An athelet always runs before jumping to gain momentum.This helps in jumping higher and longer as the rate of change of momentum becomes less and that is why he can jump higher and longer with the same amount of force.

Its to build up forward momentum so that when they jump they already have a forward motion that would be greater than that of a jump made from standing in one spot. You need forward momentum to get a good long jump and the best way is to have a running start.

Because if they didn't, the highest high jump would be like 5 feet and the longest long jump would be around 7. It would also be more boring
He's generating momentum. The faster he's going when he jumps, the farther he'll be able to jump before gravity brings him back down.
More speed creates more momentum. Which in turn (hopefully) creates a longer jump.
