Gravity, Speed and Acceleration

Continuing our discussion series, Pose Method creator Dr. Nicholas Romanov discusses gravity, speed and acceleration and how these concepts relate to Pose, a method of teaching sport-specific techniques.

Through mathematics, Romanov has determined that the body is falling at its maximum acceleration when tilted at an angle of 22.5 degrees. This is the point at which the “vertical direction of (the) body-weight vector becomes dominating.” He defines the terms “acceleration” and “speed” and explains their interactions.

“Gravity gives us (an) incredible amount of acceleration,” he says; however, the doctor believes we still don’t fully comprehend it or utilize it.

“In classical biomechanics, running was understood like rotation is a consequence of horizontal movement. In Pose concept, it’s opposite: rotation is creating horizontal velocity,” Romanov says.

According to the doctor, gravity is the only force that can increase rotational movement, and the only way to increase rotational speed is by increasing the magnitude of the angle of your fall to a maximum of 22.5 degrees while moving.

I don't think I'll ever get it until I truly dare to lean forward.

In the meantime, and I'm not entirely joking here, this would seem to be one of the best videos to illustrate the principle - though they do stretch the 22.5 degree limit.

Safe for work, family; the best posing is all within the first 40 seconds.

First time I have ever heard anyone outside the aerospace community talk about rotational kinematics....but it definately adds understanding to the topic.

Well, I have to humbly admit, the more I listen to this man, the less I understand his "scientific" arguments... and I am a physics engineer, so I *should* be able to make some sense of it all.

He uses all the buzzwords (gravity, speed, acceleration, etc), but the overall explanation makes no sense to me. Maybe it's the langage barrier (english being a second language for both of us)?

Anybody knows of any peer-reviewed articles on the POSE method?

(Note: I'm not denying that the method works, I'm just worried that somebody is trying to give it a false legitimacy through a scientific-sounding discourse.)

I cannot for the life of me understand why this video is posted. It either is jargon-filled nonsense, or far too technical for understanding by the vast majority of viewers.

No disrespect intended to Dr. Romanov, but I would like to be able to watch his videos and get some concrete advice for improving one's POSE technique. By contrast, when I watch Coach Burgener I always come away with a few new tips or insights about lifting that I can take to the gym that day. In the past I've thought that perhaps I simply lacked the scientific background to comprehend what Dr. Romanov is saying, so it concerns me a little to read a post like #3 above.

In my opinion there is a difference between training videos and theoretic(science) videos like this one. This series with Dr. Romanov is a science series and you might learn something about the theory of Pose watching them. If on the other hand you want a training video with drills and demonstrations you should watch some of the earlier videos with Dr. Romanov in here or the Brian McKensie videos...

Why would you question the videos for being to scientific for the vast majority to understand? do you also think HQ should not program a 300 pound Deadlift because 80% cant lift that much?
If you are not into the theory of Pose, Dont watch the videos. Plain simple.

(Pardon my english, its not my first language either)

I want to see the formulas! So most if people would tune out, I won't...

I agree. I'd like to see formulas, an illustration on the whiteboard, and citation of peer-reviewed articles covering research to support these statements. I'd also like to see just how applicable these concepts are to different body types since Dr. Romanov mentioned the word "theoretically".

Fascinating! Very interesting how he says we all reach max speed after 5-6 seconds of running. Perhaps I should be doing more 5-10 second explosive sprints with lots of rest... sounds easier than Tabata :). Maybe that is why Tabatas are so effective. I am no physicist but I see no need for a formula. This is what I got from the video. If we lean more than 22.5 degrees we will fall, faceplant, kiss the asphalt. Maintaining a 22.5 degree lean necessitates a cadence of 300 steps per minute and would produce a 100m time of 6.7 (obviously hasn't happened yet). It makes sense to me and I can dig it. This is my favorite Romanov video yet.

I also can't help but notice that 22.5 is exactly half of 45, which is the best possible accelerating angle from rest, which makes sense. If you fire a bottle rocket, it goes the furthest at a 45 degree launch, ignoring wind and all that.

There must be some simple truth that currently eludes me- half way to horizontal is 45... and half way to 45 is 22.5, the greatest angle to maintain a speed. Why is this?
