Top serve?

Zhang Guan soon discovered that he did not have any extraordinary talents in track and field, and tennis. Thanks to the two skills of "body coordination" and "body flexibility" he was able to learn, otherwise Zhang Guan's tennis learning skill would be terrible.

Sharapova handed a towel to Zhang Guan and said at the same time, "My dear, it seems that you don't have the talent to play tennis, otherwise you should help me control the tee!"

"Control the serving machine?" Zhang Guan sighed helplessly, and his serve is indeed not as good as the serving machine.

"Maria, I just didn't take it seriously! Do you want me to serve again?" Zhang Guan looked at Sharapova with anticipation.

Sharapova sighed helplessly, "Well, then try it with you again!"

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

"Either way, I have to learn to serve! Otherwise, Maria will always devalue ​​me, and I won't even have the qualification to practice with her in the future!" Zhang Guan thought of this and found tennis-related skills in the system.

There are many skills related to tennis, and the skills related to the hand involve serving, receiving, topspin, downspin, high pressure, volleyball, etc., and the rapid movement of the foot in all directions and the control of the broken step are also all had their relevant skills.

Zhang Guan currently has a lot of skill points. Last year he participated in the IAAF Golden League, Grand Prix, and Super Grand Prix together for a total of more than a dozen games, which earned him more than 30 skill points. There are also twelve skill points for breaking the world record. Also, although the rewards in the indoor competition in the first half of the year have decayed, plus the two world records of 60 meters indoors, there are more than a dozen skill points credited. Therefore, the skill points accumulated by Zhang Guan at this time can be used to purchase a lot.

"Let's learn how to strengthen the tennis serve. When you reach the master level, that's three skill points. It's time to beat the beauty." Zhang Guan thought of this and learned the skill of "tennis serves to strengthen" to the master level.

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

What is the quality of the service? The tossing plays a key role. The height of the tossing cannot be too high or too low. The position should be proper. At the same time, the shot should be as smooth as possible. The simpler the tossing action, the better, such as hooking your finger, throwing your wrist, etc., are small extra actions for tossing the ball, which may affect the stability of the ball after being thrown. Also, the less the ball spins under control the better it is, if it is straight up and down without rotating at all, it is the most conducive to serving.

At the same time, tossing the ball also requires the best time for the ball to disengage. The best point for the ball to disengage is the highest point of the palm rise. If the ball is dismissed too early, it will easily cause the ball to spin or shake in the air, affecting the stability of the ball; If the sale is too late, the ball will move in the direction of the athlete's head, and it is not easy to serve the ball later.

And the position of the toss also affects the serve. Generally, if the position of the toss is higher, the power after the service will be greater and the speed will be faster, but the hitting point will also be forward, and it is not easy to grasp the landing position. It's easy to serve out of bounds, so if you want to use a more aggressive serve, put the tossed position forward.

Conversely, if the tossing position is late, the success rate of serving will be higher, and it is easier to control the rotation of the ball and the landing point of the ball. It is also easier for the opponent to receive the ball after returning the ball, so if you choose to be more stable and conservative serving tactics, you can throw the ball position later.

For beginners, it is important to understand that "tossing" and "throwing" are two different concepts. To serve a tennis ball, you need to toss, not throw. This time Zhang Guan practiced many times before he slowly found the feeling.

Sharapova still has a charming smile. Tennis is a talented sport. She has already confirmed that Zhang Guan has no talent in tennis, so she is playing with Zhang Guan.

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

Next, Zhang Guan started swinging and hitting the ball.

While tossing the ball, the hand holding the racket will begin to swing back. When the racket is swung to a certain angle, the elbow will be used as the axis, and the forearm, hand, and racket will hang down to the back. At the same time, because the knee is bent at this time, it looks like a "bow". The angle of this kind of backswing is not clearly defined, most of them are different from person to person, and height, hand length, gripping habits, etc. all have an influence.

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

The hitting of tennis is not just the strength of the arm, but the power of the whole body, driving the racket in the hand to the hitting point and successfully hitting the ball. The last point of power is the moment it hits. This is a whole movement. If you take the right-handed player as an example, the body rotates counterclockwise laterally while the upper arm rotates upward, kicking, heartfelt, turning, swinging, etc. The perfect combination can make a successful serve. In the process of serving, you often see athletes' feet leaving the ground. This is not an active jump, but the force caused the feet to passively leave the ground.

