The rules of HIT-FC are based upon the Unified Rules of Mixed Martial Arts, supervised by the Shooto Switzerland Commission (SWC). All professional HIT-FC fights are contested over three, five minute rounds (3×5 min), with the exception of five-round championship bouts (5×5 min). There is a one minute rest period in-between rounds. Amateur fights are contested over two, three minute rounds (3×2 min).
HIT-FC only allows competitors to fight in approved shorts, without shoes or any other sort of foot padding. Fighters must use approved light gloves which are at least 4 ounces and allow fingers to grab. Gloves should be supplied by the promoter. No contestant shall supply own gloves for participation.
The referee has the right to stop the fighters and stand them up if they reach a stalemate on the ground (where neither fighter is in a dominant position nor working toward one) after a verbal warning.
A fight can also end in a technical decision, technical draw, disqualification, forfeit or no contest. Only the referee can stop a fight. The referee may take advice from the ringside physician and/or the Commission with respect to the decision to stop a contest. The referee and the ringside physician are the only individuals authorized to enter the ring/fighting area at any time during competition other than the rest periods and subsequent to the contest ending.
If the match reaches its time limit, then the outcome of the bout is determined by the judges. A ten-point must system is used for all HIT-FC fights; the judges score each round and the winner of each receives ten points, the loser nine points or less. If the round is even, both fighters receive ten points. The decision is announced at the end of the match but the judge’s scorecards are not announced.
A decision is made according to the following criteria in this order of priority:
If a fight is stopped on advice of the ring doctor after an accidental but illegal action, e.g., a clash of heads, and the contest is in its second or third round, the match will be decided by the judges using the same criteria. If the fight is stopped in the first round due to an accidental but illegal action, it will be ruled a No Contest. If the illegal action is executed on purpose, it will result in a disqualification.
When a foul is charged, the referee in their discretion may deduct one or more points as a penalty. If a foul incapacitates a fighter, then the match may end in a disqualification if the foul was intentional, or a “no contest” if unintentional. If a foul causes a fighter to be unable to continue later in the bout, it ends with a technical decision win to the injured fighter if the injured fighter is ahead on points, otherwise it is a technical draw.
Facial hair, long nails etc. that may presents any hazard to the safety of the opponent must be removed.
In non-championship fights, there shall be allowed a 1 pound (450g) weigh allowance. In championship fights, the participants must weigh no more than that permitted for the relevant weight division. The organization may also approve catch weight bouts, subject to their review and discretion. Amateur fights: Any strikes on the ground are absolutely prohibited in amateur fights, only grappling techniques can be applied on the ground.
Any contestant who refuses to submit to a post-contest medical examination can be immediately suspended for an indefinite period.
