Frequently on television to see players use the reverse rotary method of serving their own very much like to find out, reverse the difference between spin and backspin, how then sent the ball against the spin?

Table Tennis axis of rotation axis from top to bottom, left axis, front and rear axle. Under the rotation axis as the center for more than the corresponding left and right spin, to rotate around axis as the center corresponds to the upper and lower spin, before the rear axle as the center corresponding to reverse rotation, Shun rotation. Simply put, a reverse rotation is a counterclockwise rotation before the rear axle as the center, cis-rotation is a clockwise rotation before the rear axle as the center. Reverse rotation and the next spin are the two basic spin, almost no single rotation, are mixed.

Reverse rotation refers to rotating the opposite with the usual right-handed forehand serve serve the general Wang Zuoce (bottom) friction ball, while the reverse rotation driving is Wangyou Ce (bottom) friction ball. Right-handed backhand serve the general Wang Youce (bottom) friction ball, while the reverse rotation driving is Wangzuo Ce (bottom) friction ball. Left-handed forehand serve the general Wang Youce (bottom) friction ball, while the reverse rotation driving is Wangzuo Ce (bottom) friction ball. Left-handed backhand serve the general Wang Zuoce (bottom) friction ball, while the reverse rotation driving is Wangyou Ce (bottom) friction ball.

For the catch: reverse rotation - that hit the ball when going against the original direction of rotation of friction, such as: the next spin the ball with rubbing backspin, topspin on the ball spin to spend pull Note: cis-spin - that hit the ball When the original ball spin along the direction of friction, such as: for the next spin the ball one way or another spin, right spin on the ball with backspin rotation to avoid cutting - refers to time to avoid hitting the ball rotation, lateral friction and ball rotation axis , such as: upper and lower spin to the ball with rubbing (write, pull) side of the spin
