I've been working with IMMAF for years. For those that don't know, here's some details:
- 3x3 minute rounds, with option for extra round if a draw. Anyone with pro experience is not eligible.
- No elbow/forearm strikes, knees to the head (basically trying to avoid bone on bone contact to mitigate against cuts.) Same reason they wear shin guards
- A few submissions are banned, mainly ones with the risk of serious injury. Heel hooks, twisters, sit-through crucifix, neck cranks and so on
- Colored short sleeve rash guard, shorts and shin pads worn. Red, Blue and Gold (for returning champions)
- Extensive anti-doping protocols, strict backstage monitoring with "commission" equivalent inspectors
- All officials are trained and supervised by Marc Goddard (for refs and judges) and Bob Plant (for cutmen) those that don't perform or have mistakes, need to attend retraining or just not invited back. Quite a few officials have moved up to OneFC, Bellator and UFC.
- Depending on the size of the tournament, 2-4 cages running simultaneously for 5-6 days. 2019 worlds set a record for 126 fights in a single day
- Notable IMMAF vets: Shorty Torres, Sinead Kavanaugh, Micol Di Sengi, Conny Holm, Amanda Ribas, Manon Fiorot, Brenden Allen and Jack Shore. John Kavanaugh recently said the talent has gotten so high, he thinks today's IMMAF champs could compete well against UFCs Top 10-15
We just wrapped up the World Championships in Abu Dhabi a couple days ago. Despite a bunch of athletes and even whole teams not able to attend due to COVID, we still managed to get over 400 athletes from 56 countries.
PS. It's available to watch on PPV, like $10 bucks or something for a whole tournament or $40 bucks a year for everything (which include archive access)
