How does one explain which lower body submissions (leg locks, heel hooks etc) are allowed or not for the various BJJ divisions?
At the recent Pan Pacs I recall there were four rule-sets used for various divisions:
Children U8, U10 and U12 no submissions whatsoever.
Children U16, Men Woman and Masters White and Blue Belts only upper body submissions (arm, wrist and shoulder).
Then I get confused...
Men, Women and Masters Purple and Brown Belts - upper body subs + knee and ankle hyper extensions?
Men, Women and Masters Black Belts - as per Purple and Browns and ?????
Can anyone help me out here?
