A Visible Analysis Approach for Table Tennis Tactical Benefit

Area of Science:

• Sports Science
• Data Analysis
• Table Tennis

Background:

• Tactics are crucial in table tennis, reflecting player skill and strategy.
• Current tactical evaluation methods are simplistic, hindering nuanced analysis.
• Distinguishing the effectiveness of different table tennis tactics remains challenging.

Purpose of the Study:

• To develop an advanced tactical benefit algorithm for table tennis.
• To create a visible evaluation model for analyzing tactical performance.
• To enhance the ability of coaches and players to identify and compare effective tactics.

Main Methods:

• Analysis of 60 matches from top-25 male, right-handed, shake-hand offensive players.
• Application of a tactical association-mining model and L-shaped curve analysis.
• Development of a visible evaluation model for tactical benefit assessment.

Main Results:

• Identified 37 tactics within the first six strokes using the association-mining model.
• Selected 9 key tactics in specific stroke sequences (1-3, 3-5, 2-4) and 10 tactics in the 4-6 stroke range.
• The visible evaluation model effectively differentiated tactics based on frequency, scoring rate, and benefit.

Conclusions:

• The proposed algorithm and model offer a more sophisticated approach to table tennis tactical analysis.
• The visible evaluation model facilitates quick and effective discovery of tactical distributions and performance metrics.
• This system aids in understanding the advantages and disadvantages of various tactics from multiple dimensions.
