The Effect of Introducing a Smaller and Lighter Basketball on Female Basketball Players' Shot Accuracy

Abstract

Our study examined whether the introduction of a smaller and lighter basketball (no. 6) affected the accuracy of female basketball players’ shots at the basket. The International Basketball Federation (FIBA) introduced a size 6 ball in the 2004/2005 season to improve the efficiency and accuracy of technical elements, primarily shots at the basket. The sample for this study included 573 European female basketball players who were members of national teams that had qualified for the senior women’s European championships in 2001, 2003, 2005 and 2007. A size 7 (larger and heavier) basketball was used by 286 players in 1,870 matches, and a size 6 basketball was used by 287 players in 1,966 matches. The players were categorised into three playing positions: guards, forwards and centres. The results revealed that statistically significant changes by year occurred only in terms of the percentage of successful free throws. With the size 6 basketball, this percentage decreased. Statistically significant differences between the playing positions were observed in terms of the percentage of field goals worth three points (between guards and forwards) and two points (between guards and centres). The results show that the introduction of the size 6 basketball did not lead to improvement in shooting accuracy (the opposite was found for free throws), although the number of three-point shots increased.

Shooting efficiency and structure of shooting in 3 × 3 basketball compared to 5v5 basketball

“…Theoretically, the shooting precision could be influenced by the slightly smaller basketball used by men in 3 × 3 basketball; however, in some previous research, it was shown that small differences in ball size and weight do not affect precision of basketball shooting. 21…”

Successful and Unsuccessful Offensive Sequences Ending in a Shot in Professional and Elite Under-16 Basketball

“…As points in basketball are scored by putting the ball through the basket, shot success is a logical measure for analyzing efficiency ( Simovic et al, 2012 ). Technical-tactical aspects of shooting actions, however, are not easy to analyze ( Podmenik et al, 2012 ), as they are influenced by complex, interacting factors ( Courel et al, 2013 ; Maszczyk et al, 2014 ; Marmarinos et al, 2016 ; Ozakaki and Rodacki, 2012). Attempts have been made to break down this complexity by studying aspects of the game preceding a successful or unsuccessful shot, such as fast breaks ( Refoyo et al, 2009 ), space-time coordination dynamics ( Bourbousson et al, 2010 ), network metrics (Fewel et al, 2012), and interactions between attackers and defenders ( García et al, 2013a ).…”

A Decade of Euroleague Basketball: an Analysis of Trends and Recent Rule Change Effects

“…Overall, there is little research that addresses the rule changes in basketball. Podmenik et al (2012) analyzed shot accuracy of female basketball players before and after a smaller and ligher basketball was introduced in the 2004/05 season (a size 6 ball was introduced instead of a size 7). They did not find any significant differences in field-goal accuracy, but found a significant decrease in free-throw accuracy.…”
