Scientific street fighting is all about understanding the human body’s physiological response to a fight and understanding the effectiveness of various statistically based street fighting strategies.

Scientific street fights may seem complicated, but they are not. Actually, it is quite simple. The best part is that it is actually easier than learning a martial art. The key is that scientific street fighting eliminates difficult moves to make in favor of simple techniques that have a proven track record of success.

So here we go …

How your body reacts to a street fight:

The first thing many people notice (and the most important thing when it comes to fighting) is that their hands start to shake. This is not a sign that you are afraid; it is your body’s natural reaction to a life threatening situation.

What does this mean for scientific street fighting? It means that fine motor skills are turned off, things like handwriting or complex martial arts movements (like joint locks that require multiple steps). This is of the utmost importance, so pay attention.

Why the hell would her body turn off fine motor skills when her life is threatened? What happens is that your body sacrifices fine motor skills to increase strength and speed in gross (or large) motor skills. These are much more important things like running, jumping, hitting, and kicking.

The key to scientific street fighting is understanding this reaction and creating a fighting system that makes the most of your strongest and fastest gross motor skills. Don’t even waste time trying to learn complex movements that your body won’t allow you to use in the heat of the moment.

Loss of fine motor skills is by far the most important part of scientific street fighting, but here are a few more reactions that are quite interesting:

Your skin will turn pale because your body is restricting blood flow to the skin. This reduces blood loss from superficial cuts and scrapes that you are likely to receive.

To save energy, your brain stops recording so many short-term memories. This is why people often cannot remember exactly what happened after a disaster or fight.

There are a lot of other really cool things your body does to prepare you for a fight, but when it comes to scientific street fighting, the first thing you need to think about is focusing on gross motor skills.

Any move or technique that works well in a street fight should be simple and easy to learn. In fact, it shouldn’t take you more than a few hours to master any self defense technique.

I’m not saying you master anything in a few hours, but you should be able to learn it well in this amount of time. If you can’t, it’s probably based on fine motor skills that take a long time to learn. These graceful moves are likely to hurt you when you really need them.

Okay now for the science statistics of street fights …

The number one street fighting statistic that you should learn and follow is that the average street fight lasts between 3 and 8 seconds. That’s right. There is no 5 minute street boxing scene from any movie, just 3-8 seconds of ugliness.

So if you are going to focus on science street fighting, this means you need to get down to business quickly.

To further illustrate this point, I like to use another statistic. The person who strikes first is more likely to win the street fight. If you haven’t figured it out yet, asking first means that for at least one or two of those 3-8 seconds you’ll be “winning.”

The last statistic is that after 12 seconds the fight will almost always go to the ground. Now most fights never get to this point. 12 seconds is a long time in a street fight, but if it lasts that long, it will crash.

What does this mean for scientific street fighting? Well, first of all, it means that you have to do your best to finish it in less than 12 seconds.

Going to the ground dramatically increases the chances of serious injury. I often tell people that nothing good happens on the ground. You’ll get cuts, scrapes, lose skin on your palms, elbows, knees, and face, and don’t forget your head slammed into concrete (and I didn’t even get to the part where passersby or friendly attackers start kick you).

Simply put, try to finish the fight in under 12 seconds by hitting first, using gross motor skills and dirty fighting moves.

You should also realize that if the fight lasts longer than 11 seconds, you will need to know how to handle yourself on the ground. There are scientific street fighting skills that will dramatically improve your chances of winning on the ground, but I’ll save that for another time.

Okay, here’s a quick review of scientific street fighting:

  1. Don’t waste your time on fine motor skill moves, they won’t work in a street fight (this is not an opinion, this is a fact).
  2. Use gross motor skills such as punching, eye punching, ear slapping, head butting, kicking, and only the simplest joint locks.
  3. Always strike first if you want to win a fight.
  4. Most fights are over in 8 seconds, so hit him with your nastiest barrage of attacks early on (using simple or gross motor skills, of course).
  5. Finish a fight as quickly as possible to avoid going to the ground.
