Stringing your tennis racket at a low tension will also impart more spin to the ball, which is great news if you love to hit a heavy ball! This happens because the ball can pocket deeply into the string bed; the increased elastic effect causing a greater snap back effect on the string bed and launching the ball back with a greater number of RPMs than a higher tension.
Players often say “high tension strings bite into the ball giving more spin.” (“Biting” is used in common tennis parlance to mean creating more friction by increasing the space between strings for the ball to sink into; using rougher, stickier, textured, or shaped strings to “grab” the ball; using thinner strings to dig into the ball; or using higher tension to increase surface contact forces.)
Now that we know that string tension doesn’t influence spin, we can also understand that it can’t affect control. Lateral String Movement: The research didn’t stop there. Using an ultra-high-speed video operating camera, they recorded the impact from behind the racket. The video camera operating was at 3,700 frames per second, and they were able to see and measure what happens to the ball and strings.
The higher your string tension, the more control you’ll have while the looser your string tension, the more power. Here are the above tension ranges again, but adjusted for power or control: Nylon/Gut: 50-60lbs (22.5-27kg) Power: 50-55lbs (22.5-25kg) Control: 56-60lbs (25.5-27kg)
Does the string type and tension make a difference to spin? Spin depends on many factors. It primarily depends on the incoming ball parameters, such as spin, speed, and angle of trajectory, as well as the swing parameters, such as the racquet speed, angle, and tilt.
The best string tension for most players is normally between 48 and 54 lbs. A looser (lower) tension offers more power, but stringing tighter enables better control. Beginners will probably want more control, so may prefer a tighter tension at first. Strings lose tension over time, and pros, who use a very wide range of tensions, get very frequent restrings to avoid this.
Furthermore, a lower tension for polyester strings may help improve the ability of a string to snap back and subsequently deliver more spin. For this reason, many players use lower-powered polys. Not only do they have topspin enhancing qualities, but more importantly, they allow the player to swing harder to increase spin.
This string can offer both a lot of power and spin-based quality elasticity. Without spin properties, the string may feel a little out of control once it loses tension. For those who look for strings that help out their elbow, wrist, and other joint pain problems, this is a great solution without breaking the bank.
