It doesn't do much to improve your actual striking ability, but it really helps in deal with the way that strikers control a fight and it really helps to understand the control of tempo that happens when both fighters are standing.
One of the traits that alot of people develop in Aikido is the ability to move into an attack, countering it as you move in and applying the takedown. Not only does this scare the crap out of anyone who thinks that they can take you on, but it helps if you want to take control and give you the ability to go the ground whenever you want.
