Re: Biomechanics of simple throwing
Dropped offline for a bit and now playing catchup. Some random thoughts
I think for me what looking at the biomechanics has been most useful is in helping see things another way. Its true there is nothing new under the sun and so Kuzushi in Judo kata, sumo play, aikido kata and even the systema seminar i went to today all are ways to learn balance taking, perhaps some sometimes the packaging can get in the way and an alternate reductionist view like biomechanics can be helpful. FWIW I learnt aikiage from 2 different DR lineages, they looked different but the same principles (toppling) seemed to be there.
To follow up on Hugh's point, ultimately this thinking (biomechanics) can be limiting yes - but it can be helpful along the way in pointing the way forward. perhaps by getting the mundane mechanics out of the way, perhaps by rev elating things we don't know.
e..g the work with the pressure force plate to me was a revelation because balance was taken before uke could perceive their balance was taken. This hints at the perceptual stuff well beyond the biomechanics and says to me ...yes this is something to pursue to get a bit further. I'm not sure how a controlled experiment could be done, but it bears thinking about - in the mean time uke-nage and traditional training is that controlled experiment perhaps.
oops kids are home, time to run...
