Great Britain wheelchair basketball star Clare Strange has already been to two Paralympics - Sydney in 2000 and Athens in 2004.
The High Wycombe athlete has also played professionally in the Italian League - one of Europe's toughest.
Here she gives a basic guide to one of the fastest growing sports in the world.
GETTING STARTED
Wheelchair basketball is just a fantastic sport.
In 1997 I broke my back in a horse-riding accident and a year later was playing for the GB wheelchair team at the World Championship in Sydney.
Two years after that I was back in Sydney for the Paralympics.
I had never played basketball before but I worked so hard on my physio and playing for the Milton Keynes Aces wheelchair basketball club really helped.
Apart from a few different foul rules because of the wheelchair, it's not that different from able-bodied basketball.
CLASSIFICATION
One of the things that can seem confusing in the game is the points classification system for the players.
Each player is given a points total that is measured by their disability.
These range from a one point player - who is the most disabled and goes up to a 4.5 player, who typically has arthritic knees or is a below the knee amputee.
The points added up for each of the five players that are allowed on the court at any one time must not go over 14.5 so you have to be really careful on who plays.
It's a technical foul if this happens and gives free throws to your opponents, which is not what you want.
WATCH THOSE SUBS
At Sydney, my coach Paul Hudson printed out every possible combination of players so he knew which players he could bring on and when.
The classification system also emphasises the importance of tactics - it is not just a case of making a simple sub like in the able-bodied game.
Some lower pointed players, like the guard, may actually be stronger and quicker and be preferred sometimes but it just depends on the type of player the coach wants.
Basketball's popularity is rising fast in the world and I can't get enough of it. More and more people are playing wheelchair basketball. Why not give it a go.
