Don't underestimate serve from left, a more prominent serve from left with spin is just as dangerous!
As an easy-to-learn and fast serving method, serving from left still plays an important role among hobbyists.
Normal serving from left includes reverse rotation, side up and side down. If you can spot a left serve confusion, threat of a left serve is also very high.
The side and side backhand serve is a relatively common delivery technique. Today we will look at Ocharov's side-spin serve technique. It differs from side-up and side-down serve, which focuses on difference in spin.
Let's first take a look at technical animation of Orci side-spin serve. From animation, it can be seen that Orci's swing slides from left to right, and point of contact between racket and ball is mainly in center of ball. The right side is slightly lower, so that ball produced by friction has a higher proportion of lateral rotation, which is mainly lateral rotation or slightly weak reverse rotation.
After swing path is clear, let's take a look at angle of racquet. In moving image, we can see that face of Orchha racket is slightly tilted as racket moves, and face of racket is basically kept at same angle when it touches ball. At approximately 80°, surface of racket after touching ball is mostly perpendicular to ground, and verticality The surface of racket is also designed to reduce backspin or topspin of ball. .
The whole action of serving ball is to pull racket to right and back by rotating waist after ball has been tossed up. , The joints force whole arm to exert force to support, and direction of force is more towards friction ball from left to right, reducing upward or downward force.
Short balls tend to be served less often with side spin, while long balls are more dangerous. In order to better control arc, choice of point of impact should be as low as possible, and ball should try to hit at same height or just below net.
Ocharov's serve can take a place on international stage because his serve from left is very confused. The entire set of serving motions is very consistent, with only direction of force different when touching ball. See above two movements As shown in figure, difference between side spin and side spin is very subtle, and it is difficult to judge ball's spin from motion.
In a left-hand feed system, side-spin feed must still be used in combination with side-up and side-down feeds. Confusion in overall movement is key, and it's also an issue we need to pay attention to when practicing serve from left.
