Key idea
Categories and Contest Time
Cadet, junior, and senior are event age-group labels; published age rules determine eligibility. A category such as -73 kg has an upper limit of 73 kg; +100 kg denotes the category above 100 kg. The referenced IJF cadet, junior, and senior contests use four minutes of regular time; other event categories can differ. starts or restarts action, pauses it and the clock, and ends the contest. A clock pause does not consume regular contest time.
