How does screaming help Olympic “throwers”?

Question

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?

Screaming makes your torso more rigid. A more rigid foundation lets your arms and legs be stronger.
