Tension in a string application

Answer 1

The more tension, the more control, but less power. The less tension, the more power, but less control. Tension is measured in pounds. On your racquet it should say how many pounds are recommended. Based on your preference you may want to add or subtract pounds (usually between 1 and 5 lbs) to your string tension. Also take note that different strings have different effects and feels on your racquet.
