Glossary of Judo terminology
Judo contests are currently divided into weight divisions, and the contestants must be weighed prior to competition in order to determine their weight division.
The weigh-in standard varies somewhat from one competition to another. Although all contestants must submit to an official weigh-in, some competitions also permit unofficial weigh-ins on demand. The official weigh-in is performed within a specified time period during which a contestant may be weighed one or more times. Men are weighed while wearing only their uniform pants, and women are weighed while wearing a T-shirt and their uniform pants. Contestants must not be weighed while wearing a bandage supporter, etc.
