Article: Imagine that the rules of volleyball forbid the use of hands or arms---that's sepaktakraw . It's a difficult sport, but that isn't stopping the world from picking it up. The court where sepaktakraw is played is the size of one used for badminton doubles. A net and a plastic ball a little larger than a baseball are used. Two teams of three players(left inside, right inside, and server) take their places on either side. A teammate passes the ball to the server who kicks it over the net. Points are scored when the ball touches the court surface on the other side. How sepaktakraw began has been a hot topic. Many Asian cultures once had their own names and rules for it. In Thailand the sport can be found on a famous mural . It was also played to celebrate the writing of the nations' first constitution in 1933. however, various nations discussed to decide the official name and rules in 1960, At last, sepak is a Malay word for "kick", and takraw is Thai for "woven ball".
