Judo tournaments are a lot like this until people get more advanced. Very tense, less listening, more power, less finesse. Some of it is just nerves, some of it is level. Some of it is a combination.
Interesting observation. Having worked with two people I knew who were Olympic level Judoka Originally from France immigrated to the US They said exactly the same things feeling at the upper levels the “spirit“ of the art was not there.
They wanted to learn some taiji from me, and were quite surprised they were unable to throw me.
Not saying they couldn’t throw me, just at that time they were unable to...
Judo very honest and straightforward art, develops lots of spirit.
Regarding the clip as you noted the tone is very different.
Having judged push hands competitions in the past.
For me the clips are very similar in technique and application done for the same reasons.
