MELBOURNE, Australia - Rafael Nadals new high-tech tennis racket looks and feels like his old one. Except for the on-off switch.Call it a smart racket, the latest advance in tennis technology tells you where you hit the ball — with the help of an app.Sensors embedded in the handle of the racket, made by Babolat, record technical data on every ball struck. At the end of a match or training session the data can be downloaded to a smart phone or computer and used to help analyze a players strengths and mistakes.Aside from the sensors, the racket is just a racket. Its the same size and weight as Nadals old-fashioned former racket.I know to play well I need to play 70 per cent of forehands, 30 per cent of backhands, Nadal said after racing through his first-round Australian Open match over Mikhail Youzhny, 6-3, 6-2, 6-2 on Monday. If Im not doing that, I know Im not doing the right thing on court.This (racket) is a way you can check these kinds of things, added the 14-time Grand Slam winner, who was sidelined for much of last season from a wrist injury and an appendix operation.The International Tennis Federation had previously outlawed what it calls player analysis technology during competition but adopted a new rule last January that allows players to wear or use smart equipment, like Nadals new racket and devices like heart-rate monitors that record data about player performance in real time.Babolat initially fitted the technology into its Pure Drive rackets, which are used by Karolina Pliskova , Julia Goerges and Yanina Wickmayer and then incorporated the sensors into a newly-released version of the AeroPro Drive racket used by Nadal, Caroline Wozniacki and Jo-Wilfried Tsonga.Dont expect to see players on their iPhones analyzing their game mid-match. An ITF ban on coaching during matches prevents players from consulting the data on court.The way it works is simple, says company spokesman Thomas Otton.There are two buttons on the bottom of the rackets handle.You press the on button. A blue LED light appears. And, you play, Otton said. When finished, a second button is pressed, activating Bluetooth which synchs the information with a smart phone or other device.Otton called up Nadals data from his practice session on Friday that lasted 1 hour, 31 minutes. In that time, he hit 572 shots, or 22 per minute, which broke down to 156 backhands, 222 forehands, 118 serves and 76 smashes.The data also gets more detailed and analyzes, for example, how Nadal hit his forehands — 133 had topspin, 49 had slice and 40 were flat.Swipe to the next screen and an image of a tennis racket appears that shows where the ball is making impact. For Nadals practice, he hit 42 per cent of shots in the centre and 20 per cent on top of the racket — the rest on the bottom and sides.At a demonstration of the racket before the tournament started, Wozniacki and Nadal joked about the pros and cons of knowing too much.Sometimes its not a good thing, said Wozniacki. Because you think youre hitting it in the middle of the racket, but really it shows you youre not. And theres no going around that.Nadals uncle and coach, Toni, joked that the racket would give him an edge.Sometimes when I correct Rafa on how hes hitting the ball, he doesnt agree. said Toni. Now I have the data.Nadal retorted, without missing a beat, Now he has the data to know that he was wrong. China Jerseys Wholesale .
