They come from a place of perfect logic and rational. However, one of the areas many players get themselves into trouble is by using a stiffer racquet with a harsh string like polyester. But in doing so, the racquet builds up momentum and overshoots its starting position. There are other machines around from Prince and Gamma, but Babolat is the most widely used and trusted machine out there.

Hi guys interesting articles on tennis elbow ,I on the other hand suffered golfers elbow playing tennis which I now believe was caused through the purchase of a babolat pure drive. For most beginners or players who don’t have a tremendous amount of strength, this would be a significantly more comfortable racquet to play with, even though it has a stiffness rating that is 5 points higher. Let me know, and I’ll be happy to share a few options. We hope you love this article. Closely related to control, feel, or sometimes referred to as touch, is another characteristic that many players associate with racquets of varying stiffness.

One problem with the number itself, however, is consistency. However, nothing beats getting out there and testing a racquet for yourself. However, nothing beats testing a racquet on the court for a couple of hours to see how it performs. Beyond that, I love that you’re also experimenting with your strings, and Wilson Shockshield is a worthy option for anyone struggling with arm pain. The range or scale for stiffness for racquets will usually fall between 50 and 85, where the lower number indicates a more flexible racquet, and the higher number a stiffer racquet. Un mot de passe vous sera envoyé par email. You might be surprised at how much it bends. However, when the ball impacts the racquet it is a dynamic, instantaneous event, and the amount of racquet deflection depends on both its stiffness (elastic restorative force) and mass distribution. It’s a multifilament, and this category of strings is the best for anyone struggling with arm pain. No tournament wants to be seen as negligent. What you feel (all that you feel) is the racquet thump (shock) and vibration in your hand.

Discussion Boards Join the conversation with other members of the community. Here are links to the resources I reference in the video: In the following sections, I go deep to explore the topic of stiffness and flex – I hope you enjoy it! How could Stan brake one easily like the photo, I wondered when I saw the video clip. However, these machines are not easy to come by, so the easiest way to get a wide variety of the specifications is to check your favorite online retailer, as they typically provide this measurement for comparison purposes. For this same reason, control racquets, also known as player’s racquets, tend to have more flexible frames, resulting in less power potential for the racquet but greater overall control. It is also wise to ‘grow into’ a frame vs getting immediate impact if at rec / still improving level, or else you will constantly want to change bc Power becomes less and less desirable…….. How is Tennis Racquet Stiffness Measured? As a result, senior players or those with elbow and wrist issues tend to choose a flexible frame, exchanging lesser power for improved arm health. A more flexible frame can give players the perception they're hitting dead spots on the string bed, where the ball has less pace and depth. The Yonex EZONE 98 is a great racquet, which will have a softer, more muted feel. In terms of comfort, because they bend and absorb more shock on impact, flexible racquets are generally considered more arm-friendly. Consequently, a stiff tennis racquet will flex significantly less during a swing and deflect more energy or power.

The site primarily focuses on the men’s game with a bias towards Roger Federer but also covers the financials of the sports, equipment reviews, strings, and every tournament at Grand Slam, 1000, and 500 level. https://t.co/SREKwTRiHL, RT @C1aranMurray: A victory for PCR truthers? The RDC machines calculate stiffness by applying force on the hoop of the frame while it's locked in at the handle and resting on a bar near the throat area which acts as a lever. Do you still have questions? Required fields are marked *. If you're in the market for a new tennis racquet, then one of the specifications you'll see listed by retailers is the ‘stiffness' of a racquet. Do you know what RA rating Fed’s magic wand is? But one thing this pandemic was not, it was not a waste of time. In my case I have an aero pro drive racquet and since I started using it tennis elbow and shoulder issues started too. Thanks for stopping by and sharing. What worries me is how easy the people gave up their liberties unquestionably to the governments. Un média de LEOPARDS GROUP. Anyone seen Stan’s funny videos? The stiffness of the racquet impacts the amplitude, frequency, and how much those vibrations are dampened. And the softer and heavier the racquet, the slower the frequency, the longer the period and the greater the amplitude. Recieve our brief weekly recap of the 5 most interesting things we dig up in world of tennis. I can’t find the SI for Fed’s racquet though, not sure they publish it. The more it flexible a racquet is, the more it bends and the more energy it absorbs. Finally to bring this whole pandemic conversation to a final conclusion, here it is. I do not know it ok or not.

The number allows you to quickly benchmark which frames are considered stiff or flexible, demo them and see which you prefer, assuming all other specs are similar or equal. The stiffness of a racquet impacts a racquet's playability in three areas: Without going deep into the physics of it, the reason stiffness impacts the power of the racquet is due to energy transfer. Maybe Jonathan and people that agree that this has been overblown and I hope they are right, time will tell. You can see an example of Wilson's stiffness measuring technique in the video below. Instead, control is primarily a function of a player’s skill and technique, which, combined with a flexible lower-powered racquet, allows them to dictate the placement of the ball more accurately. The first peak is the combined shock and vibration. On the other end of the spectrum, here are a few racquets that feature ultra-low stiffness ratings. This graph shows the acceleration of this spot as it changes its motion back and forth. This can allow an opponent to mop up on your short balls, ending points quickly. Combined with your multifilament string NRG2, it should be a solid combo.

Wilson's method is more realistic for how a racquet reacts during match play as the clamp is essentially replacing the hand. He said he could always do that as a last resort and he wanted to give us our OWN responsibility. Time will tell if they were correct. The amplitude of each vibration is greatest for impacts near the tip and throat. As a result, the more flexible a frame, the more energy it absorbs, which results in a loss in power when hitting. Frame stiffness is one of many criteria that can help players make an educated decision selecting a racquet. Yeah I agree it’s not great how quickly people fall into line without asking more questions and getting data not just accepting someone saying “stay at home”. I’d written it off long ago with how this was going. The less is known, the more is speculated and it does seem like those decisions that have huge implications have been made on people wanting to ‘do the right thing’ but with very little data to do so. While you cant measure racquet flex to get an RA number at home, you can get an idea of the flex by lying it flat against a surface and pressing down on the throat to see what give it has. http://www.africatopsports.com.

With each racquet you play with, you’ll gain more perspective, which you can use as a reference for future comparison. The RDC machines calculate stiffness by applying force on the hoop of the frame while it's locked in at the handle and resting on a bar near the throat area which acts as a lever. Le continent européen à été mouvementé par les deux grandes compétitions des clubs durant deux jours en ses tours préliminaires, le congolais...

Whereas power is easily explained by physics, control is a more subjective area and varies from player to player. Not every manufacturer uses a Babolat RDC machine, and they are not all calibrated the same way. Bending is directly proportional to the degree of stiffness, for the obvious reason that stiffness is, by definition, resistance to bending.
