(23-7-2021).Researchers from several Spanish universities study entropy in the Badminton game.Work reinforces the idea of the existence of stable space strategies during the parties of this sport.
A team formed by Javier Galeano, professor of the group of complex systems at the Polytechnic University of Madrid, Miguel Ángel Gómez, professor of the Faculty of CC of Physical Activity and Sports (INEF-Madrid) of the UPM, the professor Javier M Javier M.Buldú of the Rey Juan Carlos University, together with the laureate coach of the Spanish Badminton Federation, Fernando Rivas, has developed a study that calculates entropy in the Bádminton matches, both in the positions of hitting and receiving.
In the study of the movement, popularity has gained in recent years what is known as the analysis of entropy, a type of non -linear measure that specifically attends to variability or ´desordden´ of a temporary series.
The Badminton is one of the most popular sports in the world, with more than 200 million players who practice it.
The factors to win a point in Badminton are multiple, which reveals the complexity of this sport.Due to this complexity, the need to use tools based on complex systems analysis methodologies appears.In particular, entropy can be a good approach to better know the intrinsic processes of sport.
In this work, the distribution of the entropy of the hitting areas and the reception areas has been studied, using different measures such as standard entropy and space entropy.
93 tournaments of the women's elite of the Bádminton have been evaluated between 2015 and 2020, including 259 games with a total of 218.081 blows.
To calculate the standard entropy of the hitting positions, the Bádminton court is divided into 12 zones, and the probability distribution of the positions of hitting is calculated finding that the players hit the Badminton flyer at the 4 corners of the field, thetwo closest corners and the two furthest.
Surprisingly, the entropy of the points won and the lost points do not present significant differences.
The study of space entropy shows that the pattern of hitting is among a player who hit randomly and one that would send only to the 4 corners of the field.To understand this problem, a model has been designed that studies the possibility of moving from a player who hits a player from random positions only from 4 corners.
These findings reinforce the idea of the existence of stable space strategies during the Badminton matches, with both players using the field areas in a similar way.The article has been published in Entopy magazine
