in judo a submission (win) can be obtained when a strangle or shime-waza technique is used. ‘Shime’ is a Japanese term which implies ‘closing’, in judo there are two forms of closing techniques :
- Choke – pressure is applied to the front of the neck over the wind pipe, to stop breathing and therefore oxygen reaching the lungs (and carbon dioxide leaving the lungs).
- Strangle – pressure is applied to the side of the neck over the carotid arteries to restrict blood flow to the brain
Judoka should recognise when a strangle is on and can not be escaped from and ‘tap up’. It is never ‘good form’ or clever to be strangled into unconsciousness and especially in practice sessions the judoka applying the shime must be aware of the techniques effect and if their partner does not submit then pressure should be released.
