Coaches shout. Mainly to make you listen and focus your attention.

Our teams coaches shout to us during training and during games. You wouldn't hear them other wise. Most often it's to tell you to work harder or during a game to get you to move to where they want you or if players on the other team are near and focus you on dealing with the challenge at hand.

In some sports like ice skating and gymnast the coaches in the past would be overly aggressive and just nasty to the girls. That is uncalled for but in team sports it is very helpful.
