It depends on how hard the ball is hit, the position of the strings before impact, and also exactly where on the racquet you hit the ball — i.
The lesson is that a low-tension string will give you less consistency in your strokes. In sum, lower tensions result in more lateral string movement, which, in turn, contributes to more unpredictable ball trajectories. The player may also be able to feel this string movement since it will result in a softer impact. Different groundstroke speeds were simulated by varying the velocity at which the ball and racquet collided.
At these different ball-racquet collision speeds, we measured the distance that the ball travelled along the stringbed during impact using images such as those shown in Figure 1. We also measured the length of time dwell time that the ball was in contact with the strings during impact. Figure 2 a shows that the contact time for the balls impacting on the racquet strung at 70 pounds is 20 percent shorter than for the racquet strung at 40 pounds.
This is simply due to the pound stringbed being stiffer than the pound stringbed. Figure 2 b shows that the ball travels consistently further across the stringbed for impacts on the racquet strung at 40 pounds. This is because the ball remains in contact with the strings for a longer time on this racquet, and it therefore travels further across the stringbed. The racquet is moved forwards and whipped upwards.
The probability that the shot is executed correctly will be increased if the distance that the ball travels across the stringbed is minimized. This highlights that the contact distance will have a direct link to the players ability to play a topspin shot. So, tighter strings will increase the probability of a successful topspin shot. How does this correspond to what the player feels?
The contact time will also influence your perception of control in another way. For any shot in which the ball does not land perfectly on the long axis of the racquet, the head will rotate during impact.
The longer the ball remains in contact with the racquet, the greater this undesirable rotation will be, leading to large errors in your shot precision.
So, the longer the ball is on the strings, the farther it will travel on the stringbed, increasing both the racquet twisting in your hand and the chance for hitting the frame or less responsive parts of the stringbed. Higher tensions reduce all of these unwanted effects. Changing racquet tension does not affect spin, but it does affect string movement, dwell time, and ball contact distance. The main advice is that high string tensions make your shot more consistent and make it easier to hit topspin shots.
From the January issue Permalink. Tennis Industry magazine. Are you a beginner, intermediate, or advanced player? Skill level will often impact string preferences. The key, of course, is to be honest in your self-assessment. Here is the chart one last time, but with recommended tension ranges narrowed down by ability:.
Three new polyester strings that are easier on the arm: 1. But this premium monofilament delivers more comfort than a typical firm poly, with dependable control. It offers friendly feel, as well as a little extra punch.
The softening agent in this more flexible version provides a slightly plusher option for a wider range of users. We advise to decrease the tension by 1kg. In indoor, we will add this kg of tension. Also know that the types of strings react differently to changes of weather and temperature.
Gut, for example, suffers little from the bad weather, just like multifilament, while polyesters suffer more from cold temperatures. Many players in professional tournaments explicitly demand that their racquets be strung the very morning of their match, so that they do not have time to lose tension during the night.
The "static effect" has to be taken into account and in other words, when you reopen your tennis bag to hit the ball after a long break, your strings are naturally loosened. It is then necessary to tighten it again in order to get your good sensations back, and to avoid tiring your arm. Many tennis players think that a string only has a small impact on the game. A little more comfort in multifilament, versus better durability in polyester, and that's it.
Well, no. Choosing the right tennis string is not trivial. A bad choice and we can end up playing with a string that does not suit us, that does not match the characteristics of our game.
