After a little discussion earlier with a friend of mine, whom is a Judoka, we got talking about the defence application of Judo and whether or not Judo is effective as a self defence technique, i.e. could be used in potentially combative situations on the street. Judo is defined as a "Modern martial art" and after a small amount of research I found that a martial art can be defined as- "any of several Oriental arts of weaponless self-defense" however I doubt that this is entirely accurate.
After being present at a few seminars with Sensei Abernethy and other experienced practioners, it has been discussed in the seminars and lessons that in a street encounter for example it is not effective to employ locks, grabs holds or throws for example, particularly if against two or more opponents.
It may be rather biggoted and opinionated of me to believe that Judo is just locks, grabs, holds and throws, but isn't it, I have noticed that there is much teaching around blocking techniques for example. Also as I discussed before If an encounter is with more than one opponent would Judo be effective, doesn't Judo end primarily on the ground, if groundwork is done on a single opponent the leaves you susceptible to attack from the other. I therefore ask, is there more to Judo than what we see at first glance, or when portrayed through the media in the forms of events such as the Olympics? And would this be an effective means of self defence?
Is there anything suggested in older texts? please note I mean no disrespect to any who practice Judo I was just intrigued.
