Can You ‘Power-Up’ By Screaming During A Violent Encounter?

I was teaching an online class earlier this year and I was asked this question: “If I was being attacked, would I be able to ‘channel’ all my energy, like some professional athletes, and mentally and physically ‘power-up’ to handle the situation with more force?”

I had no idea how to answer that question, so I did research. I found many articles on how letting out a “word, scream or grunt” at a crucial time can be beneficial in a controlled environment, but I could not find any articles specific to using this “power -up” technique when time is of the essence in a violent encounter.

‘Power-Up’ While Exercising or Lifting Heavy Objects

As most of us know, being physically fit is confirmed to help prevent and/or manage heart disease, stroke, diabetes and several cancers. It is also one of the key factors that improves mental stability, and an overall quality of life and well-being. According to CrossMag, the act of yelling while exercising or lifting has many benefits. Please make note that this technique is being used while exercising/lifting and not when time is of the essence. Here are some of the benefits listed:

  • Increase in intensity
    •  Shouting can help you train with more force and intensity; screaming is a release mechanism that allows an athlete to release excess tension and this can lead to greater commitment, stimulating better physical performance.
  • Higher concentration
    •  When performing a demanding exercise or participating in a competition, the noise produced by a scream can divert attention from negative thoughts and external distractions; the act of yelling can become a ritual that helps focus on the task at hand, increasing concentration and determination.
  • Less stress
    •  Yelling during training helps relieve stress and manage frustration better; suppressing the urge to yell when angry is not good.
  • Activates the diaphragm
    • When you throw out a “power-up shout,” you engage your diaphragm muscles, which are responsible for breathing. By engaging these muscles, you can improve your breathing technique and increase oxygen delivery to your muscles. This can help to improve your endurance and overall performance.
  • Enhances mind-muscle connection
    • This is the ability to consciously contract and control your muscles. A well placed “power-up shout” can help you to improve your mind-muscle connection, which increases muscle awareness and activation.
  • Greater strength
    •  The screams that can be heard in gyms aren’t just for attention; Yelling actually helps increase strength.

How About During “Hand to Hand” Training (Striking Martial Arts)?

There are many articles out there that talk about a specific “power-up shout” that is a word (like Kia, Ass, Ch, Ah, Kihap, etc.) that is yelled during specific times in your training. This is usually not emplyed by high level athletes, but it is still common practice. Please make note that this technique is being used while training and not when time is of the essence. For more information about this topic, Akula Taekwondo breaks it down nicely. It lists these benefits to shouting:

  • Increases power
    • Shouting can pretty much guarantee that we are breathing correctly; if reduced hesitation and if channeled well, it increases the most power from your body.
  • Intimidates opponents
    • You have to admit, surprise screams make you jump.
  • Increases confidence
    • A well placed “Kia” places your mind and body in a state that releases anxiety and increases a positive psychological return.
  • Protects Your Body
    •  If you are lucky enough to see a strike coming, a well place “Kia” will tighten your core muscles, release air from your lungs and can even lessen the pain.

Can you ‘Power-Up’ by screaming during a violent encounter?

The answer is (probably) no. I bet you thought it was going to be a yes; in fact, I did too, but after focusing on distance and context, where a power-up scream may be beneficial in a controlled setting, it will not be beneficial when seconds matter and your life is on the line. Think about it, most every point that was made in this article had no time limit, breathing techniques were applied and the goal/end result had nothing to do with lifesaving skills. 

I knew the person that had asked me this question would be reading this post, so I wanted to be 100% comfortable with my decision. I called my friend, Larry Lindemann, who is a lifetime martial artist, combat athlete, SWAT, police and has a degree in Exercise Physiology. I knew he would be able to shed some light and he did not disappoint.

Larry said, “Context and time is the answer here. When you are in an equal initiative, life preservation will not be the focus; but, when you are in an unequal initiative, it is crucial. When engaged in a criminal assault, there is no time to think about ‘powering-up,’ you are ‘in it’ and you have to make the best use of your resources.”

He continued, “Oddly, traditional martial arts focus, almost entirely on equal initiative conflict. Martial arts movies fight scenes are all equal initiative. Criminal assaults, by definition, are unequal. Criminals don’t want fights; they want to use violence to achieve a goal, and therefore, they stack the deck so they will win every time. They use shock and awe, guns, masks and yelling to stack the deck. Even if a victim is armed, the gun is still holstered, and the victim didn’t know if and when the attack was coming. ” 

For clarity, here are the definitions of equal and unequal initiative:

  • Equal initiative – We both know it is going to happen and exactly when it’s going to happen, i.e., boxing, wrestling and honor fights.  
  • Unequal initiative event – Aka, criminal assault. The criminal has the initiative. He decides if and when the attack occurs. Action is faster than reaction, therefore the initiative is unequal … they have it, you don’t.   

When Screaming Works

Larry added, “Screaming can be a valuable offensive tool, but not defensive. Contextually, with space in mind, you can use a scream, aka a verbal flashbang, to get an adrenal response from the other person with the goal to ‘shock’ and startle them. A good scream can also draw attention to the situation from surrounding people. When your primal brain hears someone screaming, your first instinct is to look around.”

Larry brought up another good point and said,  “A criminal has a time limit on the exchange with you. He wants to get ‘paid’ from the time spent with you and when you scream, the clock in his head starts ticking. He will also be concerned on who is watching, and he wans to get in and out with no witnesses.”

I would like thank Larry for the time and energy that he put into this topic and my education. He is an expert in this field and our conversations make me think outside the box.

That confirms it, trying to ‘power-up’ and increase your physical capabilities during an assault will probably be a no-go, but don’t be disappointed because your voice is an amazing self-protection tool. If you have the space, scream at that bad dude and “build a sonic wall,” as Larry would say.
