How It Works:

Men and women each compete in seven events, designated by their upper weight limits (Men: 60kg, 66kg, 73kg, 81kg, 90kg, 100kg, +100kg; Women: 48kg, 52kg, 57kg, 63kg, 70kg, 78kg, +78kg).

Judo was built on three major techniques: throwing (with hand, hip, foot, half-body, and full-body), groundwork (holds, strangulation, locks), and striking (of the upper and lower limbs). The aim in judo is to control the opponent. To do so, athletes apply principles of balance and leverage to throw opponents to the mat on their backs, immobilize opponents on any part of their backs, apply arm-locks to the elbow and choke opponents while avoiding any action that might injure the neck or spine. There is no kicking or punching in judo.

All matches are five minutes long with no designated rest periods, but the clock will stop during breaks in action to ensure that the athletes compete for the full five minutes.

In each weight class, competitors are divided into four pools by draw, although the top eight ranked judokas in each category are seeded to ensure they do not face each other until the round of 16. The four judokas who lose in the quarterfinals get a second chance at the podium through the single-elimination repechage. The winners of the two repechages face the losing semifinalists in the two bronze medal matches while the winning semifinalists compete for gold and silver.

Canada’s Olympic History

Doug Rogers won Canada’s first Olympic judo medal when the sport made its Olympic debut at Tokyo 1964, taking heavyweight silver. Two decades later, Mark Berger added a heavyweight bronze at Los Angeles 1984. Nicolas Gill became Canada’s most successful Olympic judoka with his two medals, bronze at Barcelona 1992 and silver at Sydney 2000, before coaching the country’s most recent Olympic medallist, Antoine Valois-Fortier, who won half-middleweight bronze at London 2012.
