I have watched quite a few clips on Youtube of Yahara Sensei performing Gyaku Tsuki with what I consider an excessive twisting of the hips. Might twisting to this extent cause back problems in later life ? I realise that, as a mere 4th Dan, I might be misunderstanding Yahara Sensei's teachings in some way.
Andy, I know exactly what you are talking about. I was introduced to the same thing when I went on Andre Bertel's seminar, as Yahara and Andre were both students of Asai. And I can tell you Megan & I couldn't walk the next day! We used muscles in our backs that we never knew existed, the pain was extreme. We took lots of drugs and long hot showers the next morning just to get moving again, as we still had another 4hrs of training ahead of us. But as with all disciplines, the more you do it, the appropriate muscles get strong. But in saying that, I am glad my current style engages a 'less is more' policy and my back is diffinately thankful.
First off maybe its not that he over does it...maybe that some of us are under- doing it. I have seen his rotation doing Gyaku zuki and it is pretty much what we try to teach at our clubs and what I do in the basement Dojo ever morning.
Secondly, we may not be physically able to do the same things as others....and some simply dont try! He may have exceptional ability, flexibility and strength and others may have injuries, weaknesses and structural issues that limit their ability....most of which can be trained out of them...some can not.
Lastly, if you do something one way your whole life, and it sticks with you to old age, and others dont and suddenly try they wont be able to do what you do. Its one reason I like to see kids jump into Karate and stay. I am over 40 and my instructor turns 70 this year, we had a 20 and 35 year old join the club a few months back and they were blown away that a 70 year old could do the things he does, and they were not able to do the things that I can do (Splits for example). Its about consistancy and effort.
I dont think Yahara Sensei goes and takes hot showers and drugs after he is done with a class because he is used to it, its part of his physical ability. However, if you were to ask him to do something unique to his body like cricket...maybe that would be different for him and he would need a few pintes, some ASA and a hot shower after...or maybe horse riding..you get my point I hope.
Very much get yer point yer flexible Git! I was with the now famous Richard Heselton and he says that when training at the JKA you are expected to CONSTANTLY push your body. Now he was clear that doesn't mean you have to run aMarathon each day NO - what it means is that you must constantly push for that one millimetre nearer to Excellence in form etc and therefore by training for a lifetime you will get there and thus, in older age - if you have not been scuppered by illness or significant injury - you will get there and still move as freely as a much younger person but BETTER! A journey of ten thousand miles starts with the first step!
it would still be helpful if Andy can direct us to the film he has been watching that led to the post.
Steve - I would post the clip if it was on Youtube or somewhere, but it was sent to me on my Facebook page about a month ago. It was filmed on somebody's video camera. I can't remember who it was who sent it to me.
