The duration of a volleyball match is determined by the number of units played, not by a fixed time. These units, referred to as as a sequence of play, each contribute to the overall outcome. The number needed for victory varies depending on the level of competition and the specific rules in place.
This format promotes strategic gameplay, demanding endurance and adaptability from participating teams. Historically, the adoption of a variable-length match format allowed for a more decisive result, reducing the likelihood of ties and emphasizing consistent performance throughout the competition.
