Defensive Formations of Elite Men’s Teams against In- and Out-of-Systems in Volleyball The purpose of this study was to investigate defensive formations of elite men’s teams in volleyball. 200 occurrences of defensive formations in 6 games (Argentina vs Cuba, Poland vs Iran, Serbia vs Japan, Iran vs Argentina, Cuba vs Serbia, and Poland vs Japan) from the FIVB Men's World Cup Japan 2011 were analyzed by the Direct Linear Transformation Method. The results were as follows: (1) When the setter contacted the ball, there were no differences in defensive formations against any kind of attack. (2) Against quick attacks, there were no differences in defensive formations between the moment the setter contacted the ball and the spiker hit the ball. Against pipe attacks, back players moved back slightly. Defensive formations against attacks from the central zone (quick attacks and pipe) were 1-3 (one block and 3 diggers) at the moment the spiker hit the ball. (3) Defensive formations against side attacks were 2-4 (double block and 4 diggers) at the moment the spiker hit the ball. (4) In the top level of men’s volleyball, it is difficult to make double blocks against side attacks because the duration of the combination attacks (the time from when the setter released the ball to when the side attacker hit the ball) was approximately 1 second. (5) Against left (right) side attacks with combination attacks, left (right)-back players moved to the middle of the court, right (left)-back players moved to the sides of the court, and middle-back players moved to both sides between the moment the setter contacted the ball and the spiker hit the ball.
