The sport in brief
The aim in judo is to outscore your opponent. There are various ways of scoring points, and throwing your opponent to the floor and pinning them down in submission, known as an ippon, automatically wins the bout.
Contests last five minutes for men, and four for women.
There are seven weight categories for each gender, with a knockout format used unless a lack of entrants prompts a round-robin start.

Ghanaian Emmanuel Nartey is one of only a few competing judoka who also participated at the Games in Manchester 12 years ago.
Many of the squads are depleted as federations focus resources on the World Championships in late August.
What's new for Glasgow 2014?

Survival expert and TV personality Ray Mears may not strike you as much of a sportsman. But he says judo's ideology and entire way of life has influenced him from a very young age. "The lessons of judo are always with me," he explains. "I have tested their veracity in other places and circumstances and never found them lacking."