There are many other techniques for professional tennis players to serve, such as the most commonly used counter-rotating serve, the relatively stable top-spin serve, and the most difficult American-style spinning serve. The current Zhang Guan does not understand these techniques, the only thing he knows is the leveling serve used by beginners.

Although flat serve is a beginner serve, it is the fastest serving method of all servings. This kind of serving method requires fast speed, low rebound, and great power. For tall and sufficient athletes, they can be regarded as a big killer, but unfortunately, the hit rate is relatively low.

International top tennis players also like to use a flat shot in the first serve to fight the ACE ball or serve to score after the first server fails, they will choose to add rotation to the second serve.

"This move looks very good! More progress than before. The hitting point is relatively accurate and the movement is very smooth! This service is considered a qualified serve!" Sharapova continued to comment.

Then, Sharapova was ready to catch the ball.

"Whoosh!" The tennis ball turned into yellow light and flew over Sharapova, and at this time Sharapova was just about to start making movements, and the racket didn't even reach out.

"This serving is so fast! The serving speed was over 120 miles per hour!" Sharapova looked behind in surprise, the ball hit the fence wire, and then fell off, rolling on to the ground.

Of the world-class male professional tennis players, if they use a flat shot to serve, the normal serve speed is probably at 120 miles per hour, while athletes such as Federer and Nadal serve more than 125 miles per serve. Normally, the second shot will generally be more than 10 miles slower than the first shot. But Zhang Guan is just a beginner. This kind of beginner's serve speed is far inferior to women athletes. Sharapova has never seen any beginner be able to deliver a ball at a speed of 120 miles per hour.

As a female athlete, the normal first-serve speed is about 105 miles per hour, and the second server may even drop to about 90 miles per hour. Among the female athletes, such as the most fierce server, Williams, the highest service record is 125 miles per hour. So for a female athlete, it is difficult to catch a serve that exceeds 120 mph.

"It's a coincidence! It must be a coincidence! Just now the serving is so bad, how can he serve such a quick ball all at once!" Annoyed and dissatisfied, she shouted at Zhang Guan, "Come again!"

This time, Sharapova was not distracted by Zhang Guan's serve but focused on catching the ball.

Tossing, bowing, and hitting the ball, Zhang Guan once again served.

"Shoot!" Another yellow flash flew by.

"Come on! It's still so fast!" Sharapova was shocked, but this time she focused a lot, and Zhang Guan's serve was originally the simplest flat serve, so Sharapova responded. She moved quickly, and then reluctantly made a return movement.

"It's over! The ball was so bad, it was either intercepted in front of the net, or you would get a reverse angle!" Sharapova made a precise judgment as soon as she returned the ball.

Then Zhang Guan ran over, returned a ball, and steadily drew the ball onto the net.

The ball should not go to the net!

"Hahahaha ..." Sharapova suddenly smiled happily, and she remembered that Zhang Guan was a rookie. Although the two servings were very good, the return was still a rookie. Sharapova just proved that bad service can only be said to be within the bounds. If the angle is not a right angle, the speed is just fast, even the lowest level professional athletes can easily complete it, but Zhang Guan obviously can't do it.

Zhang Guan also felt very embarrassed. He also knew that he had missed a good chance to receive the ball like a pro.

"Keep laughing, if it's a game, it would be only 15-15 now, and it's still my serve. Next, I have to be serious." Zhang Guan stood in position and was ready to serve again.

"Master tennis receives the ball." At the same time, Zhang Guan spent three skill points and learned one skill.

"Wait!" Sharapova suddenly stopped Zhang Guan and then asked, "You just served two times, both are almost the level of professional men's athletes. How did you do it?"

"Talent!" Zhang Guan smiled awesomely, then said, "I am a genius! Be prepared, I want to serve this myself!"

Zhang Guan's third serve, just like the previous two, the serve speed still exceeds 120 miles per hour.

Sharapova responded immediately, and this time she was still in a hurry to receive, but both the angle and the landing were much better than before.

However, Zhang Guan's performance has also improved a lot...
