Too dangerous for children?
I need some help.
I want to know if there are techniques that are too dangerous to teach to children, and if so, to what ages.
I'm looking for resources based on medical research, such as something that indicates that kote gaeshi is not safe for children because of the risk of damaging joints which have not matured to a necessary degree.
I have heard views on this by various senseis. Some who condone certain techniques, and others who assure me of the safety. What I _CAN'T_ find is documentation from a pediatric orthopedic perspective, if there even IS one.
Can anyone direct me to a documented resource?
