Hey, Attention on Deck!

Hey, NOTHING here is PERSONAL, get over it - Teach Me and I will Learn!

When you begin to feel like you are a tough guy, a warrior, a master of the martial arts or that you have lived a tough life, just take a moment and get some perspective with the following:

I've stopped knives that were coming to disembowel me

I've clawed for my gun while bullets ripped past me

I've dodged as someone tried to put an ax in my skull

I've fought screaming steel and left rubber on the road to avoid death

I've clawed broken glass out of my body after their opening attack failed

I've spit blood and body parts and broke strangle holds before gouging eyes

I've charged into fires, fought through blizzards and run from tornados

I've survived being hunted by gangs, killers and contract killers

The streets were my home, I hunted in the night and was hunted in turn

Please don't brag to me that you're a survivor because someone hit you. And don't tell me how 'tough' you are because of your training. As much as I've been through I know people who have survived much, much worse. - Marc MacYoung

“You should prepare yourself to dedicate at least five or six years to your training and practice to understand the philosophy and physiokinetics of martial arts and karate so that you can understand the true spirit of everything and dedicate your mind, body and spirit to the discipline of the art.” - cejames (note: you are on your own, make sure you get expert hands-on guidance in all things martial and self-defense)

Reaction Time, Movement Time and Response Time

Han'no Jikan [反応時間] (reaction time)
Undo jikan [反応時間] (movement time)
Oto jikan [応答時間] (response time)

Oto jikan or response time is that time comprised of both han'no jikan and undo jikan, i.e. reaction time + movement time. When speaking of the OODA, i.e. observation, orientation, decision, action, model we are actually speaking of the oto jikan or response time.

When speaking of oto jikan we are also speaking of the ability to increase our speed. Often speed is thought of as a muscle response, i.e. the hand moves at the speed of light from a ready to a contact for damage time. It takes more than just that movement and if your muscles are not quick twitch type then it becomes even more important to understand the entire process.

Observation and Orientation are involved with reaction time, i.e. the time to see, hear or feel the stimulus. Part of orientation is to discover the danger/no-danger aspect where you determine if there is a danger to you. The decision comes from the answer to the orientation stage or level. If a decision is made that one is in danger then the person must continue with orientation to choose instinctively the action necessary and then make the decision to use said action which moves us into the action stage.

When the action is implemented you get the response time or oto jikan. This is that physical action time where the brain sends the signal to the body part to be used, the muscles responds and the part then "starts" to move all the way through to the "end" of the move where the fist, foot, etc. makes sudden impact with the targeting.

Then to add to this mix the mind also must orient and decide on targeting which in turns changes which technique or action is taken due to the choice of the targeting. As can be perceived by this exercise the less time spent on the stages or levels of the OODA or the han'no, undo and oto jikan the greater the speed, etc.

How do you reduce reaction time, movement time and overall response time. First, recognize the OODA loop/Oto Jikan model and train/practice to remove as much of the time it takes to achieve completion/success as possible. Start with mind training by achieving a mental ability to self-talk as you train and practice so you can maximize the links from mind to body.

Second, find those sections that are more complex and reduce them back to simplistic and natural or associated closely with natural movements, etc. reducing the time the mind spends on orientation and decision, etc.

Third, take this effort and train in reality so that you can even achieve the ability to "skip" some levels, i.e. for instance when in a social conflict when the adversary is still using his talking stage you act thus skipping your going through the OODA levels to reach action.

I took an on-line test for response time and found that fundamentally if you repetitively test yourself with the same test your reaction, movement and response time's improve. I started out with a time of .263 and after five times ended with a .256. Both are pretty good especially at age fifty-eight/nine. Even this simple and not so scientific analysis tells martial artists that repetitive reality based training can build an overall holistic speed that will benefit in self-defense situations.

Finally, these types of things can also achieve faster response times where one can avoid dangerous scenarios/situations - yes?
