Thanks that means a lot to me to read. This year was crazy busy. I competed in American Ninja Warrior, got married (and had a parkour wedding- which took a crazy amount of planning), and spent some time in japan and some time resting from injuries. Glad I can finally get back to it.
I think i subscribed to this channel around 4-6 months ago hoping that it would eventually pick up again as i find the videos you make to be interesting and gives me a different look at training parkour. Very happy to see this is up.
Thank you for this explanation. The jump and roll was nice but I believe the impact can be reduced more by tilting the body more forward/bringing the shoulders more forward, in combination with initiating the roll faster upon landing, and flexing the knees not less than 90 degrees upon impact. Thank you for making these videos.
By teaching this in a way that is not over simplified or overcomplicated I hope to inspire those interested to pursue the field as well, or at least to understand the underlying ideas to have an overall effect on their parkour not just the points I list explicitly. Knowing something someone else doesn't DOES NOT make you better, just different, and reducing those differences by explaining and teaching is how we move forward as a community. *steps off soap box*
Actually this is a point for debate. I left this out because I have asked bio-mechanics experts and a few of the top doctors in the field of joints and they have told me that this is actually a myth and that knees passing 90 on impact wont do any more or less damage to joints or ligaments. At this point I think more research is needed. I am VERY curious on this myself.
It was inevitable. But I'm also glad it's happening, atleast to some extent. The parkour community has been growing so fast in the past decade, new members were arriving faster than they could be "educated". The newcomers created their own terminology (cat pass vs. kong) and went on to incorporate gymnastics to the point where not even the terms "freerunning" and "parkour" are distinct and clear in meaning anymore. Overall, I hope as the growth slows down we will move from "art" to "science".
I do really like your videos, although I'd like to point something out. I've been training for about ten years now, and I've found conclusively through my own training, and training others, that landing on the arch of the foot is never good, as it damages the muscles and can even break bones if performed at higher speeds. The second part of my slight disagreement is simply that through the build-up of muscle in the foot and ankle, and conditioning, impact forces on the ball of the foot, especially in landing on edges like is shown in the video. When hitting the edge, the muscles in the ankles and feet are able to absorb impact and prevent damage to the bones, ligaments, tendons, and muscles in the feet and legs. I've discussed this with biomechanical professionals in my area, and they agree. Your research appears to differ from mine, so I'd like to talk more in-depth some time if you're willing to help me sort it out a bit.
The only thing you are wrong in there is that we disagree... I fully agree with what you are saying. When trying to come to a stop on the edge of the wall however the edge needs to be used to stop for any jump over about 12-13 ft (because friction alone will not stop that much forward momentum). But the contact with the edge should only come AFTER landing on the balls of the feet for the reasons you just described. However as I mention in the video certain upward jumps make it impossible to flex the feet forward far enough in order to put the balls of the feet down (these usually also have less impact anyway) but if you do choose to do these thicker shoes will help avoid injuries.
I see. Well thanks for the reply. It's nice to see someone being active in the community and willing to give a good straight answer to someone with a question. Thanks mate. :)
I'm particularly interested in whether you guys could tell me whether a bad roll results in less g than a good landing without the roll? So would a traceur with a crap roll be better off landing and staying upright if he has a well practiced landing technique?
O_o That's a kind of strange conclusion which I think says more about you than me. This is a problem I often come across so I would like to address it. Teaching and providing new information should never equate to an elitist mindset. Showing off would denote I thought I was better in some way then my audience. I very much don't. I do believe I have a unique skill worth sharing to help other traceurs using the physics knowledge I have acquired in getting my degree.
I knew bad landings sucked, but I never realized just how bad they were. 7g from a five-foot drop? Good to know, since I'm having ACL surgery soon and I'll need to be more careful when I get back to training. Thanks for the information!
Not trying to sound rude but you landed incorrectly with the slap landing. Your arms shouldn't go outside your knees always in even if it's sprawled out more. I don't agree with everything you said in this video fight science did tests on Danny ilabaca and Ryan Doyle about forces and impacts the roll basically channels the impact and dissipates it on the back.
I didn't take it as rude but thank you for the clarification. I place my hands inside the knees (the subject in the video does not.) The hands on the inside is more effective especially when coming to a stop with a slap out, but both are viable in motion at relatively low heights. And Fight Science is god awful and the "scientist" on it doesn't know what she is talking about... I cringed my way through that whole episode. Most of the things she says on that show demonstrate she isn't a real scientist. That whole claim that force dissipates on the back etc is absolutely false and a great example of the fake science on that show... sorry to say its just one more fake thing on TV.
Oh even better... I just did some online research and found the source of the myth. It is indeed a long standing myth created by a single 1961 study which has been since proven to be entirely wrong. YAY for answers! Thanks for the comment!
Hey have you seen that video going around with the guy that jumped off a roof and just bent his legs as he landed? I think you can watch it here: facebook.com/video.php?v=10152452247619021 what are you're thoughts on a landing like that?
If you were at a science fair maybe you'll get good marks? You're on youtube. Was constantly under the impression you were showing off with all those complicated stuff. I could find a simpler way to summarise everything you said.
I'm sorry, i meant, you could've made the language simpler for people everywhere to understand. Not everyone here are scientists too. If you can't put it simply, you do not understand it well enough. Might have been abit too straight, was just trying to feedback, sorry. :P

You're welcome, glad to be back.
Good question. It depends on what part of the roll is bad actually. I will go ahead and edit the part 2 video to cover this though. Thanks for asking.
good stuff. im currently on a mission to improve landings in basketball, specifically dunk landings, and many answers seem to be in parkour

what you're doing is great :) never stop learning
I have been waiting so long for this video! Thank you!

Glad I could help. Good luck with your surgery.
I love these!!!! Parkour + science
great video man!
No dislikes. Good job
Well, look who's here.
I should be updating my log later today after meeting with some other tracuers.

Well it's not especially efficient, but it is damn impressive. That guy has some very strong fast muscles to pull off a landing like that.
i wanna see but the link is broken :(
This looks like the Stratford Library from my neighborhood
It IS the Stratford Library from your neighborhood. :P
Then why are you watching "Parkour Science"?
