 note = {In basketball, fast-break and early-offense are called “progressive plays” because the ball is
continuously advanced from the back-court through the front-court to the basket. In a progressive play,
the preceding play and situation are related to the subsequent play and situation. The plays are not
necessarily chosen freely due to the former play or situation. The plays and situations that are related to each other and are frequently performed in sequence are referred to as nagare in Japanese. This study
investigated the relationship between the preceding and subsequent play and condition in the nagare of
a progressive play in basketball.
We observed and evaluated 658 plays considered either fast-break or early-offense plays. These
plays took place during 12 games between the RF team and 6 other teams in the same bj League (Japanese
Professional Basketball League) held in 2009 and 2010. A total of 17 items, such as “How the opponent’
s ball was taken away,” “The number of defensive players putting pressure on the ball man when
taking the ball,” and “Distance (length) from the end line to the place where the ball was taken away,”
were assessed. As categorical and continuous scales were mixed in the data, we used the t-test for a
correlation coefficient for two continuous variables, the chi-test for two discrete variables, and analysis
of variance for continuous and discrete variables. Considering significant relationships among variables,
we found the following 3 nagare:
When we paid attention to the ball-taking-away method, we found a nagare that was started from
the ball-taking-away by a steal/intercept, through conveying the ball on the center lane by two players
mainly using dribbling and finishing with a lay-up shot under the goal.
When we paid attention to the play just after the ball was taken away, we found a nagare in which
under-goal lay-up shooting was allowed under the conditions that many defensive players put pressure
on the ball man, the distance from the end line to the ball-taking-away place was farther, and the ball
could be conveyed through only the middle lane.
When we noted the duration time from taking the ball to shooting the ball and the ball-conveyed
lane, the following three nagare were detected: In the case of the short ball-conveying time from the
ball-taking-away to the center line and the ball-conveying lanes through only the middle lane, small outnumbered
situations (e.g., 2 to 1 and 3 to 2) appeared and a short duration from center line to shooting
allowed the use of a lay-up shot under the goal; the middle-to-middle ball-conveying allowed for 2-point
shooting by an early offense using the trailers (e.g., 4 to 3 and 5 to 4); and long ball-conveying duration
time from the ball-taking to the center line and ball-conveying middle to middle lines allowed for 3-point
shooting because of loose matching, even though players were not out-numbered (e.g., 4 to 4 or 5 to 5)., 本研究では，ファストブレイクやアーリーオフェンスなどのボールを絶えず前へ進める「前進型プレイ」にお
