Many professional volleyball players begin playing the sport at a young age for several reasons: 1. Skill development: Volleyball requires a unique set of skills such as passing, setting, serving, and spiking. Starting at a young age allows players to develop and refine these skills over time, giving them a competitive edge as they progress in the sport. 2. Physical development: Volleyball is a physically demanding sport that requires strength, agility, and quick reflexes. Starting at a young age allows players to build their physical fitness and coordination, which are essential for success at higher levels of competition.
