Do gymnasts use waist trainer?

Gymnasts should not use waist trainers. The most common reason gymnastic competitors choose to wear a corset is because it provides them with an advantage on the competition floor, acting as leverage when they perform their routines at high velocities and providing support during difficult moves such as backflips or handsprings that could cause injury without this garment depending upon how flexible you are in certain areas of your body which would lead me into speculation about whether these individuals have any kind physical limitations but I won't go beyond that since we're just talking gymastics here.
