要旨：Pick and roll play is a 2 on 2 on ball screen actions that frequently used for creating various offensive opportunities against defensive strategies (Remmert, 2003; Gómez et al., 2015). To perform pick and roll plays success, the coach should consider the effective valuables of pick and roll play to improve the strategic plans (Gómez et al., 2015). Hollins (2003) mentioned that the key to the success of the using a screen is how well player read what defense reacts for the screen. Thus, the aim of this study was to clarify the effectiveness of pick and roll play according to the defensive reactions. The sample was composed of 30 women’s Division I basketball games of 89th Tokai Collegiate Basketball League. The analysis data consist of the variables (pick and roll play defensive reactions and offensive actions). For statistical comparisons, Crosstabulation analysis was used with the chi- square test. Adjusted standardized residual analysis was used to determine which cross-section is responsible for the independence of the valuables. As results, there was a statistical difference between the effectiveness of pick and roll play against the defensive reactions. Pick and roll play was effectively used when defense reacts against pick and roll plays by screen success, whereas, pick and roll play was ineffectively used when defense reacts by slide through and switch (X2=45.274, p<.001). Offensive actions that performed pick and roll play effectively against the defensive reactions were ball handler’s shot against screen success and slide through, ball handler’s drive against switch, ball handler’s drive opposite against fight over, ball handler’s drive opposite + 1 ex against fight over, pass to roll by show and recover, pass to roll +1 ex against show and recover, pass to pop against show and recover and trap, and pass to slip + 1 ex against trap (X2=569.341, p<.001). In conclusion, the main aim of this study was to evaluate the effectiveness of pick and roll play usages against various defensive reactions. The result of this study shows that effective and ineffective pick and roll play usage against defensive reactions and effective offensive action leads to better shot against the defensive reactions. To use pick and roll more efficiently, adequate decisions need to made by ball handler and screener to read and react to the defensive reactions. From the results presented above, performing pick and roll play more efficiently, building the game related situational drills that assume the defensive reactions. Further research is required to clarify the effective offensive pick and roll play actions against the defensive actions with defensive rotations.
