I was just curious as to how dangerous it can get in class. The worst I've had is a sore wrist that literally lasted for 2 years(the guy that did it to me is sensei kevin blok) when he was showing my partner a wrist lock. The worst i've seen happen to someone else is a sprained back and a really bad toe stub.

Ive seen somone get a torn ligament in their foot when somebody got thrown on it at crowded seminar, also I saw a beginner fall over badly and smash their nose flat during a badly executed ukemi from kaitenage.

I have gotten wrist injuries. Currently have one that I got about a year ago during a test from a good shihonage. I think the worst injury we have had in aikido is of course the deaths. I belive the count is up to around 3 or 4 since the end of WWII. O sensei himself injured people and even accidentally killed ukes. Ninjasaurus I feal for you Blok Sensei has very strong throws.

I was mistaken it was 7 from 1972 to 1985. http://www.aikidojournal.com/images/articles/injuries.gif.
I apologize for my mistake.

Very interesting. Seems as though all of the deaths except one were caused by head trauma. I would still like to see any evidence that Ueshiba himself caused the death of other people.

It also seems that these people were doing large numbers of breakfalls, is this normal during an aikido class? I have no knowledge, so I am just curious.

breakfalling is a big part of Aikido, whether we like it or not =]

though i my self have only been in the dojo a couple of months i have a small grasp of breakfalls and they are heavily rellied upon so as to avoid injury during throws with highly skilled sempai

i have to admit though that sometimes out of no where one can beautifuly do a breakfall and not realize what the crap just happend.

i can do breakfallz from atelast 10 feet in the air and im not lying itz lal about turning downward momentum in2 horizontal momentum and spreading the impact out across the entire body that can handle impact. lotz of timez we have the 7 ft guy in my class throw me as high as he can when we do demoz and even tho it lookz fun 4 him and the poeple watching im the 1 having ht emost fun cuz it feelz like u flying

i heard of people being killed on the streetz by shiho nage cuz their head slamz in2 the ground but idk wut is the worst taken in aikido practice

In aikido classes I've personally had a dislocated shoulder, knee and wrist (all separate occassions). The shoulder and knee were from my own sloppy ukemi, the wrist should have been avoided. I've also seen a broken toe and a broken wrist. This is in addition to countless bruises and sore joints.

In other MA classes I've had my nose broken twice, seen cracked ribs and again, bruises, cuts scrapes etc....
