Spain's steely roller derby skaters championing inclusivity in sport

BARCELONA : Boasting names like "Femina Morte" and "Mad, Mad Chica," the skaters of Barcelona's Steel Groin (Ingles de Acero) roller derby team are as tough as their names sound.

The fast-paced, full-contact sport played on quad skates and divided into two 30-minutes halves of "jams", each lasting up to two minutes, is growing in popularity around the world and drawing players with its LGBT+ friendly and inclusive ethos.

Roller derby sees teams play five players a side, one of whom is a "jammer", who seeks to pass four blockers from the opposing team as they skate at high speed around an oval track.

The blockers try to stop the jammer while making room for their own jammer.

"I love roller derby because it's a community around the world, where no matter your body, your gender, your sexual orientation you are welcome," said Steel Groin's Marina Quer, aka "Marinaker," who plays as a jammer.

Steel Groin is a team for women and individuals who self-identify as women, in contrast to many sports run on strict gender binary terms.

"Women can be strong, can be violent, can be competitive, can be strategic… and I love that," said Quer, a 30-year-old marketing director.

There are about 25 roller derby teams in Spain and over 1,200 leagues worldwide, mostly in the United States.

The sport's international association, the Women's Flat Track Derby Association (WFTDA) states it is "committed to inclusive and anti-discrimination practices in relation to all transgender women, intersex women, and gender expansive participants, and aims to ensure that all skaters', volunteers', and employees' rights are respected and protected."

Roller derby was developed in the United States in the 1930s. Practiced mainly by women, it enjoyed a revival in the
