Answer» An athlete runs before jumping to gain momentum because it helps in jumping higher and longer because of inertia of motion gained due to the motion. When the athletes jump, they already have a forward motion that would be greater than that of a jump made from standing in one spot. While running, the athlete cannot gain energy or apply larger force because initially he would be rest and while running, he will lose energy.
