Background

The run-up device is a track and field run-up device used in various large-scale events.

In the past, sprints were started standing. The australian sprinter, hurel, has been distressed by standing sprint performance. He observed that although Kangaroo dragged a big bag, the abdomen was defecation, but he ran 70 kilometers per hour, and one jump to 12 meters. Sertoli finds that the kangaroo always bends down to get the abdomen close to the ground before jumping, and then starts up once. Surial simulated kangaroo invented a squat start, so he created excellent performance on the olympic games in 1896. Later, many athletes followed. If another athlete buke digs a small shallow pit at the squat place on the starting line, puts one foot into the shallow pit, and pedals the foot during starting, the arrow is generally shot out, and the result that the short run of 100 meters is less than 10 seconds is obtained. Later, all race athletes have used squat starts, and race-aids appear on athletic fields.
