In the era of the 4.0 revolution, tennis, like many other sports, is not outside the law of change and development.
Go behind in the tennis
In Brent Salazar’s previous job as a fitness coach at the American football tournament (NFL), his player always wore GPS devices to track their training volume at each minicamp, training camp. practice and practice in the middle of the week. On competition days, their shoulder pads are equipped with Zebra’s RFID. No matter how fast or how fast each player moves, there is no question.
When Salazar became a professional director at the US Tennis Association (USTA), a position he took over two years ago, he was surprised to see access to the technology of new tennis at the stage. stub. According to Salazar, the sport needs a more sophisticated approach to European sports science in order to truly understand the demands of a match and the training that follows.
In 2018, USTA deployed Kinexon super broadband technology at its athletic development center in Orlando, thereby bringing the most used data tracking system in the professional basketball (NBA) into tennis. However, it was only this summer that the International Tennis Federation (ITF) accepted Catapult Sports’ OptimEye S5 as the first GPS device to be worn in competition. However, the men’s and women’s leagues have not yet received ITF confirmation, so only Grand Slam, Davis Cup and Fed Cup matches can use OptimEye S5. The Hawk-Eye optical tracking camera, meanwhile, can provide motion information from most tournaments, but not all racquets have access to raw data.
However, USTA is trying its best to grasp the physical requirements of this sport. Two months ago, IBM launched the Coach Adviser portal to help US tennis players and coaches quantify their efforts in Hawk-Eye data matches, which could help set up a training plan.
Change with the trend
A racquet in a single match must protect a 39-foot, 27-foot wide pitch. And think of rackets like Novak Djokovic and Roger Federer having to play 5 sets in the Wimbledon final in July, with a total of 422 points, how will their bodies work?
According to Craig O’Shannessy, an analyst at Djokovic and owner of Brain Game Tennis, he saw data showing that racquets can move an average of 8 to 12m/point. While no one seems to delve into this, some other analysts agree that 10m is a reasonable estimate for a professional racket.
Using that number as a benchmark, Djokovic and Federer each move about 2.6 miles in their match. However, this hardly tells the whole story with moments of acceleration, deceleration and change in direction. According to O’Shannessy, the distance of the racquet’s interesting rather than important is because there is no data to suggest that a player who runs at least in the match will win more or lose more.
Back to Salazar. He worked with Kinexon’s Paul Robbins, to apply wearable technology to tennis. Compared to basketball, the speed areas are very different. The racquets can spend most of their time moving slower than 3 miles per hour – walking speed – and almost never more than 16 mph.
