MMA fans are disgusted by the brutal beating of a female fighter in a Polish inter-gender match.

MMA fans were disgusted to see a female fighter being battered by a man during an inter-gender fight that took place in Poland.

One viewer described the scene to be 'horrific', as the ref had to stop the bout.

Ula Siekacz, an arm wrestler and fitness coach, regularly displays her bulging biceps online.

They were not enough to protect her from Piotrek Muaboy, who claims himself to be '185cm pure sex'.

The online video of the show that took place in a hotel in Czestochowa, Poland was posted.

It shows the couple trading tame blows, before Muaboy strikes a few solid blows at Siekacz.

After she has composed herself, she decides to go for a takedown. But it all goes horribly wrong.

Muaboy turns Siekacz's head and flips her on her back.

She tries to get out of Muaboy's grip and throws several punches that connect with his head.

He manages to ignore them and mount her before it rains punches in.

The ref quickly intervened to stop proceedings, as Siekacz was pinned down and incapable of defending herself.

After the video was posted online, MMA fans rushed for condemnation.

One said, "How can this be sanctioned?" This is horrible."

Another commenter added: "F*** everybody who participated in this." F*** you for posting highlights of it.

Mister B added: "What the unrivalled flack is this?" "

Martin wrote: "This absurdity is unacceptable."

Another said, "This isn't MMA."

This was not the only fight between men and women on the night. Michal Przybylowicz, the Polish Ken Doll, beat Wiktoria Domzalska separately.
