Secrets of scientific street fights


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

Scientific street fights may sound complicated, but it isn’t. It’s actually quite simple. The best part is, it’s actually easier than learning a martial art. The key is that scientific street fighting eliminates hard-to-do moves in favor of simple techniques that have been proven to work.

So let’s go …

How your body reacts to a street fight:

The first thing a lot of people notice (and what’s most important when it comes to fighting) is that your hands start to shake. It 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 fights? This means fine motor skills stop, things like hand writing or complex martial arts movements (like joint locks that require multiple steps). This is of crucial importance, so be careful.

Why on earth would your body stop fine motor skills when your life is in danger? The point is, your body sacrifices fine motor stills to increase gross (or large) motor strength and speed. These are much bigger things like running, jumping, punching and kicking.

The key to scientific street fighting is understanding this reaction and creating a fighting system that takes full advantage of your stronger and faster gross motor skills. Don’t even waste your time trying to learn complex movements that your body won’t let you use in the heat of the moment.

The loss of fine motor skills is by far the most important part of scientific street fights, but here are a few more reactions that are pretty cool:

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

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

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

Any move or technique that will work 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 become proficient in any self-defense technique.

I’m not saying you’ll master anything in a matter of hours, but you should be able to learn it well within that time. If you can’t, it’s probably fine motor skills that take a long time to learn. These whimsical moves are likely to hurt you when you really need to.

Okay now for the scientific statistics on street fights …

The number one street fight stat that you should learn and use is that the average street fight lasts between 3 and 8 seconds. That’s right. No 5 minute street boxing scene from a movie, only 3 to 8 seconds of ugliness.

So if you focus on science street fighting, it means you need to get on with business fast.

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

The last stat 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 go to the ground.

What does this mean for scientific street fights? Well, first of all, that means you should do your best to end it in under 12 seconds.

Going to the ground greatly increases your chances of being seriously injured. I often tell people that nothing good is happening on the pitch. You’ll get cuts, scratches, shed the skin on your palms, elbows, knees, and face, and remember to get your head stuck in the concrete (and I didn’t even get to the part where passers-by or you assailant friends start kicking you).

The bottom line is, try to end the fight in under 12 seconds by hitting first, using gross motor skills and dirty fighting moves.

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

Okay, here’s a quick rundown of scientific street fights:

  1. Don’t waste your time on fine motor movements, they won’t work in a street fight (that’s not an opinion, it’s a fact).
  2. Use gross motor skills like punches, eye gouging, ear slapping, head kicking, kicking, and only the simplest joint locks.
  3. Always strike first if you want to win a fight.
  4. Most fights end within 8 seconds, so hit him with your meanest barrage of attacks early on (using coarse or simple motor skills of course).
  5. End a fight as quickly as possible to avoid going to the ground.
