Wheelchair tennis shares many similarities with the non-disabled type of the tennis, having the same ball, court size and scoring system.
In contrast to traditional tennis, wheelchair tennis players are allowed to bounce the ball twice before returning it. The first bounce must be inside the boundary of the court, but the second can be inside or outside the court.
When serving, players must remain stationary but are allowed one push of their wheelchair before hitting the ball.
Matches are played in a best-of-three-sets format, with tie-breaks deciding sets when necessary.
The sport is divided into men's, women's, and quad divisions. The quad division is for players with impairments affecting three or more limbs.
Alfie Hewett, despite his success, is yet to win a Paralympic gold. He aims to achieve this at Roland Garros, where he has won three singles titles.
Gordon Reid, a 2016 Paralympic gold medalist, also won a bronze in Tokyo and, along with Hewett, is a dominant force in men's doubles.
Belgian athlete Joachim Gerard, a bronze medalist in Rio, is preparing for his fifth Paralympics after recovering from a cardiac arrest suffered during the Tokyo Games.
In the previous Paralympics, British wheelchair tennis players secured four medals, including silvers for Reid, Hewett, Shuker, and Whiley, and bronzes for Reid and Whiley.
As the Paris Paralympics approach, top athletes like Hewett, Reid, and Gerard are expected to be key contenders in their respective categories.
