In volleyball, a "spike" is a powerful offensive move where a player jumps and hits the ball forcefully over the net with one hand. This technique aims to score points by making the ball land in the opponent's court. A well-executed spike requires coordination, timing, and precision, often following a set from a teammate. It showcases an athlete's power and skill, making it a highlight in any volleyball match, as it plays a crucial role in the game's dynamics.
