No offence but why is Tissier's students' ukemi so special? In my honest opinion they are often quite showy and sometimes impractical.
There is more to ukemi than just fancy flips and somersaults. It's not a show, it is a martial method that saves your body from damage.
I agree completely. What they do has nothing to do with aikido. It is a kind of healthy gymnastic - this guys and girls jump themselves without any reason. But what is worse, such artificial and exaggerated response to a technique has as result that nage learns false technique. When he goes to the other style dojo, where nobody jump for him like that he is completely lost.His techniques are not working even if his partners cooperate, but he has impression that they do full power resistance.And he takes it personaly and gets angry.....
In the other hand, uke is conditioned mentally, that it is safe way to receive a technique. But in reality, it is a true only in Ch.Tissier style. Many styles will not allow such liberty for uke - and for a right reason - from martial point of view such liberty WILL be used by uke against nage.
So such fancy flips become very dangerous for uke, he stops to listen and feel nage's body and can be badly hurt.Doing high flying flip uke can't adapt his position if nage decide to change a technique.
