2. Let the elbow swing as close to the body as possible, don't lift it, and avoid forearm exertion.
3. If you don't play in the east, the racquet should not be shoulder high.
Generally speaking, the angle between the arm and the forearm is about 150, the hitting point is in front of the body, and the waist height is the most comfortable hitting point. But different athletes will also adjust their most comfortable hitting points according to their technical movements.
Training methods of insufficient strength in tennis;
Feel unstable when hitting the ball.
There are three possibilities for this problem.
The strike point is not allowed. When hitting the ball, the hitting point is not accurate enough, and the ball is not hit with the sweet area of the racket, which leads to excessive vibration of the racket and unstable grip.
The strength of wrist and hand is not enough, which leads to unstable grip. This is purely a matter of strength. At the moment of hitting the ball, you need enough strength to hold the racket tightly and form a stable lever to return the ball forcefully. If the strength of the wrist and hand is not enough, it will lead to the deformation of the action at the moment of hitting the ball and cannot resist the impact of the ball.
The racket is too light. Generally speaking, the greater the quality of the racket, the easier it is to return the ball. The lighter the weight of the racket, the more it needs the grip strength and main power of the body to offset the work done by the ball to the racket. This is why professional players' rackets are generally heavier. The racket weight of professional players is generally at the level of 340g+.
Solution:
1. The hitting point is inaccurate and can only be improved through a lot of multi-ball practice. You can also improve your ability to stare at the ball through some games, such as hitting the ball with a racket frame.
If you can't play more balls, practicing the wall is also a good way. If you can beat the wall 100 times in a row, the movement will not deform basically, and you will basically achieve something.
At the same time, we should pay attention to whether the hitting action is reasonable. Unreasonable hitting action and poor footwork often lead to inaccurate hitting point.
2. The improvement of wrist strength and grip strength requires some small strength exercises, such as grip strength device and elastic belt. Through some strength exercises, we can improve the strength of small wrist muscles and prevent the injury caused by excessive use of the wrist.
3. It is generally suggested that even female players should use a racket of about 290g~300g if they are not helpless, and 320 g ~: p if they are fierce women. But the hitting action must be correct and reasonable to ensure that your wrist will not be injured.
Personally, it is not recommended for male players to use rackets under 295g.
In addition, if the racket is hard to thread and the number of pounds is high, it may also lead to excessive impact on the hand at the moment of hitting the ball, making it difficult for novices to hold the racket tightly.
2. The ball is slow and the hitting point is not deep.
1. The hitting action is not accurate and complete, the power chain is out of line, the strength is not enough, and the racket head speed is too slow, resulting in a slow ball speed and a shallow landing point.
The hitting action is incorrect, unsmooth and incomplete.
The development trend of modern tennis technology is to make full use of the body's power chain, taking forehand as an example, starting from the racket, in the open/semi-open position, squat, kick, hip rotation, waist rotation, shoulder rotation, forearm pronation, wrist acceleration and other actions are successfully completed in turn, and the body's center of gravity shifts from back to front, forming a very high racket head speed and exerting force forward, thus giving the ball great strength and rotation.
This kind of striking action can give full play to the energy of the human body's power chain, thus bursting out with the greatest strength. If the movements on any power chain are out of line, the power can't be transmitted in order, thus weakening the racket head speed and further reducing the hitting power.
If we carefully study the forehand skills of top players such as Federer and Dede, we will find that they all make full use of the power of kicking and turning, and their shoulders rotate greatly, even reaching 180. They aim at the ball with their left shoulder (right hand grip) when they lead the racket, and aim at the direction of the ball with their right shoulder after hitting the ball.
Generally speaking, their hitting action is like a spring compressed by tight rotation, which releases huge linear momentum and angular momentum after letting go, thus forming a very high racket head speed.
The higher the speed of the racket head, the greater the force on the ball and the faster the ball speed.
At the same time, sufficient shoulder rotation and shoulder delivery can make the ball fall deeper. Strong high-arc topspin can also ensure that the ball with deep impact can be hit with all its strength.
If the hitting speed is slow, you can record your hitting action, and then compare it with the hitting action of the top players, paying more attention to the details, so that you can know where the action destroys the power transmission of the power chain.
The action is not in place, resulting in incomplete hitting action.
If you watch the top players' games carefully, you will find that they are all trying to mobilize their opponents, let them hit the ball while moving, and let themselves stand in a more comfortable position to hit the ball.
From this point, we can see how important good anticipation and action are for hitting the ball.
Generally, it can be put in place in advance, and the shots prepared in advance can be fully utilized, with a high success rate.
On the contrary, if you always hit the ball on the move, you need your own absolute strength to maintain the speed and quality of the ball, and the error rate will also increase.
Therefore, we should improve our mobility, get in place early and prepare early, so as to give full play to our strength and ensure our placement.
The hitting point is not accurate, and the front is not enough.
Generally speaking, most professional players hit the ball on the front side of their bodies, the rising period or high point of hitting before the meeting. Such a hitting point can ensure that the player turns around completely and passes through the hitting area with the highest racket head speed, thus giving the ball the greatest strength.
If the hitting point is too close to the side, back or too far away from the body, the hitting force will not act on the ball effectively.
