Tennis technique is a sport about exerting strength and controlling strength, so what is the first key or most important factor of exerting strength in tennis? All the strength of the human body depends on the contraction or extension of muscles. If you want to exert your strength smoothly, you need your muscles to be in a very elastic state, just like an elastic rubber band. If you want to keep your muscles very elastic, you need to stay relaxed, not nervous. Tight muscles are like aging rubber bands, almost inelastic, and their ability to do work decreases a lot. The first key of tennis strength principle is to relax, and then relax. In addition, tennis is a sport that pays attention to the fine control of the racket face. In order to achieve this fine control, it is necessary to keep the arm muscles relaxed, because only by relaxing the arm muscles can we control the racket more keenly. For example, when writing, your fingers hold the pen too tightly, and you will feel that writing is not smooth, because this tight muscle will reduce the sensitivity of nerve conduction, thus reducing the fine control of the brain on your fingers.

So is the swing. In the face of the opponent's fastball, we subconsciously want to force the opponent's ball back, but in fact, for this fastball, it already contains enough energy. Just run to the scene, make dessert, swing easily, and you can easily hit the ball back without much effort. So in the face of the opponent's fastball, in fact, we don't need to use too much power to speed up the ball, just swing to change the direction of the opponent's ball. In the face of slow ball, you need to relax if you want to exert your strength. The more you want to exert yourself, the more you need to relax, so that the whole racket can be thrown out like a whip. If the arm muscles are tight, how to swing like a whip to improve the hitting quality? When taking the lead, the elbow should be high, and there should be enough space between the arm, the racket and the body. How to maximize the forehand strength of tennis? Avoid the "Tyrannosaurus Arm" and hit the ball in the effective area.

Second, the full spin makes room for the full swing of the arm driven by the full spin, which makes more acceleration for the swing. The muscle rotation force accumulated by rotation is also an important source of hitting power. However, it should be noted that the shoulder and hip are separated, and the shoulder rotation is greater than the hip rotation, rather than the whole body rotation. 2, fully stretch, fully swing the ball, the arm should be fully extended forward, and then continue to swing left and right until you catch the other side. Why did you hit the ball with your arm outstretched? Two reasons: one is to expand the acceleration space, which is the same as the first point, but the difference is that fully stretching the arm to hit the ball is mainly to expand the acceleration space after hitting the ball. The other involves the direction of the force. The purpose of fully stretching the arm to hit the ball is to exert greater forward force and make the ball have forward momentum and penetration.

Never shrink your arm and swing it from side to side as soon as you play, which will lead to a shallow hitting point. 3. Stay relaxed and make your strength smoother. If the body muscles are too tight, it will affect the contraction of the muscles, and if the grip is too tight, it will limit the transmission of strength to the racket head. Therefore, when hitting the ball, you should keep your body relaxed and relax your grip, so that the accumulated strength of your body can be transferred to the racket head smoothly and you can generate great hitting power. Especially after hitting the ball, you don't need to lock your wrist, relax your arm and relax your racket. After the swing is completed, you can try to loosen the grip and give the racket to someone who doesn't hold it.
