One female judo champion once mentioned in an interview that she sometimes used effective but dishonest tricks to win a competition, and when the reporter asked her to comment further, she said she would 'prod the opponent in the ribs, tickle her along the way.' There wasn't much information about her, except for one blurry photo and that she was in her early twenties by then and lived in Samara, a city on the river Volga in Russia, but it is like documentary evidence that at least one woman in professional wresting used tickling to gain advantage over her opponents.
Another time, a vanilla online discussion turned to the subject of tickling, and one young woman wrote she could never stand being tickled, as it turned her into a tornado of kicking and bucking and flailing around. She wrote that when she was in college, she did some judo: 'I was new in the judo class, and the girl I was wresting with sat on me the way I couldn’t move, so I started to whine that I’m just not strong enough to break the hold. Our coach said nothing; she crouched down next to me and then began tickling me in the ribs, so I wriggled free in no time.'
