Usage of playing tennis with thread:
Under the guidance of the coach, choose tennis with rope to practice after the tennis action is fixed.
Tennis with rope has two purposes:
1. Tie the end of the line without the ball to a fixture, and then hit the tennis ball in situ.
2. Tie the ball to the throat of the racket, or start practicing tennis like the first method.
Tennis court line with belt line
1. The boundary between the two ends of the court is called the bottom line, and the boundary between the two sides is called the sideline.
2. Draw a line parallel to the net at a distance of 2 1 ft (6.4m) from both sides of the net, which is the service line.
3. The court formed by the net and the service lines and sideline lines on each side is divided into two equal areas by the service center line, which is a line connecting the midpoint of the two service lines and parallel to the sideline line, and the width of the line must be 2 inches (5 cm).
4. Each baseline is divided into two equal parts by an imaginary extension line of the service center line with a length of 4 inches (10 cm) and a width of 2 inches (5 cm), separated by a short line, which is the "midpoint", and it is connected with the baseline at right angles and drawn from the baseline to the court.
5. Except that the maximum width of the bottom line cannot exceed 4 inches (1 0cm), the width of all other lines should be between1inch (2cm) and 2 inches (5cm). All measurements should be based on the outer edge of the line.
