Volleyball is a popular sport played by over 800 million people worldwide. The game was invented in 1895 by William G. Morgan as an indoor sport for older men to play as an alternative to basketball. The objective is for two teams of six players each to volley a ball over a high net, attempting to ground it on the opposing team's side of the court without letting it touch the ground three times. Players rotate positions on the court and follow specific rules regarding serving, touching the net, and returning the ball. Common volleyball injuries can occur from hard spikes or falls, but protective gear and practice can help prevent them.
