

The weather was perfect, and it was so nice to spend time around a group of ski folks a few months prior to the snow flying.

Kneale,

 

I went to see if the body can still do some jumps after a 30 year absence. The results are in and there is a small glimmer of muscle memory.

 

Last year I decided to get back into the things in life that made me happy. I started skiing again after a 15 absence and attended many of the PSIA clinics to get back up to speed as fast as possible. The ramp clinic was one that held the promise of a fun outing.

 

Ramping has always been the best training for jumping on the snow. It allows you in a relatively painless way of judging your aptitude. The most important lesson to be learned on the ramp is what you are not ready to try on snow. That being said, there will be no inverterted jumps on snow for me. The 360's I feel I am close enough to to move to snow.

 

Most important thing that I took away was some basic progressions that I can teach to kids who want to play in the parks. This is an ever growing population on our mountains and we need instructors to have at minimum, basic understanding of jumps to guide the younger skiers if called upon to teach in the park.

Good on you Lokie!  That would make for a fun clinic.  It would be interesting to get back into the air again.

 

How much did the aerated water help (the bubbles)?  Saw the jumpers using them at the pool at the Park City Training Center and made me wonder.  Is it just for spotting the landing or does it help to soften the landing?

The bubbles are to soften the landing but I had longer stiff skis and coming in short on a back really put alot of stress on the calf muscles. Landing sideways in an upright jump did not hurt at all. When I go back next year I will defiantly find a pair of short soft straight skis. Because you do not want to be diving for the skis in 18' of water we set the bindings to maximum din so they do not release. This transfers a great deal of leverage to your leg muscles if you are flipping and come up short.

Years ago we did not have bubbles but I had super soft Olin ballet skis to jump. I never had sore legs after but weather it was the short skis or 18 year old legs is had to quantify.cool.gif

A very funny observation by one of the participants:

 

 

Chip’s Theory of Jumping Relativity was formulated in 2003 during the inaugural PSIA-E jumping event held at Lake Placid, New York. 

The theory is based on the following postulations:

  1. Jumping is good for the heart, soul, and spirits.
  2. Landing (correctly) is good for the body.
  3. Jumping is comprised of  (4) equally important components:
    1. The approach
    2. The takeoff.
    3. The stunt (now known as maneuver in the Park Safety Program).
    4. The landing.
  4. Time has an effect on jumping:

The wisdom of age has enlightened me to the ever-changing dynamic relationship between jumping and time.  This relationship is best represented by Chip’s Theory of Jumping Relativity, which states a good jump (GJ) is equal to the approach and takeoff (ANT) times your age, plus the stunt (S) times the reciprocal of your age times correction factor (CF - if you are less than 40 years of age this equals 1, if you are 40 or older this equals 1/2) divided by your intelligence (IQ), plus the landing (L) times your experience (EXP).  This relationship can be empirically represented as follows:

GJ = (ANT * AGE) + (S*(1/AGE)/IQ*CF) + (L*AGE*EXP)

Where:

            GJ =     Good Jump

            ANT =   Approach & Takeoff

            AGE = Age of the Jumper

            S =       the stunt

            IQ =      Intelligence of the jumper

            CF =     1 if age<40 or ½ if age>39

            L =       Landing

            EXP = Years of experience jumping

As you can see from this formula the approach, takeoff and landing have little value to younger jumpers, for young jumpers it’s all about the stunt.  As the age of a jumper increases the approach, takeoff and landing gain in value however the stunt remains very important.  At age 40 the value of the stunt deteriorates rapidly.  Also as the age of a jumper increases so will the value of the approach, takeoff and landing.  There will be a point in a jumper’s career (older and wiser) when the landing will become the single most important component to the jump. 

In 2005 further research in this area and some preliminary findings indicate there may exist an over 50-correction factor that needs to be applied to above formula. 

So the creator of Chip’s Theory of Jumping Relativity continued research again during summer of 2007 at Lake Placid and the finds were:

For jumpers over the age of 50, the correction factor (CF) continues to diminish in value at a rate that appears to be inversely proportional to age, however this was affected by other external factors including:

1.       Over the counter non-steroidal anti-inflammatory assistance (i.e. Advil, Aleve, etc.).

2.       Chronic back issue flare ups (common occurrence in the over 50 group).

Due to the fact that an over 50 group of jumper (without the above indicated external factors) remains unavailable, research ended with the following conclusion:

Jumping remains good for the heart, soul, and spirits; however at some point after 50 it is no longer good for the body.  So when your time comes, keep the bottom your skis or board on the snow while you coach, encourage, and watch the young jump.
