Of course anyone can get injuried during practice or even break bones. It happens all the time in all sports, it's called "accident" and it's often no one's fault. Another thing is jumper's knee that Yuzu was diagnosed with after the Worlds. It's not a trauma. It's a health condition that is often caused by training errors like for example increase in the frequency of training. http://www.coreconcepts.com.sg/mcr/patellar-tendinitis/
Yuzuru really enjoys to challenge himself but sometimes lost control. I love his endless Samurai Spirit but I was worried so much.
For example, from one Special TV Program of Yuzuru, named 東北未来人, broadcast on 19th Nov 2010.
In the TV program, it's said Yuzuru was practicing 60 quad jumps in one hour a day, almost one minute one quad.
In last year interview, Orser said when he watched Yuzuru practicing at first time, Yuzuru was losing control of practicing quad jumps. I was thinking, oh yes Mr. Orser, this is exactly the problem you have to deal with. And I'm so glad Orser leads Yuzuru to engage more basic skating skills as Yuzuru also admitted in magazine interview he's lack of practicing skating skills.Kato San: After seeing video footage of Yuzuru's practice, I was shocked by his hard training.
Honda San(Takeshi Honda, famous Japanese male skater): Yes, I'm worried. I would say Yuzuru practicing 60 quad jumps are too much, for me, to the most, I used to practice 20 quad jumps a day. 60 quad jumps, is that too much?
Yuzuru: For me, I don't think I jumped too much, I addicted to practice jumps and easily I just forgot how many times I took off anyway. I definitely want to jump
I think Yuzuru should understand it now, over training himself is not such a good idea for his future career. Everything he's been through of FS Worlds 2013 teaches him a life long lesson.
It's great to challenge yourself, but what matters for judges is clean programs (except for "we know who")
It's easier to have same layout in programs every year than trying to ad new jumps and difficulties.
I like to see Yuzuru pushing his limits it's really inspiring and I wish I 'd have at least half of his confidence and willpower, but I also would like to see flawless programs that make you forget you're watching a competition.
If he can actually mix the 2 then he'll be unbeatable. Probably?
