In the past, sprints were started standing. She rill, an australian sprint, has been distressed by the failure to stop a sprint performance. Although he observed that kangaroo dragged a big bag and stooped in the abdomen, he could run for more than 70 kilometers per hour and jump for 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. Squat a kangaroo in senire invented a squat start, so he created superior performance on the olympic games of 1896. Later, many athletes followed. If another athlete cuffer digs a small shallow pit at the squat place on the starting line, puts one foot in the shallow pit, and kicks the foot when starting, so that the arrow is generally shot out, and the score of less than 10 seconds of short-distance running of 100 meters is obtained. Later, all race athletes have used squat starts, and race-aids appear on athletic fields.
