Research on Relative Space Effectiveness of Badminton Match—Three-Dimensional Space Division of Badminton Court

The three-dimensional space of the badminton court is divided, and with the help of the technique effectiveness calculation formula, it is proposed to analyze the game using relative space effectiveness.Using computer programming technology to solve the calculation deviation caused by taking a balance point slightly lower than the average score rate, making the calculation more accurate and efficient.The case analysis takes the women's singles game as the unit, calculates the effectiveness values of the athletes of the two sides in different spaces, compares the relative space effectiveness of the athletes of both sides, and analyzes the impact of different spaces on the outcome of the game.Research shows that the method of recording data using relative space is reliable and take the relative space effectiveness value of 0.5 as the benchmark to reflect the contribution of space hitting to winning; the difference between the relative space effectiveness of the winner and the loser in the transition space is the largest.Although the loser can occupy a certain advantage in the defensive space, the gap between the effectiveness value in the transition space and the offense space is greater than the winner; the back court space offense effectiveness is the key to the success of the women's singles game.
