Unlike most disabled athletes a deaf professional athlete does not qualify for the paralympics. They have to have more than one disability to qualify for the games. If they want to go to the olympics they have to qualify for the spot with all of the rules and regulations even if they cannot hear the whistle, gun, bell ect.
This is good for athletes that have some hearing and want to participate in the normal Olympics but its not fair that the rules and regulations do not put in account all of the sensory they are missing to become as good of an athlete as other people. Some amazing talent has come from deaf competitors but it is very far and in between that a deaf athlete makes it this far without having to adapt and overcome.
Because of this inequality a new committee called the Deaflympics was invented to give a fair opportunity to all deaf athletes around the world and they just had their 23rd summer game in 2017. https://www.deaflympics.com/games.asp
I think that this genre is not used that often but I think it still fit in the category of artistic expression. They are just trying to find a way to express themselves and this is one way that any person can no matter the disability can do. There is the olympics, special olympics and the paraolympics, so there are many choices and categories one could fit into. To be a deaf or hard of hearing athlete and make it to the olympics, they have to rise above and become the best of the best without one of their five main senses to help them find their equilibrium and learn all of the rules of the game. They would have to learn and understand the cues of the game without being able to actually hear them. This is just one extra hurdle that Deaf and hard of hearing athletes have to overcome to do what they want.
