Andy Murray Tennis Serve
Last week, Rafael Nadal won the 2009 BNP Paribas Tennis Tournament in Indian Wells, California, beating Andy Murray in the final easily.
As we saw the tournament, we heard frequent arguments of Murray's second serve, and that if he could develop a better service to second would be almost unstoppable. Of course, he was almost unstoppable in Indian Wells but lost badly in the end, mostly due to poor serving. In that last game against Nadal, Games lost his serve four times and won only 6 of 16 (38%) of his second service points. Let's take nothing away from Nadal, however, he has the best game back on the court, possibly the best ever.
All tennis players, including beginners, know the importance of the serve. A good service can result in points easy and puts pressure on an opponent. The first and second serves in tennis usually have different objectives. With his first serve, you want to win the point with a as the winner of service, or at least put your opponent in a defensive position for the next shot. The first is to provide generally flat and fast and can run more risks, knowing they have an attempt at a second service if needed. The second service is the security of backup. His priority is to get the second service and start the point. If you miss the second service, you double-fault and give your opponent a free point. Most tennis players put a lot more spin on the second serve, but this tends to reduce the speed of the serve.
Due to the slower pace, the second serve often gives the receiver plenty of time to get in position to hit performance aggressive. However, if you can make your second serve a similar appearance to their first service, at least in terms of the service motion, you can make it difficult for the receiver to predict the speed (and type of motion) of the serve, and you may retain a significant advantage, even as they serve more slowly and with greater control.
We found some videos of Andy Murray first service and decided to look at it from a standpoint of biomechanics. This video is very good for analysis video. The camera is set up along the baseline, allowing us to get a side view of Andy during their service. We can also see the movement full-service video, including the head of the racket, and can see the racket making contact with the ball. It would have been great if we could've been throwing the ball complete (the ball leaves the top of the screen) and if the camera was stable and mounted on a tripod, but overall this is a good video footage sports analysis.

The power in the tennis serve, like many sports throw or hit (hitting and pitching baseball, soccer, shooting, and golf) is created by a chain events. Each share of the burdens of the body with energy and transfers its energy to the next link in the chain. The timing of this transfer of energy is essential to create racket head speed and therefore a good, fast service.
In Andy serve, we see starts with the bend of the knee while throwing the ball up. You may also notice that as you bend your knees, hips turn off the field. It then transfers this energy now stored in the hips to bring your back foot to front foot and rotating your hips in the yard. Again, notice that while swinging your hips back in court, his shoulders now turn away. This rotation against in both hips and shoulders creates the potential for racket head speed, Andy is coiled and ready to operate his racket to the ball.
As he does this, the potential energy is released, rotate your shoulders back in court, and throw his racket to the ball. All of these energy transfers joined to create the speed with which he hit at your service. If time is off, your speed is not as high.
Pitching is, of course, equally important. If you do not throw the ball consistently, it will be difficult to improve time coverage of his kinetic chain (described above). Andy ball launch is high and you fall on one foot inside the court. If you want to hit a good hard kick, the ball should be in front of you, so your body and the racquet moves forward when the ball is beaten. If pitching is directly overhead, it is much harder to move as theball much slower.
Ok, so Andy has a great first service, and we can see that here. It is his second serve that commentators were discussing. Unfortunately, we could not find any While images of his second serve to compare it with its first service. We are confident that your coach is working hard to improve their sequence and timing-chain to make it more difficult for opponents to read his second serve.
