What are the benefits of stiff racquet?

The stiffness of the racket is an advantage or a disadvantage for the players of Club?

Few meanings essentially “positive” that can be attributed to the rigidity. Also with regard to the tennis racquets, few times it is heard cite the rigidity of a frame as one of its best characteristics, indeed. On the scales terms like flexibility and softness have always been most successful. It’s time to do some clarity on the concept of rigidity of a frame trying to explain all the implications, even positive ones.

In principle, the data associated with the rigidity line measured by a Diagnostic Center, is an expression of the degree of bending of the frame to the impact with the ball . What happens then? Occurs a first deflection of the string (stringing) and secondly flexes the racket itself, which then returns “reflected” in the opposite direction to the original position by pushing (hopefully beyond the network) the ball.

POWER – So is important to emphasize that the frame flexes less, less energy disperses. A stiff racquet scatters less energy (less flexing of a flexible frame) at impact. The energy potential more (preserved because “not absorbed”) is expressed in terms of power: a greater rigidity corresponds (at the same weight, balance, mass, etc.) More power. A flexible racquet subtracts thus more energy to the ball. And in this regard it is disproved the cliché catapult effect: many players or fans think that a flexible tool can return more torque and power because of a sort of sling-effect. In fact the ball remains on the strings only 3-4 milliseconds, much less than the racquet employs to return to the initial position. Consequently, the frame of a racket does not “return” energy to the ball, but more simply it absorbs less or more depending on the rigidity. To be more precise a trivial example: throw a ball against a wall and then against a mattress (the first disk, the second smooth). The output speed of the ball will obviously be greater in the first case (and not just), because the mattress absorbs the energy of the incoming ball.

CONTROL – But is not only the power to be affected in some way by the rigidity of the racket, there are also at stake control and comfort. The high rigidity of a particular tool makes that the exit angle of the ball is affected less than that of a softer racquet. Translation? Better accuracy, contrary to what one usually says (power and control inversely proportional). For advanced level player excessive rigidity (and therefore higher power) cannot be used, because the skills and technical capabilities also allow you to hit with power and control with flexible tools. Instead of a club with a rigid frame intermediate player can obtain important advantages in terms both of control power.

COMFORT – The real sticking point of a racket with considerable stiffness values (say over 65) is comfort. This is because to parity of other characteristics, even if a more flexible tool transmits vibrations to the wrist, arm, elbow and / or shoulder the more rigid involves a greater impact shock. In a general sense a feeling of comfort is pretty subjective game that everybody perceives differently; difficult to quantify, at least objectively. However, those suffering from problems or discomfort in the arms or shoulders draws more help from the use of flexible tools; and come in a range of other decisive factors such as stringing and anti-shock mounted now “standard” on most racquets devices, especially those amateur (Kinetic, Cortex System, etc. etc.).

ROTATION – As mentioned, the ball impacted by a more rigid chassis leaves the stringed more quickly; this means that at constant other features, it is more difficult to be able to give adequate and effective spin (especially top exasperated “Spanish style”) that turn, are easier with flexible racquets.

CONCLUSIONS – It should be clear at this point that the stiffness of a racket, is not a “negative” factor, linked to the cliché of the “vibrations.” Indeed it can be concluded, dispelling another myth, that the amateur racquets are stiffer on average than competitive (or professionals). And thank goodness, because this way they can help the club players, increasing power and control.
