Yes, many games make the most of it to show the players the effect of there attacks.

In S&tBK if you swing Caliburn, wherever he cuts leave a white arched line. This is simply for players to clearly see the damage-area of the attack to use on enemies.

It's just the same for Knuckles, his fist glow to look more fierce but not more powerful. But I believe his power increases with his rage.
