I really don't know who was she sparring with in that video, but the guy was laughing throughout their "fight". He wasn't even playing with her. He was far less serious than that, and yet she was just completely outmatched. She was struggling, and she was breathless. Completely helpless. And she gave her all.
A woman needs to be extraordinary, unnaturally strong just to outmatch less than average man.
It's just the way it is, was, and always will be when it comes to physical prowess. That's not even a matter of an opinion.
Are you referring to this one?

Because Gegard Mousasi is a 200 lbs high level UFC fighter and black belt judoka, of course she is helpless against him.
But like I said there are sparring videos where she beat non-elite level fighters.

I don't want to derail the thread too much since, well, we are supposed to talk about tickling, but I would still like to answer a few things as a guy who has practiced BJJ and MMA as an hobbyst for a bit years ago.
It's true, men on average are a lot stronger than women.
However in grappling (and by extension in MMA too) technique and skills are supremely important, since arts like Judo and especially Brazilian Jiu-Jitsu are developed specifically to use leverage and proper technique to defeat much larger and stronger but less technical opponents, and they work extremely well for that purpose.
A small and weak but skilled man can beat a much larger and stronger one who is less skilled and experienced, and a skilled woman of average strenght can beat an average untrained man.
The reason why you have weight classes and gender divisions in modern MMA is because fighters are supposed to be on a similar technique and experience level, and between similarly skilled people size, strenght and athleticism are the decisive factors.
On top of that you have to add the fact that elite professional female fighters like Ronda Rousey are usually exceptionally strong and athletic for female standard, and they are even stronger than the average man.
For example an unassuming girl who fight in the 50 kg division like Tecia Torres can deadlift 280 lbs for reps, while most men that don't go to the gym can't even reach 200.
So they are not only stronger, more athletic and with better cardio than a good percentage of men, but they can also beat way stronger and more athletic but much less skilled men thanks to superior technique.
To cut the chase, a woman like Ronda is helpless against elite level male fighters, yes, but she can hold her own against pretty much anyone else and she can easily mop the floor with any man who has no martial art/combat sport training, including the ones that are much bigger and heavier than her (barring extreme outliers/one in a million genetic freaks like a 350 lbs professional strongman or a 270 lbs nfl player)
