If I were to guess, establishing a nice aerobic base and HIIT employed sparingly would be the ticket.
Makes sense for MMA since they have to be conditioned to get through a full round. Aikido is different in that the most we have to go through is 20 to 30 seconds, and that's against multiple attackers. What's most typical in class is taking on an attacker four times in quick succession, then taking your turn as the attacker and getting thrown and getting back up four times.
