Question: is aikido allowed in mma?
Answer: Aikido is NOT banned in the UFC. However some the Osae Waza of Aikido (nikyo and Sankyo) are not allowed in UFC because of the small joint injury it can cause. You won't see Aikido in UFC because the concept of the UFC goes against what Aikido stands for. ... A lot of Aikido moves are based on small-joint locks.
