Re: Backward Roll - Risks and benefits
At the BAF Summer School 2005, Sugawara Sensei introduced a different form of Ushiro Ukemi. This being instead of rolling over your shoulder, you just roll over your back; hitting the mat when you hit the ground and then hitting the mat again when you have rolled over.
If I can remember right he explained that this was much more safer than practicing the normal, standard Ushiro Kaiten Ukemi. Since when practicing technique with power and Uke aiming to do this rolling Ukemi, it can, I would imagine cause some sort of stress on the neck etc. Which is where this would come in?
