What is Blocking (Volleyball)?

The act of deflecting an attack at the net — measured in blocks per set.

Last updated: 3 October 2026

Reviewed by Jordan Morley, FA Level 2 Football Coach

A block occurs when a defending player (or players) contact the ball above the net to deflect or terminate an opponent’s attack. A solo block wins the point outright; a block assist deflects the ball for the back row to dig. Blocks per set is the standard measure: above 1.0 per set is strong for a middle blocker. Net touches and reaching-over errors count against blocking efficiency. Top middle blockers combine high block rate with low error rate.

Key points
  • 1.0+ blocks per set = strong for a middle
  • Solo block = immediate point
  • Block assist creates a dig opportunity
  • Net errors count against efficiency

In practice

Blocking technique varies significantly by sport — a volleyball block aims to redirect the ball straight down with hands timed to the hitter's swing, while an American football block aims to control an opponent's body position using leverage and footwork rather than hitting through them, which is why blocking is taught as a highly technical, heavily drilled skill rather than just physical strength.

FAQ

Is blocking more about strength or technique?

Technique and timing matter at least as much as raw strength in most sports — poor footwork or mistimed jump/hand positioning undermines even a physically strong player's blocking effectiveness.

Does blocking rules differ much between sports?

Significantly — volleyball blocking has specific rules about net contact and timing, while football blocking has detailed rules about hand placement and which defenders can be blocked below the waist.
