Zhang Guan soon discovered that he had no outstanding talent in athletics, and he still did the same in tennis. Thanks to the two skills of "body coordination" and "body flexibility", otherwise Zhang Guan's tennis learning would be really miserable.

Sharapova handed a towel to Zhang Guan and said, "Honey, with all due respect, it seems that you really don't have the talent to play tennis, or you should help me control the ball machine!" ”

"Controlling the ball machine?" Zhang Guan sighed helplessly, his current serve is indeed not as good as the ball machine.

"Martha, I'm just not serious! Do you want to try to let me serve again? Zhang Guan looked at Sharapova expectantly.

Sharapova sighed helplessly: "Okay, then let's try it with you again!" ”

Zhang Guan stood on the sideline again, picked up the racket, and prepared to serve.

"I've got to learn how to serve! Otherwise, she will always be degraded by Martha, and she will not even be qualified to practice with her in the future! Zhang Guan thought of this and found tennis-related skills in the system.

There are many tennis-related skills, and the skills related to the hand involve serving, receiving, topspin, downspin, high-pressure, volleying, etc., and the fast movement and broken step control in all directions on the foot are also related skills.

Zhang Guan still has a lot of skill points, last year he participated in the IAAF Golden League, Grand Prix, Super Grand Prix added up to more than a dozen, which earned more than 30 skill points, and three times to break the world record also has 12 skill points, in addition to the first half of the indoor competition in the reward although the attenuation, but plus two indoor 60-meter world records, there are more than a dozen skill points in the account. Therefore, at this time, Zhang Guan has accumulated skill points, and he can learn a lot of skills.

"Learn this tennis serve to strengthen, to the master level is three skill points, just smile as a beauty." Thinking of this, Zhang Guan learned the skill of "tennis serve strengthening" to the master level.

Subsequently. Zhang Guan took a deep breath, stabilized his movements, and threw the tennis ball into the air.

How is the quality of the serve, the ball plays a very key role, the height of the ball should not be too high, nor too low, the position should be appropriate, and the shot should be as smooth as possible when throwing the ball. The crisper the ball throw, the better, such as hooking the fingers, throwing the wrist, etc. are redundant small actions for throwing the ball, which may affect the stability of the ball after throwing. In addition, the less spin the ball can control, the better, and if it is completely non-spinning, it is best to serve.

At the same time, throwing the ball also has requirements for the best time for the ball to get out of the hand, the best point for the ball to get out of the hand is the highest point of the palm to rise, if the ball is out of the hand too early, it is easy to cause the ball to rotate or shake in the air, affecting the stability of the ball; If the ball is sold too late, it will move towards the back of the player's head, making it difficult to follow the serve.

In addition, the position of the ball is also affected by the serve, and if the position of the ball is thrown forward, the force of the ball will be greater and the speed will be faster. However, the hitting point will also be forward, and it is not easy to grasp the landing point, and it is easy to serve out of bounds, so if you want to use a more aggressive serve. Just throw the ball a little forward.

On the other hand, if the ball is thrown backwards, the success rate of the serve will be higher, and it is easier to control the rotation of the ball and control the landing point of the ball. It is also easier for the opponent to return the ball, so if you choose a more stable and conservative service strategy, you can throw the ball a little further back.

For starters. It is important to understand that "throwing the ball" and "throwing the ball" are two different concepts, and the serve of tennis needs to throw the ball, not the ball. Zhang Guan also practiced this many times before he slowly found his feeling.

Sharapova on the other side still maintained a charming smile, tennis is a very talented sport, she has already confirmed that Zhang Guan has no talent in tennis, so she should accompany Zhang Guan to play games.

"The feeling of throwing the ball this time is good, the height is good, much stronger than the previous times!" Sharapova commented silently in her heart.

Next, Zhang Guan began to swing the racket to hit the ball.

When the racket swings back to a certain angle, it will take the elbow as the axis, and the forearm, hand, and racket will hang down to the back, and at the same time, because the knee is bent at this time, the body looks like a "bow". There is no clear rule on the angle of this back swing, most of it varies from person to person, and height, hand length, grip habits, and so on have an impact.

The ball was thrown into the air, Zhang Guan's body also made a "bow" shape, and the next moment, he began to hit the ball.

