Wholesale OEM Training Tennis Ball

Tennis service should be sent in the following way. The service player shall stand before starting to serve, that is, stand behind the baseline (that is, the side away from the net), within the assumed extension line of the center mark and the sideline. Then the service player should throw the ball in any direction in the air with his hand and hit the ball with his racket before it touches the ground. At the moment when the racket contacts the ball, the whole transmission is considered to have ended. A player who can only use one arm can use his racket for throwing.

The rackets are made of wooden rackets, aluminum alloy rackets, steel rackets and composite (nylon, carbon) rackets. Any racket can be used in the game. The hitting surface of the racket must be flat, interwoven or connected from the string line to the bottom, and its composition format is completely consistent. Each string line must be connected with the racket frame. The total length of the racket frame and the racket handle shall not exceed 73.66 cm, and the total width of the racket frame shall not exceed 31.75 cm.
