Acceptable injury rate?
I was wondering what would be considered an acceptable injury rate in aikido.
I have observed over the past few years one particular person involved in over half a dozen injuries that required medical intervention -- a few shoulder separations (Class III), a concussion, back and knee injuries requiring physical therapy at least, to name a few without providing too much identifying detail. There was only one other injury that required a hospital visit that did not involve this person during this period of time. I'm not talking about tweaks and bruises and accidentally hard atemi. I'm talking about interrupting class to take somebody to the hospital, or the person having to seek trained medical help to alleviate the problem and losing weeks to months of training time as a result of the incident. Ironically the person in common with all these incidents does not escape injury either but still insists that these are an unrelated string of accidents.
Is it reasonable to say that a safety line has been crossed?
