Long jump: it is so they can clearly see and measure the distance jumped. This is why the sand is smoothed out to show where contact was made with the surface.
High jump: the foam padding provides a soft landing surface to prevent injury.
because it was more easier
so you don't hurt your self
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.
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.
A long jump in track and field is a jumping event where athletes try to jump as far as possible from a takeoff point. The jump is performed by sprinting down a runway and then leaping into a sandpit, with the distance measured from the takeoff point to the closest mark made in the sand by any part of the athlete's body.
Halteres were made of metal or stone, and in Ancient Greece, athletes used them for weight lifting. They also used them when performing the long-jump. The athletes would swing them back and forth to build momentum and then let go of them at the moment they were ready to jump.

The main difference between the events that any auxiliary equipment is not used in the high jump by the athlete. In contrast, the athlete jumps with the pole as an assisting equipment in the pole vault to pass over the bar. All athletes have three attempts per height during the competition.
So they land soflty
The pentathlon is made up of 5 events: 100m hurdles, high jump, long jump, shot put, and the 800m run.
A long jump is typically measured from the takeoff board to the closest point of contact made by the competitor. The distance is then measured in meters or feet.
It varies but the good ones are rubber.
