バスケットボール競技におけるファストブレイク発生条件に関する研究

―アウトレットパスに着目して―

抄録

　This study aimed to clarify the current conditions that lead to the occurrence of fast breaks in basketball by focusing on outlet passes―plays that occur immediately after securing a rebound, one of the main triggers of fast breaks. Specifically, the relationships among the rebound acquisition position, the outlet pass reception position, and the outlet pass reception time were analyzed. The results showed that steals were the most frequent condition leading to fast breaks, followed by rebounds. The Fisher-Freeman-Halton exact test indicated that outlet passes to the ball-side sideline were significantly more frequent when rebounds were obtained near the basket. Furthermore, rebounds secured beyond the free-throw line in the direction of play were significantly associated with outlet passes to the frontcourt. In addition, receiving an outlet pass within two seconds after securing a rebound significantly increased the likelihood of a fast break occurring. These findings suggest that the spatial and temporal characteristics of rebound-to-pass transitions are crucial for initiating successful fast breaks. From a coaching perspective, training that emphasizes quick outlet decisions and awareness of passing lanes may contribute to more effective transition play.
