Battling midfielders, the derby clash, fighting relegation.

When it comes to sports reporting, the language is infused with more than one combative cliche.

But for the sport of Medieval Combat Fighting - it's less cliche more accurate description.

The sport is growing in popularity all over the world - this report from US television on the American national team gearing up for the world championships.

As you'd expect with a sport which involves running around wearing a metal suit, competitors need to be fit.

Many of those taking part have come from sporting backgrounds like rugby, martial arts and weightlifting.

And you can probably see why high fitness levels are vital when you take a look at this film which shows just how flexible armour was for fighting.

There are strict guidelines for competitors to follow to maintain a safe level playing field.

Fighters compete in individual duels, or team melees. The teams can be three, five, ten or sixteen strong. They're fought over three rounds, each about a minute long, with points awarded for striking or disarming an opponent, or causing them to fall. The armour and weapons used must also be historically compatible. And there's a yellow/red card system for anyone who breaks the rules of engagement.

For the Marshals there are twenty-one pages of rules and regulations to keep tabs on.

"We do go to a lot of trouble to make sure that it's safe, which is why we check all the weapons and armour. if the armour fits correctly they won't actually get hurt by the blows, they just look like they will."
