| 内容記述 | The present study aimed to investigate the comprehensive relationship among various factors influencing successful shots in basketball games and to try to statistically define the degree of difficulty of the shots by using estimates computed from the logistic regression formula. Furthermore, methods evaluating the shooting ability of each player using estimates, ratios of shooting attempts and successful shots according to difficulty, and successful ratios of all shots were developed. The following 15 items regarding shooting conditions for total 1,456 shots in 10 games after the quarter-finals of the 66th All-Japan Collegiate Basketball Championship were recorded: “Score difference;” “Remaining seconds of the shot clock;” “Shooting areas (distance);” “Shooting areas (direction);” “Way of shooting,” “Height of shooting player;” “Play leading up to a shot;” “Screen play conducted before shooting or not;” “Action of player prior to a shot;” “Movement of basketball prior to a shot;” “Distance to defender;” “Ball handling by defender;” “Block shot;” “Foul is committed or not;” and “Height difference between shooter and defender.” Logistic regression analysis was conducted using “Successful shots or not” as a dependent variable and the 15 items stated previously as independent variables, while applying the stepwise method together with a variable-reduction method. As a result, “Shooting areas (distance);” “Shooting areas (direction);” “Screen play conducted before shooting or not;” “Distance to defender;” and “Ball handling by defender” were found to have a significant influence. By quantifying the shooting conditions using the obtained logistic regression formula, “Very tough shot” with estimates less than 0.20; “Tough shot” with estimates equal to or greater than 0.20 and less than 0.25; “Average shot” with estimates equal to or greater than 0.25 and less than 0.40; “Easy shot” with estimates equal to or greater than 0.40 and less than 0.6; and “Very easy shot” with estimates equal to or greater than 0.6 were defined. In addition, it was revealed that the trends and characteristics of successful shots by each player in the games which could not be evaluated only by scores or ratios of successful shots could be understood by using shooting trial ratios according to difficulty level and successful shot ratios. In conclusion, in addition to the knowledge about a trend of shots of teams and/or players, it is considered that an evaluation of shots in games has become possible such as the appropriateness of judgement of whether a shot should be done or not that leads to the cause of a successful or an unsuccessful shot and the characteristics of shooting skills. |
