 High jump In the high jump, jumpers approach the bar from a level take-off area at least 15 metres long. The round bar is about four metres long, weighing no more than two kilograms and supported by two uprights. The jumpers land on a large, soft foam mattress. Pole vault In the pole vault, vaulters approach on a level runway at least 40m long and take off by placing their poles in a metre-long box sunk into the runway. The walls of the box slope inward and taper toward the far end, guiding the pole toward the stop board at the end, where the box is 20cm deep. The poles are smooth, although perhaps taped to improve grip, and may be as long or thick as desired. The crossbar is similar to the high jump, but 2.25kg due to being longer (4.5m), and the vaulters also land on a soft foam mattress. Long jump and triple jump The takeoff runway is at least 40m long. The foul line is the far side of the 20cm-wide takeoff board (a line of plasticine at the end of the board helps to detect fouls.) , and the jumpers land in a rectangular pit of soft, damp sand. The sand is one to three metres from the board in the long jump and 13m for men, 11m for women in the triple jump to allow the hop and step. Shot, Discus, Hammer, Javelin Strict safety controls are in place for all throwing events. In potentially less controlled events such as the discus and hammer, safety netting surrounds the throwing circle that the projectiles may only fly in the desired direction. |
