Principles of Judo stay true through all levels.
When coaching at a higher level, I coach with an assumed knowledge (assuming the athletes I am working with know & understand certain principles depending on their level). This initially saves time and means as a group we can start working on more level specific ideas from the outset.
When coaching beginners and younger athletes you are not able to coach with an assumed knowledge as the foundations need to be laid. - This is my job!
I have created a playlist to try to illustrate how I have taken a principle of Judo, developed drills around it and created a framework in which coaches could use at their club (these are below).
I have discussed the importance of structure when doing Judo (for attack & defence) and how stance, posture and gripping is integral. I have also discussed the importance of creating movement to throw.
These tutorials take a simple movement with a hoop to creating movement to improve gripping and throwing with Tai O Toshi, Ko Uchi Gari and Sasae Tsuri Komi Ashi.
Here are the two tutorials; first looking at basic movement patterns and the principle, the second looking at how to continue this with Black belts and competition fighters.
