I wonder how much weight he's gained in the last couple years though.  He used to calculate his body fat because apparently there was a difference in the quality of his jumps when he veered from 4%.  What is several pounds of muscle going to do?  His jumps have looked heavier but I'm not sure how much is just injury vs. adjustment period while training new quads vs. adjusting to a new body composition

Now you've got the physicist in me thinking:

 

1. The more homogenous and solid a rotating object is, the easier it will turn. Therefore, compact muscle and bone, which can be controlled consciously, would offer less resistance than fat, which is a non-rigid and effectively inanimate mass. Think of a glob of jelly clinging to a spoon. If you jerk the spoon, the momentum you impart makes the spoon move quickly, but the jelly doesn't transfer momentum well so it  moves slowly and falls off the spoon. Likewise with human fat. 

 

2. The more muscle fibers, the more power. Therefore a more muscled body can generate greater speed and momentum. It also means Yuzu can resist the centripetal force of the rotations better, which is the force that pulls rotating object outwards. So he can hold a tighter, faster rotation for longer. 

 

3. Higher mass means more power is needed to make the jump. But it also means that it generates more momentum once in motion.

 

4. The distribution of the mass matters and will affect rotational speed and (I'm guessing here) stability in the air (jump position). But I can think of ways in which it benefits as well as ways in which it detracts, so maybe it's a wash? 

 

In short, I think the benefits of having more muscle power outweigh the negatives of being heavier. But Yuzu must be carefully monitoring every aspect of this to make sure it works out.

the things you guys know...I'm kinda speechless but thank you for explaining it in such easy terms.

I think Otonal costume doesn't flatter him around the waist area but if you look at him in his UA gear it's pretty clear he's has wider shoulders and more defined arms and pecs and hopefully as you said this will help.

You're welcome and it's only high school physics. You can  do a couple simple tests with a spinning top or some such object  and try it for yourself. 

 

Yuzu's becoming a regular physics teaching aid. A textbook company should endorse him. :umm::LOL:

When did he do that?!? Is there a video?!? I mean, obviously not the showering, but the showing off his abs part? :redface:

Actually I think he told the photography crew that his waist was insane. This was written I think in Kateigaho feature by the actual crew.

Sadly, no. All we have is the magazine article talking about it.

This happened after his shower when he was choosing between 2 sets of clothes we had laid out for him.

 

“Look look~ My waist, it’s insane* you know”. When we turned around, we saw Hanyu with his shirt scrunched up, showing his waist to all of the staff present.

 

Whaaa– it was so…narrow!! Zero fat. So tight. But it wasn’t just narrow, the muscle bulk was as expected of an athlete! A crazy waist, so envious…There’s no doubt all of the staff there were thinking the same thing (laughs).

These new clips made me absolutely speechless... and the translation adds more nosebleed inducing material.

I can't stop looking at Yuzu showing off his newly gained muscles. :redface:

woooof, very yabai :10742290:

The best thing is the person behind the camera murmuring "ohh...sugoi..." in such a gentle, reverent tone as it zooms in for the Yuzuboobs closeup shot. :xD:

It may be my post in July.  No video, sorry :P

EDIT:  Oh, there were also those who have got their teeth into this article, of course :happy0007:

Thank you! This is very enlightening and entertaining. And provides more nosebleed material. :biggrin:

It's great that Yuzu puts so much thought into how to support his body in the best way possible for those incredible athletic feats. I have a feeling he's much more mature now and is very well aware of the risks. He's working slowly and steadily toward long-term results. I'm keeping my fingers and toes crossed that everything works out for him. :smiley-angelic001: :fingerscrossed:
