Biomechanics in Parkour
« on: October 19, 2006, 11:11:15 AM »
Next Monday, I have a meeting with the University of Colorado Head Professor of biomechanics. My main intention is to discuss with him some of the dangers of improper parkour techniques, run some tests, and put together and release a valuable reference tool online to show some of the forces we are up against and the importance of training perfect technique at a small scale.

My main focus will be on landings and I know for a fact he has the equipment necessary to run tests on it. I can't guarentee if we will be able to test more but is there anything else anyone here would like me to try to test? Also, any other questions or important topics I should talk with him about?

I think that's a veryg ood idea.  Danno of PKTO did the same thing.  He got something like 600lbs of force from a jump with a PK land and something like 1,000lbs of downward force from a sloppy land.  Crazy, eh?  It'll be good to know your results.

I can't think of anything else you could test, though.  Sorry.

What about the differences between landing on one foot first, both at the same time and quad landing.
What about shock waves through the spine?

Yes, Danno's is what inspired me. However, he never took the time to put together a clear and organizaed report that was easily referred to in the community.

Very true.  This will definitely benefit people.  Great idea, Demon.

you could measure the forces needed in jumping up. like such as how much force it would take to jump a certain hieght or get a certian distance out of a dismounted cat grab. Also you could get the pressure or force needed in different types of wall runs

Sounds good, please post news you get. 

If you can ask the prof. this please.  Overuse of one side of the body and the effects posture short and long term.

If you learn anything about the physics of rolling to spread the kinetic impact of landing across the time axis (sorry, I'm picturing a graph here that models the landing), please let us know!
I give you this:
I will never view my fellow traceurs as a springboard.

All good stuff. I am particurlarly interested in the overuse of one side as well.

Ken, it is Rodger Kram. Same guy? I didn't even think about how you might know but that's cool, I will mention you.

Demon,

I applaud this contribution to the community you are going to make! I can't wait to see the results!

Speaking of landings, measuring the difference transferring energy by slapping the ground makes upon straight-down landings is another idea.

slapping the ground and using your arms in your landing are different things.

sorry, we just had some people pretty forcefully hitting the ground on impact.

Thanks for doing this, it'll be a great help for me personally, trying to get my friends to work on their landings. I can't really think of anything else you could use a biomechanist to solve in parkour moreso than personal observation, if you know what I mean.

All good stuff guys. Keep the ideas coming. This guy is an expert in the field and I am lucky to be getting some of his time. Let's take advantage of it all.

Any chance you can get Lyman to go with you?

I'd like to see max force from different heights, 1 foot, 2, 3 , 4 - up to yu feel comfortable - both with straight leggs (obviously only until well before you feel it's dangerous) and with good glute/ ham absorbtion

I'd also like to see video of you trying to stop your knees from going past 90 since that's the biggest crock and piece of bad info in the PK community, I'm quite sure if you lock your quads to do that, more force and shock will go through your body than if you go to natural flexion.

then I'd like to see (as someone else said) the max f put by you jumping UP to an object, say a 24" box and a 48"
 box

If it's possible to throw the pad on a wall and measure a cat landing that would be cool, measure dx, speed, and see f on the wall.

Jump squats max f

clap pushups, max force on hands
normal pushup max force on hands

pullups max f downward on bar
kipping pullup max force downward on bar

muscleup max force downward on bar
kipping muscleup "

jump staight up as high as possible, knees up, measure landing force


To summarize:

Landing max force, bad form
Landing max f with good absorbtion
landing max f with 1 leg first
landing max f with transfer to roll
landing max f  with trying not to let knees go past 90
landing max f with arm slap

Maybe if you did these all from a standard height, say 4 feet for the comparisons?

Then, if possible, cat leap

jump squat
pushups
pullups

straight jump from standing

Maybe you could test the difference between the angle of a landing and the speed of your take off? I can't really explain it right now because I'm so tired... BRAIN NUMBING!!!! But send me a message if you wanna actually find out what the f*** my babbling ass is talking about....

Good stuff M2. On Monday I will be meeting "Prof. K" (as he signs his email) for the first time. It is just his office hours so I would assume this will be more like a get to know you, learn a littl about parkour, discuss what I want to do. I am not sure when and what exactly we will be able to test (he did say he had equipment to test landing force) but I will keep you all updated on Monday afternoon!
