The purpose of this study was to clarify strategies of time-out acquisition of volleyball team leaders coaches. We investigated time-outs obtained from 174 volleyball team leaders coaches. We counted the number of times words appeared in time-outs, and made a hierarchical cluster analysis of the frequency of word appearance. We compared word frequency of long-term leaders coaches with that of short-term leaders coaches. Results showed frequently appearing words were“team,”“opponent,” and“consecutive.”We classified frequently appearing words in the clusters depending on whether the score made after timeouts was by the opponent team or a score because of a mistake. The short-term leader coach frequently used the words“team,” “player”and“serve,”while the long-term leader coach frequently used the words“opponent,”“set,”and“flow.”The greatest separation in scores before calling a time-out was three points with both leaders coaches. Results show leaders coaches regarded the state of the opposing team and their own team as important, and leaders coaches called time-outs to change a bad flow when the leader coach’s own team made a mistake, or lost points in succession. The physical condition of the players was also a factor in calling a time-out. Time-outs were also called as a game tactic. A continuous loss of three points was one situation in which a leader coach considered calling a time-out.