The shot of tennis does not rely on the strength of the arm alone, but on the power of the whole body, driving the racket in the hand to swing to the hitting point, and the final power of the explosion point is just the moment of hitting. This is an overall action, if you take the right hand player as an example, the body is actually rotating horizontally and counterclockwise, while the upper arm is rotating upward, and a perfect combination of a series of forces such as kicking, heart, turning, and swinging can make a successful serve. In the process of serving, it is common to see the athlete's feet off the ground, which is not an active jump, but a passive departure of the feet from the ground caused by the force used in the serve.

There are many other techniques used by professional tennis players, such as the most commonly used counterspin serve, the more stable topspin serve, and the most difficult American spin serve. And the current Zhang Guan obviously doesn't know these techniques, the only thing he knows is the flat serve used by beginners.

Although the flat serve is known as a beginner serve, it is actually the fastest of all serves, this way of serving is fast, low rebound, powerful, for tall and powerful athletes, it can be regarded as a big killer, but unfortunately the hit rate is relatively low.

Many of the world's top tennis players also like to use a flat serve to spell an ace or serve to score points on the first serve, and only choose to add spin to the second serve after the first serve fails.

"This action looks pretty good! It's a lot better than before. The hitting point is relatively accurate, and the movements are smooth! This serve is a good serve! Sharapova continued to comment in her heart.

Then, Sharapova was ready to go and catch the ball.

"Whoosh!" The tennis ball turned into a yellow light and flew past Sharapova, who was just about to start making a move, and the racket didn't even have time to be extended.

"Such a fast serve! The speed of the tee just now is definitely over 120 miles per hour! Sharapova looked behind her in surprise, as the ball had just bounced off the barbed wire of the fence, then fell and was rolling on the ground.

Among the world's leading men's professional tennis players, if they use a flat serve, the normal speed of the first serve is about 120 miles per hour, while athletes of the level of Federer and Nadal are the norm to exceed the speed of 125 miles per hour on one serve, and more than 10 miles slower than the first serve on the second serve. But Zhang Guan is only a beginner, and the speed of such a beginner is far from that of a female athlete, and Sharapova has never seen a beginner who can send a ball at 120 miles per hour.

As a female athlete, the normal speed of the first serve is about 105 miles per hour, and the second serve may even drop to about 90 miles per hour. Among the female athletes, such as Serena Williams, who served the most ferociously, the highest serving record was 125 miles per hour. So it's hard for a female athlete to catch a serve that goes over 120 miles per hour.

"It's a coincidence! It must be a coincidence! I was so bad at serving just now, how could I send out such a fast ball all at once! Sharapova is a Grand Slam player after all, she didn't catch a rookie's serve, and she was a little annoyed and unconvinced, she shouted at Zhang Guan: "Come again!" ”

This time, Sharapova was not distracted from commenting on Zhang's serve, but focused on receiving.

Throwing the ball, bowing down, hitting the ball, Zhang Guan served again.

"Whoosh!" Another yellow shadow flew in.

"It's coming! Still so fast! Sharapova was shocked, but this time she was much more focused, and Zhang Guan's serve was originally the easiest flat serve, so Sharapova still reacted, she moved her feet quickly, and then reluctantly made a return action.

"It's over! This ball is so bad that it will either be volleyed in front of the net, or it will be hit at a reverse angle! Sharapova made a precise judgment the moment she returned the ball.

Then Zhang Guan ran over, returned the ball, and steadily pumped the ball into the net.

The return ball is not over the net!

"Hahahaha......" Sharapova suddenly laughed happily, she remembered that Zhang Guan is a rookie at all, although these two serves are very good, but the return is still a rookie, Sharapova's bad serve just now can only be said to be barely in bounds, to angle no angle to speed no speed, even the lowest level of professional athletes, can easily complete the score, but Zhang Guan obviously can't do this.

Zhang Guan also felt very embarrassed, and he also knew that he missed a good opportunity with a scum-like return.

"What are you laughing at, if it's a match, it's only 15-15 now, and it's still my serve, so I'm going to be serious about it." Zhang Guan stood in his position and prepared to serve again.

"Master Tennis Catch." At the same time, Zhang Guan spent three more skill points and learned a skill.

"Wait!" Sharapova abruptly stopped Zhang Guan, and then asked, "Your two serves are almost at the level of professional male athletes." How the hell do you do that? ”

"Talent!" Zhang Guan smiled very awesomely, and then said, "I'm a genius!" Get ready, I'm going to serve! ”

Zhang Guan's third serve, like the previous two times, still exceeded 120 miles per hour.

Sharapova reacted immediately, and this time her return was still a bit rushed, but both the angle and the landing point were much better than before.

However, Zhang's performance has also changed a lot better...... (To be continued.) )
