You 'taught yourself Judo'?

Get the fuck out of here.

We've gone through this before. Judo training is primarily just a mat space + bodies, with people shouting random things at you. Especially Japanese style (which Ivaylo can confirm). It's up to you to learn and get better.

Pretty much none of the famous players or nominal coaches from my club had much impact on my understanding on Judo. Plain physics and anatomy did a much better job.

That's not me talking out of my ass. That's fact for the vast majority of players. Most coaches can show you how to do things, like a bag of trips and tricks, but not explain why they work.

I'd get a physicist in here to explain why your self-taught math is wrong but it wouldn't matter.

If I drop a 1kg brick and a 2kg brick from the same height, the 2kg brick hits with twice the force. That means you need to throw the 1kg brick twice as hard to achieve the same effect.

If I throw you and fall on top of you, *we* hit harder than if I throw you and *you* hit the ground. Period.

 

[QingTian]

Define sacrifice throw please.
Im not talking about math. Im talking about your perception of good vs bad judo

The problem is your perception, not mine. You think I am about Japanese vs. non-Japanese Judo, which I am not talking about. I just care about the math.

And that is why there are recreational clubs and highly competitive clubs, such as university, national teams.
I doubt any of the Olympic medalists is self taught...

No.
Im definitely not the only one with this opinion.
National teams do not care about good and bad judo.
They care about effective and non bullshit style

Speaking of bricks, am I talking to one? Your math is incorrect here, again. Wrong formula once again, and the exact proportion depends on height, as your force is only an initial impetus, whereas gravity is constant acceleration.

If you need fancy titles to prove authority, I'm pretty sure both my academic and Judo pedigree is far stronger than yours.

 

[RJ Green]

F = (2mv)/t is the impact force formula yeah?

holding onto someone and falling on them is much easier to do than double the velocity of the throw.

i would mop the fucking mat with you.

My club has produced Olympic medalists, and so I speak from experience. You knew from the day they arrived who was going to potentially be a star. So what does that tell you? That coaching is only able to do so much.

 

[RJ Green]

which club?

Who?

The formula you are stating is m * DELTA v / DELTA t, not mv/t. This formula is for average force in an impact. The delta is change, which is can be approximated as more or less the same for each body is hitting the tatami. Therefore, once again, wrong formula. 1/2 mv^2 provides the force provided, and then you can calculate average force. In any case, if we were to ignore approximation, your formula does not favor a slower throw as there is greater impact time.

It's not easy to double velocity? So when you spike a ball down, you cannot make it double the speed of gravity? Obviously it's harder with higher mass but still that should be easy to visualize.

Maybe you can beat me, maybe you cannot, but how do you know? Or maybe you should focus on getting your black belt first.

 

[QingTian]

Who?

It's not as black and white as you are trying to make me say, but it should be obvious to you that there is a large element of self-teaching in Judo. Many famous players cannot pass on their skills and very few coaches and clubs consistently turn out top players. That means it's up to the individual to work hard and figure out what works for them.

 

[RJ Green]

where do you train, pedant?

 

[QingTian]

where do you train, pedant?

why would I share that with you, so I can waste more time? I'm going to bed.

 

[RJ Green]

thought so.

 

[QingTian]

thought so.

I've got nothing I need to prove. If you don't like the facts you can think whatever you like.

Telling a belligerent online hillbilly where I live is definitely not in my interests.

 

[RJ Green]

or you're a hobbyist keyboard warrior that doesn't train

 

[Deleted member 405583]

Paris grand slam on now!

 

[QingTian]

or you're a hobbyist keyboard warrior that doesn't train

I don't train... not really anymore. My job and family comes before training. I do BJJ more than Judo now even. What does it matter? Let the facts speak for themselves.

I've moved on, and maybe you should too. No matter how real your training is, you're still pajama LARP'ing as little about training Judo matters in the real world. No need to get worked up over Judo arguments.

and there it is
