In tennis, a race of blow of axe is a projectile where the angle towards the player and behind the racquet, made by the line of the flight of the ball, and the racquet travelling downwards through it, is of the 45 degrees larger than and can be 90 degrees. The face of racquet passes slightly apart from the ball and swallows the side, cutting it, because a man cuts wood. Rotation and the curve are of right-hand side on the left. He is made with a stiff wrist.
The drawn section simply reduced the angle mentioned of 45 degrees downwards with very small. The face of racquet passes inside or apart from the ball, according to the wished direction, whereas the race is mainly a torsion of wrist or snap. This snap gives a cut of ensabotage decided to the ball, whereas the drags of a blow of axe swell in addition to ground without cut.
The rules of the work of legs for these two projectiles should be identical that the order, but because both are made with a short oscillation and more play of wrist, without need for weight, the rules of the work of legs can more without thrown being risk and position of body also carefully not considered.
These two projectiles are primarily defensive, and are the devices to reduce work when your adversary is on the base line. A blow of axe or a section is very difficult to lead, and will break to the top any play of control.
