Not telling anyone anything they don't already know but just a warning and reminder for those of us that have kids in Martial arts or teach kids. A couple weeks ago before a wrestling match I had my 7 year old Sayer working with a 8 or 9 year old in the club that is very good at wrestling (his dad did it as a kid and they have a mat at home, the two brothers train all the time, and he's been at it since he was 5). His dad and I have them paired up because they make good partners and his son can teach Sayer some things because he is learning how to wrestle. I was nearby watching when after awhile of the boy trying to teach Sayer things says, "ok, I can show you things too, try to punch me like this" and demonstrates a Tski to the gut. At the time I didn't think much of it or say anything because I thought that he knew better because I thought that he knew better not to do the full technique to someone that does not know what is coming and how to take the fall (I have told him this and when he wants to show me something he always stops at that point when we are off the mat anyway). Well you know what happened next, to my surprise was a FULL demonstration minus the pin of Kotegeashi (for those of you that don't know young kids aren't taught wrist locks and most pins until they are 15-16 years old for the safety of there joints).
The boy did a flip that looked like something from the movie best of the best 2, got up and said "I think you hurt my wrist".
After checking the range of motion palpating and, messaging it for a bit it seemed ok and he wrestled and did well all day with it, but it was a little scary. In fact I think it would have been much worse if he were not a good wrestler and in good shape. Now I know this was all a natural thing for boys this age to do but I thought he knew better and I was wrong, so just a warning to tell them again and again.
