Winning a judo match.
In this article we will cover winning a judo match using Osaekomi Waza and either Kansetsu Waza or Shime Waza..
IJF rules state that for a hold to be valid the dominant competitor must control the head and either one or both arms of his opponent.
This can be achieved through the use of either ones arms or legs, additionally the dominantplayer must be lying in either Kesa (sitting), Kami (lying face down) or Ura ( reclining face up),
once any of the criteria is met the hold is considered valid for scoring purposes, influences from sports like wrestling have seen multiple variations enter the tatami which have allowed for
imobilisations using only one arm, at no time however can a hold be valid where UKE is controlled exclusively by the head.
Scoring from Osaekomi.
10 to 19 seconds equals Wazari.
20 seconds equals Ippon
Remember that two Wazaris are equal to an Ippon.
Winning by Kansetsu Waza (armlock) involves the application of pressure to the elbow joint until UKE either taps twice, utters Maitta (I submit) or is incapacitated by the technique.
N.B. Application of pressure to any joint other than the elbow is prohibited.
Winning by Shime Waza (Choke/Strangle) occurs following the application of the technique using the lapel of the jacket where UKE either taps twice or is rendered unconscious.
Submission as the result of either an armlock or choke scores Ippon .
