Re: Defining Kokyu
Many professional athletes study Aikido and/or it's principles. There is a notable Japanese baseball player who studied Aikido with Osensei for the purpose of improving his batting skills. I am not convinced that just because athletes utilize an Aikido principle, that principle ceases to become remarkable. Kokyunage is a catch-all technique name. Any technique that is not an obvious variation of a core technique is usually referred to as kokyunage. Indeed all Aikido techniques utilize breath power, and I do not believe that kokyu nage either uses kokyu more than other throws, or that it uses kokyu exclusively, ignoring other Aikido principles. Saying that we mis-define "kokyu" because kokyunage more than just breath power is like saying that we mis-define "irimi" because iriminage is more than just stepping forward.
