At which Winter Olympics, athletes were required to compete in prone position?

The winter Olympics event "bobsleigh" requires athletes to lie down and compete.

Bobsleigh is a kind of movement that rides or lies on the sled and changes the body posture to control the sled to turn and slide at high speed. Athletes sit on the sledge, push back with their hands with the help of the starting railing to start the sledge.

In the process of sliding, the athlete lies on his back on the sled, pulls the sled belt with one hand, and controls the sled by changing his body posture to make it slide down the ice track quickly. When reaching the finish line, the athlete must be on the sled, otherwise the result will be invalid. Single person needs to skate 4 times, double person needs to skate 2 times, and the results add up. Finally, the one with less time wins.
