I notice that “throwers” of the shot put, discus, hammer throw etc. let out a big scream as they finish their throw. How much does it help, is it “necessary”, and would there be a big difference in result if they didn’t scream?
In: Physics
Everything I know is purely anecdotal from years of running track. When throwers throw, they essentially contract a bunch of muscles in their body to propel the object they are throwing forward. This might cause some air to escape their lungs and create the scream sound. Though, some throwers will scream immediately after their throw and I don’t really have any explanation for this other than superstition or habit.
You have 2 muscle types, the big ones you use for lifting and pulling, then you jave another muscle type that I know as twitch muscles.
The twitch muscles are like a spring, when you throw something or punch something at the end of your reach you use the second type of muscle, the letting out noise helps release the spring muscle ‘harder’.
Thus is why big muscles doesn’t mean good puncher, the ones who can create faster speed and use twitch muscles are the real heavy hitters.
Alongside any mechanical things state – it’s additionally some combination of placebo and adrenaline. An almost primal scream, grunt or roar comes naturally when you’re trying to operate at your upper limits. In the same way that screaming seems to reduce your pain if you’ve hurt yourself, again partly due to adrenaline.
Tennis players grunt, people swinging swords probably did a lot of roaring (for other reasons too), someone being nearly crushed by a large object will roar/scream as they’re holding it up
Go to the gym and try to lift the heaviest weight you possibly can (safely) while:
– Exhaling
– Inhaling
Try it four times, with one rep inhale/exhale quickly and one slowly.
Screaming makes your torso more rigid. A more rigid foundation lets your arms and legs be stronger.
