Although a legal hold in international wrestling competition, the rarely seen "oil check" apparently is a more common tactic among the Japanese ladies to control their opponent by administering a combination of physical discomfort and intimidation by humiliation.

In "legitimate" freestyle wrestling if you watch closely, especially if you can slow the video speed down, you will see a lot of tit and pussy grabbing going on.  Some of it is unintentional, much of it is blatantly intentional.

I would say this is - sadly - 100% illegal.

The obective in freestyle is to turn your opponent for a pin and the best , short term defence is to get front down on mats and give the opponent your back, which you NEVER,EVER do in grappling.

So its natural to shove your hand betwen her/his legs to try to pull up a nd then roll the defending wrestlers body by brute force. Thats perfect for a quick "oil check" on the way just to remind her you can be nasty too.

Contrary to its squeaky clean , olympic image freestyle can be very rough stuff. One of the top US olympic team women said once " its just fight isnt it"

Well said Tom. It's a tactic that's certainly not limited to Japanese women wrestlers!
