Long Jump - How to Play?
Long jump
The long jump can just as easily be named the “run and jump” or “sprint and jump,” because the actual jump is only part of the process. Yes, there are techniques for pushing off the board, for flying over the pit, and for landing. But these techniques, while important, can only maximize your distance, based on your takeoff speed. Once you’re in the air, there’s only a certain distance you can travel, based on the momentum you gained during the approach run, no matter how good your flight or landing techniques. 토토
Equipment and Long Jump Rules
The sole of a long jumper's shoe can have a maximum thickness of 13 millimeters. Spikes are allowed. The runway must be at least 40 meters long. Competitors may place as many as two location markers on the runway. The jumper's farthest point forward in contact with the take-off board, the toe of the jumper's shoe, must be behind the leading edge of the take-off board. The board itself must be 20 centimeters wide and level with the ground. Somersaults are not permitted. Jumpers must land within the sand pit in the landing area, which may vary in width from 2.75 to 3.0 meters.
How Do They Measure the Long Jump?
Long jumps are measured from the forward edge of the take-off board to the impression in the landing pit closest to the take-off board made by any part of the body of the jumper .Each jump must be completed within one minute from the time the jumper steps onto the runway. Jumps executed with a tailwind or more than two meters per second don't count.
Technique
The first thing a prospective long jumper may learn is that the sport lacks a starting line. Jumpers, of course, must determine their own starting points. The coach will choose the number of strides for the approach run probably based on the jumper’s age—then the jumper may run toward the takeoff board, or may begin at the board and run toward the starting area. In either case, the jumper runs the appropriate number of strides so the coach can determine whether she is striding consistently. Once the jumper learns to stride consistently, the coach can measure the distance she travels in the appropriate number of strides. This distance allows the coach to set the correct starting point.
Beginning jumpers, of course, will be focused on jumping, not the approach run, which may just seem like a preliminary activity—something to get out of the way before the real fun begins. To keep them focused on the approach, therefore, it may be wise to practice the approach run on a track, rather than on a long jump runway. Once the novice jumpers develop a consistent approach run and they’ve learned proper landing technique—let ‘em rip on a real runway. Generally, right-handers will begin the approach by striding with the right foot, and will take off with the left foot.
History
The origins of the long jump can be traced to the Olympics in Ancient Greece, when athletes carried weights in each hand. These were swung forward on take-off and released in the middle of the jump in a bid to increase momentum. The long jump, as we know it today, has been part of the Olympics since the first Games in 1896. The men’s event has seen some long-standing world records by US jumpers. Jesse Owens jumped 8.13m in 1935, a distance that was not exceeded until 1960, and Bob Beamon flew out to 8.90m in the rarefied air of Mexico City at the 1968 Olympic Games. The latter mark stood until Mike Powell beat it with a leap of 8.95m at the 1991 World Championships.
