Tennis 2.0 : Data, a weapon of mass progression

Share :

Data is used on a daily basis on the ATP and WTA tours. It brings a real added-value to pro players.

This second article (first one is available here) provides a detailed picture of the data that you can look at.

First, I would like to explain how data is collected. Data can be collected manually by statisticians, (a statistician has a box, and he presses a specific button if there is a winner forehand, a backhand, a first serve etc.). Data can also be collected by electronic systems. Those systems were built from algorithms and they are equipped with radars. Therefore, electronic systems extract data of the matches (an algorithm is a finite set of operations and instructions providing a numerical result).

Coaches’ and players’ needs can be specific. Data can be more general or more specific in order to cater to their specific needs. That data helps players to analyze the match and to prepare for their future matches.

Global data is essential to analyze a match

At the end of each set and match, viewers can see data organized in a table. Those data are provided by statisticians, who are on the court.

=> The start of points. On the professional tour, serve and return are very important. Those parts of the game could give player a significant advantage. For that reason, players review serve and return data before and after each match.

Detailed data, essential to analyze a match

There are different ways of presenting detailed data. With those stats, coaches and players know exactly what they are going to work on during training.

These boards of analysis consider additional information as the number and the proportion of return point won, top speed of serve or number of serve and volley.

Numerical entries could also give interesting information.
That data is collected with algorithms by radars. They can calculate, for example, average speed of serve, distance covered by players, the trajectory of the ball, or even its rotation speed.

Data about rallies

Data provides information about the playing time. That specific data helps players to determine a play of action when it comes to the playing surface.

Data about impact area

Other statistics can refine the analysis, including an analysis of impact area of the ball. This data provides a global vision of the game. Players can study the impact of their shots in their last match. It can help a player to prepare a future match, for example. Moreover, this data gives information to the player on the best way to manage a key point. In order to prepare their player, a coach must also analyze the impact area of the future opponent.
On the tour, a system of video arbitration, called “Hawk-Eye” has been set up. First, “Hawk-Eye” can show to player the exact impact area of the ball. Secondly, this system registers all the impact area of balls during the match. After, the match, those data will give statistics.

Below, we can see the impact area of Andy Roddick’s serve. In the red, his aces; in yellow, his first serve and in black his second serve.
