By increasing momentum of the trunk, the total momentum of the center of body weight increases. Thus, the main role of the motor transition appears at this stage between the thighs and trunk[15],[16], [17] pointed out that the movement transfers from the thighs smoothly to the trunk to prepare the player to throw the opponent strongly.

It is one of the basic requirements for this part of the skill which is in agreement with what was reported by [18], [19] Then, the player stretches his feet in the phase of kake and turnover of the face in the direction of throwing, which is at the maximum speed in less time, where all forces in the two previous phases turn to serve the motor duty at this stage that should be performed in a flow without cut in performance.

That is consistent with what reported by [15], [20], [17], in that the change required in the speed of performance is not done only if there is the power necessary for this change as well as providing the right time, which leads to the flow in performance and not to be cut.

The highest rate of contribution to the variables of the upper and lower limps in the resultant of total impulse of C. G during Kuzushi phase was the resultant of the trunk impulse and the resultant of the right thigh.

G of body mass during Tsukuri phase was the resultant of the trunk impulse and the resultant of the thighs impulse. Suwari-seoi however can badly hurt your knees if done incorrectly The interesting thing is that this issue somehow seems to have been suddenly generated somewhere.

When I competed, formal competition started at the age of cadettes, which was 11 or 12 years old, I can't exactly remember. There was no competition for younger kids. I have never ever seen or heard about such an injury in those days. My first confrontation was when I had a visitor from Peru who visited a club where I was the junior teacher division year olds and I was teaching suwari-seoi, and his kid was in my group and he went all ballistic that I was teaching such a dangerous technique that would break the neck of everyone.

It was such an incident that raised questions also about the role of the audience or parents during judo classes.

If I recall very well the club's board prohibited the guy from attending the kids classes. Not just me, but also no one else, including the coach of the seniors division at that time had ever heard of such problems.

I also had never hear the term "drop seoi-nage" until I first visited the US. To this day I have no explanation why suddenly after a certain date this technique is considered dangerous, whilst not before, apart from the fact that indeed at a certain date, people started competing from such a young age and at such a level of inexperience, that it is rather the unpreparedness for competition than the technique itself which is dangerous.
