Abstract
This study explores the relationship between the scoring structure and the win or loss of a badminton match, while providing quantitative analytic data using binary entropy to determine the uncertainty of said win or loss. Scoring structure data were collected from the official match records of the top 16 events of the World Badminton Championships from 2006 to 2020 (a total of 10 editions) as collection objects (745 matches and 1,734 sets in all) and were analyzed by means of notational analysis. Our entropy analysis showed that the main factor affecting the certainty of win or loss in men’s singles, men’s doubles and mixed doubles comes from the number of leading points, and in women’s singles and women’s doubles from whether the current point is closer to the match point. Our binary-entropy analysis based on scoring structure showed that, to maintain high uncertainty so that players stay competitive, the scoring points of two sides should differ in less than 5; in addition, the decisive factors for victory strongly depend on gender, also justifying research results of previous studies.
Highlights
Using data analyses of sports competition information, important indicators in athletes’ competition performance can be objectively evaluated, and such data can serve as an important reference for movement analysis, evaluation of techniques and tactics, and decision-making of future training plans and pre-match drawing-up of tactics (Hong and Tong, 2000; Hughes and Franks, 2004; Dieu et al, 2020)
Important findings of this study include that in men’s singles, men’s doubles, and mixed doubles, the main factor affecting the certainty of victory or defeat comes from the number of leading points, while in women’s singles and women’s doubles, whether the first scored point is closer to the match point is most influential
We found in this study that in men’s singles, men’s doubles, and mixed doubles, the certainty affecting the outcome of the match comes from the number of the leading point, while in women’s singles and women’s doubles, the first scored point being closer to the match point has a greater influence
Summary
Using data analyses of sports competition information, important indicators in athletes’ competition performance can be objectively evaluated, and such data can serve as an important reference for movement analysis, evaluation of techniques and tactics, and decision-making of future training plans and pre-match drawing-up of tactics (Hong and Tong, 2000; Hughes and Franks, 2004; Dieu et al, 2020). Many studies have recently been conducted on match time structure, strokes, footwork, and movement of the new badminton competition system (21-points system) (Laffaye et al, 2015; Abdullahi and Coetzee, 2017; Abián-Vicén et al, 2018; Gómez et al, 2019, 2020; Valldecabres et al, 2020), as well as physiological and psychological characteristic performances (Alcock and Cable, 2009; Phomsoupha and Laffaye, 2015), in order to reconstruct the competition information and data analysis results of the new badminton system. The study of badminton from the perspective of scoring status has not yet been seen in the literature
