Sprint is mainly divided into three stages: starting, running on the way and sprinting.
The departure process includes three stages: "take your positions", "prepare" and "fire your gun". After hearing the "take your positions" password, squat down, put your hands and fingers together, put your thumb on the back edge of the starting line in a figure of eight, and step on the front and rear starters in turn, with your feet close to the starter and your toes touching the ground. The back and neck are naturally relaxed, the arms are straight and shoulder-width, and the hind legs and knees support the body.
After hearing the "prepare" command, the hips are raised to shoulder height or slightly higher, the shoulders slightly exceed the starting line, the weight mainly falls on the arms and front legs, the front and rear calves tend to be parallel, and the feet touch the pedals near the starter. The whole movement needs coherence, coordination and strength, and attention is highly concentrated.
Finally, when I heard the gunshot, I quickly pushed my hands off the ground and bent my elbows to swing back and forth. My legs slammed on the starter in turn to make my body move forward and upward, and my hind legs quickly bent their knees and swung forward and upward. At the same time, my front legs stretch my hips, knees and ankles quickly and forcefully, pushing my body forward with a greater forward posture.

1896 At the Athens Olympic Games, Thomas Burke, an American track and field athlete, won the 100 meter race with a time of 12 second. This is another victory for him after the 400-meter race.
At that time, the starting postures of sprint competitions were varied, including standing upright, bending over and spreading out hands.
Burke was ridiculed for his weird posture when he started the squat, but in the 100-meter heat, he set the first modern Olympic record in the event with a time of 1 1.8 seconds, and later won the championship in the final. Burke's success has made the track and field circles generally adopt the "squat" starting technology in sprint competitions.
