Wrestling, REHS lihng, is a sport in which two opponents try to pin (hold) each other's shoulders to a mat on the floor. Wrestlers use maneuvers called holds to grasp their opponents and control their movements.
Successful wrestling demands strength, speed, coordination, balance, physical conditioning, and knowledge of body leverage. A clever wrestler can often defeat a stronger and heavier opponent.
There are more than 50 kinds of wrestling. Each has its own rules. Some kinds do not require a pin for victory. In Japanese sumo, for example, a wrestler tries to throw his opponent to the ground or force him outside a 15-foot (4.6-meter) circle.
