What must happen after both teams return to the court post-timeout?

The correct answer emphasizes the procedural requirements following a timeout in volleyball. After a timeout, one crucial step is that both teams must return to the court prepared to continue play. During this phase, substitutes can enter the set as authorized by the coach, which is a critical part of the gameplay dynamics.

When teams return to play, it is natural for coaches to adjust their lineups based on the previous play and the upcoming strategy. Substitutions can bring in fresh players who may execute specific plays better, enhance defensive capabilities, or improve overall team performance.

Other actions can follow after the timeout, but the entry of substitutes is a key element that directly impacts the flow of the game. This requirement prioritizes maintaining continuity in how the game is played, allowing teams to adjust their lineups strategically after the pause.
