Snap, crackle, and pop… ow, ow, ow

Triceps brachii muscleEarlier this week when I was leading an aikido class, I started to feel pain on my elbow without any apparent cause. The pain continued and when I started thinking what could cause it, I remembered that during the previous day one shihonage had felt uncomfortable and I think that just manifested the day after. The injury occurred when I had been in the front of the class, being the punching bag for shihonage. I kept taking high ukemis instead of ushiro ukemis because the class lead had a confidant throw and I suppose I wanted to show off a bit too. Silly when you think about it, taking high ukemis when you don’t have to, but it feels good to slam on the tatami and it does release the lock on your elbow immediately.

The actual injury came about later on when I asked the class lead about something his taisabaki during the initial entry, and he showed to me. I think I was concentrating on the answer too much, as when he threw me again, I didn’t take a high fall, but rather an ushiro ukemi but had my had in the same position as in high falls. That is, a tad too far from my shoulder. That allowed the nage to execute the throw, but because of the distance my body didn’t have enough time react. The twist on my elbow was not at all bad, it just felt a bit uncomfortable and didn’t notice it at all until the next day when. The exact pain point is in the medial head of the triceps brachii, or at least that’s what I think. I don’t remember pulling a muscle like this before in shihonage, but I’m quite sure I have as this feels like something that would happen every once in a while. A harmless pull that you forget the next day.

Lateral meniscusDuring my 10 year aikido study, I’ve sustained two injuries that have forced for me to take a 4-6 month break, both to my knees. The first time, about the time when I had 3rd kyu, I tore my meniscus on the outside of my right knee. The details have started to escape me, but I think I tried to take a high fall from a kotegaeshi and got up with the momentum of the throw with my sideways. So it was actually the getting up that tore it, not the landing. The knee had to be operated on and I had to recover for half a year. However, now the knee is totally symptomless so it was a break worth taking.

The second time I had to take a break as just a severe pull on the tendons on the outside of my left knee. I healed on its own, but it did take some time to be pain free. That one was a shihonage with a high fall. I didn’t expect it at all and I did the worst thing you can do during an aerial exercise: I stiffened my body. That caused me to land with my foot touching the tatami first, not my side with the free hand making the initial contact. I don’t know if that mistake taught me anything directly, but it at least gave me first hand knowledge that when taking high falls you need to make like a wet dishcloth. Because you don’t always know in advance that nage is going to throw you high, I think the skill is in being able to switch from a steel spring (attack) to a wet rag (receive) without thinking. Is that then a part of trying to attain mushin no shin?

Kyu-graduointitekniikat

Kiinnostuksesta tein taulukon aikidon kyu-graduoinneissa vaadituista tekniikoista. Sarakkeissa on hyökkäysmuodot, riveillä tekniikka; soluissa on listattu missä kokeessa tekniikka kysytään ja mikä waza on kyseessä. Esimerkiksi, “U3″ tarkoittaa ushirowazasta tehtyä tekniikkaa 3. kyun kokeessa, tai “T1o” tachiwazasta 1. kyun kokeessa, vain omoto-muoto.

Ant RELAX NG schema

I use oXygen to edit Ant build files and it uses a DTD for the schema. While that works well, the DTD has a few bugs and AFAICT does not support Ant 1.7. So, I wrote a RELAX NG schema for Ant.

The choice between schema languages was easy, RELAX NG has everything I need and is pleasant to write. In addition, oXygen can use the documentation in the schema, so all the better. I used Trang to convert the original DTD to RELAX NG, then just edited the filed manually and occasionally with XSLT.

The code is hosted at GitHub, licensed under GPL. It’s very much a work in progress, but it works for me.

“So, we meet again”

Lead a normal aikido class today, substituting for… umm… I don’t actually know I who I was substituting, Saturday classes are lead by three different people. I was once again reminded of the feeling you get when you’re leading a class and one of your teachers is there. I always get this uncomfortable feeling that I’m saying something wrong, that my theory on that specific technique is complete rubbish. It’s clear to me that people approach techniques differently, depending on their experience, size, interests and so forth. Still, even after being told that it’s more important that I have a consistent picture in my head, I don’t want to say anything that my teachers wouldn’t say themselves.

Anyhoo, ‘yey me’ is in order. Today I actually managed to execute a kotegaeshi I was happy with. A kotegaeshi that felt like uke was thrown because of correct timing and position. While I don’t think there is a single aikido technique that is ‘easy’, kotegaeshi has for the last few years been the one that is the most challenging. My archnemesis. I believe my problems with it are mostly due to incorrect timing. For ‘hard’ throws that have a sharp angle, my throw is always late. Uke regains balance and then it’s just… too late. Then, for for those forms that use more distance between uke and nage, with the contact being like a rubber band, my timing is too early and that that leads to me trying to force uke to fall. Grr, so annyoing.

What was different today? Well, I took my time. Or rather, gave uke the time they need. I think the reason has been that I don’t trust the uke to turn and return, so that I can continue guiding them down and out. But why wouldn’t they, they’ve attacked me and will continue if they can. So one should be able to wait for the uke, and try achieve the feeling of ‘doing together’ as opposed to ‘you fly through the air and I stand here’. Another key was that I positioned myself differently, so that I could guide uke right up to the moment I actually did the throw. Position and timing are always linked together, change one and you have to adjust the other to match. Today I got those to working together. Maybe there’s hope after all. I just have to work on it and occasionally remind myself of the contradictory nature of kotegaeshi: it has very little to do with turning the wrist in.

Curse of the Homophones

Years ago I studied Japanese. I had classes only once a week and the teaching methods were targeted for the lazy, so I never did actually learn it and stopped after few years. Still, it gave me enough knowledge that I should have solved the question I’ve had for years now, a problem I had with some aikido technique names. This weekend I attended Endo Shihan’s (遠藤征四郎) aikido seminar and while listening to the interpreter, it all fit together.

Ever since I started aikido, I didn’t understand the logic behind the terms katatedori, katadori etc.; one hand grab and shoulder grab. I though kata in both terms was the same word, that literal translation of katadori was “single grab” but as a compound it meant “shoulder grab”. Well, no. They are two different words and just share pronunciation. Or actually three different words.

shoulder
single
form

It’s probably been clear for everyone else since the dawn of time, but for me only now I’ve understood what the words actually are. Lesson to be learned? Never rely on romaji alone, always read the kanjis too. Even if you don’t understand a stroke you’re reading.

No wonder I’ve always preferred morotedori (諸手取) to katateryotedori (片手両手取).
