String tension is one of the most important variables in tennis racket configuration. Different tensions have their benefits and drawbacks for both your body and game. String tension is easily manipulated. Whether you are looking for a little more power or control, your nearby racket stringer can help by adjusting string tension.
Common Tension Ranges
Most tennis rackets are strung with 50 to 65 lbs of tension. Each racket has a recommended tension range, usually written on the inside of the throat. While it is not crucial to follow this tension range, it is a good starting point for most players. Decreasing or increasing tension beyond this range should be done only by experienced players desiring a specific benefit from such an extreme tension.
High Tension Ranges
High tensions, those above 58 pounds, give a player more control and less power. This can be a benefit for advanced players and those who produce considerable amounts of power. High string tensions help to reign in excess power and make it controllable. High tensions also provide a crisp feel with plenty of feedback to the player. Although feel is a highly subjective attribute in tennis, many players enjoy this crisp, stiff feel from the string bed.
Low Tension Ranges
Low tensions, those below 55 pounds, offer more power to players but at the expense of control. Lower tensions cause the ball to leave the racket string bed at a higher launch angle, causing loopier shots. For players who need extra power or those with low powered rackets, lower string tensions can provide additional free power. Low tensions give a softer, more cushioned feel on racket impact.
High Tensions and Tennis Elbow
High tensions create a stiffer string bed, which can, in some cases, contribute to tennis elbow. The stiff string bed transfers more shock and vibration to the arm, leading to further irritation of already inflamed tendons. Any player suffering from tennis elbow or with a history of arm problems should strongly consider lowering their string tension.
