When a pilot performs extreme maneuvers, he is experiencing higher "G" forces. 1G is one time gravity 2G two times, etc. This additional gravitationa force pulls on the fluids of the body, including blood, towards the feet, and holds it there, no blood to the brain causes almost immediate blackout. Generally, once the pilot has completed the loop and is flying straight and level, normal blood flow is restored, and everything is o.k. Miltary pilot wear a "G" suit which is designed to allow them to perform high stress maneuvers without blacking out. This suit has built in diaphrams which inflate to trap the blood in the upper torso.

The cause of a blackout is the g force. This is the centrifugal force that occurs during a tight turn. It is called 'g force' because it is the number of times gravity is increased.
It doesn't just affect the pilot either, it also affects the airplane as well.
The link below explains a bit more about g forces.

The risk is due to the change in G-Force, whether it be positive or negative change. I have experienced both negative g's as well as positive g's while in an aircraft that was performing acrobatic moves. It was by far though the most fun I have ever had in an aircraft!!!! My instructor just advised me to remember to breathe normally so I wouldn't pass out.
