the stringing pattern can affect the playability of my racquet ?
The tennis enthusiast who approaches the world of the strings and everything that goes around should know , whatever his level of play , that the choice of the strings mounted on the racket are a crucial , fundamental and absolutely essential element for allow anyone to have fun on the playground and make the best without getting hurt .
We know that low tensions , now even widely used by high and pro level players , allow , above all with the actual polyester strings , to hit the ball with ease , to spin the ball vigorously without losing control and at the same time to limit impact shock and with it the possibility of contracting wrist , elbow and shoulder injuries .
What tension do you therefore recommend to maximize performance and limit the risk of injury ?
The answer is simple and lapidary .... WE SHOULD USE WITH ANY KIND OF STRING-SET , THE LOWEST POSSIBLE TENSION THAT ALLOWS US TO PUSH AND CONTROL THE BALL WITH EASE , HAVING ALWAYS CLEAR THAT OFTEN THE LOSS OF CONTROL IS LIABILITY OF CERTAIN TECHNICAL SKILLS RATHER THAN TECHNICAL INACCURACIES OF RACQUET AND STRING CHOICE .
But what solutions can we take if we want something more in terms of power , control , rotation , feeling , tolerance on decentralized shots and dynamic tension stability from a string that we like , that we already use and with which we find ourselves perfectly at ease ?
Can we modify the yield of our tool or affect the rigidity perception of the stringbed using a string pattern rather than another ? And what effects do they actually have in terms of stiffness and enlargement of the sweetspot , understood as a useful area of ball impact ?
A necessary premise concerns the fact that there is NOT a standard for the definition of the sweetspot and that in our case we have established as a " personal " rule that the variation of the measured stiffness deflection biases was less than 10 %.
We will review various types of 4 knot solutions , evaluating the pros and cons of each single solution in terms of tension applied on the vertical strings and on the horizontal strings , giving useful hints to those looking for the best for their tennis , knowing however that the data must be taken as a reference to the racket used and there are no general rules that make a better pattern in absolute terms than another .
From the experiment conducted directly using a new PURE DRIVE strung at 24kg with various pattern solutions , using a polyester monofilament from SIGNUM PRO - poly plasma 1.23mm , we have obtained some rather interesting data that will allow us then a comparison from scheme to scheme .
The tests conducted were performed following this protocol : - evaluation of the average equivalent tension of the racket just struck - vibration frequency of the newly strung racquet string-plane - evaluation of the loss of tension after 4-6 hours at rest - frequency of vibration of the string-plane after 4-6 hours at rest - evaluation of the static deflection of the string-plane at various points - estimate of the racket sweetspot and the uniformity of the tensions using the deflectional stiffness
