Its done to keep the airspeed constant as is required in pattern comps. You do not need full throtal all the time to fly, you need a constant speed, not flat out.

Bingo! It has much more to do with getting a pretty, symmetrical loop with a nice constant speed then it does reducing stress on the airframe. Most sport pilots do eggs, not true loops. Try getting a
round loop with a nice constant speed. Then try to do three of them in a row superimposed on top of eachother. It's not as easy as it looks.
It's even tougher when flying full scale, I've done it. No external reference points plus there is the G-load to contend with. You also hang from the belts at the top of the loop.
I know. I fly full scale.
What aircraft did you fly while doing this?
