Benefits in racquets of the nineties:
Tennis coaches and very avid tennis players, through trial and error, have developed a good understanding of frames and suitability. Many people, however, do not have the luxury of time and experimentation. In order to explore what could happen to a person who does not have a very extensive tennis background, I recently visited a very well known sporting goods store in Canada to perform an experiment. I walked into the racquets department and proceeded to ask for help in choosing a tennis frame. The sales person was very enthusiastic and immediately brought me two frames. The first frame apparently created loads of topspin and was an unbelievable racquet. So, I asked how the frame could create so much topspin. The answer given was that the frame was very light and that the strings could really bite into the ball, producing the spin. I smiled and asked about the next frame. The next frame apparently was full of power and could create amazing speed on the ball. I asked him how the frame was able to do that. He said that it was quite stiff and that no energy was lost when the racquet made contact with the ball. I smiled and then thanked him for his time. What did I learn from my ten minute visit, and how could it effect a person who did not know racquet technology? First of all, the first racquet (name intentionally withheld) shown to me was extremely light, very thin, and flexible. I can understand how a player could swing and have the potential for great racquet head speed. When contacting the ball, this would create great spin speeds. The salesperson neglected to tell me that the lightness of the racquet could cause problems in receiving hard and heavy hit balls. To clarify, mass in a frame is important in order for the speed of incoming balls to be diffused or dampened at the point of impact. This means that a player with an arm outstretched and far from his body could take the shock and impact energies directly into the arm segments. Some people may argue that the lighter frame does enable the creation of racquet speed which will, in itself, counter the effects of the fast incoming ball. So, what happens when you return someone's bullet serve? Players using this very light racquet will always need to take a full swing in order to avoid shock. Balls today are hit so much harder that players must stretch and block back many shots, thus some mass is needed for stability. The next frame (name also withheld) was indeed powerful and, if used properly, could create speed. But, the stiffness of the frame was not explained to me in enough detail. The frame was made of kevlar and other composite materials, had some mass, and was very stiff. The salesperson neglected to tell me the reasons why the frame was so powerful. Power ratings are often determined by manufacturers using machines that measure loss of energy when a tennis ball contacts the frame (flexibility). Energy is lost when a frame flexes, so the stiffer the frame the more powerful its label, and vice versa. My analysis was that the frame was very stiff and, because of this stiffness, the head and throat had very little flex. A frame that does not flex is powerful because that energy is not lost at the point of impact. In the past, wooden frames would flex and energy would be lost upon impact, along with some control. So what happens to the shock impact? Much of the impact is absorbed in the next closest segment, which is the wrist or elbow. Yes, the "sweetspot" takes some of the shock but most of the force is directly transferred to the arm. The result is often a tennis-related injury such as tendonitis. Professional players can use stiff frames with more safety because their forearms (extensors and flexors) are extremely strong and can withstand the shocks created.
Biomechanical Development vs. The Role of the RacquetMany people do not understand that the physical abilities and the state of physical maturation of a player should determine the choice of racquet. If a young player is still not fully physically developed, she may need a racquet and string tension able to create speed and power. As the player grows physically, and the biomechanical linkages become more efficient, the racquet will be used less as a power source. A common problem is that many people are afraid to use their full physical, biomechanical linkages because they use too powerful of a frame. The racquet should be used in coordination with a person's physical attributes or shortcomings. You will notice that many stronger professionals use less powerful, flexible frames while others, who are weaker, will use stiffer, more powerful frames. Bottom line - as a tennis player develops in skill, the frames that are used must compliment this overall development rather than overshadow it.
Customizing Tennis FramesIf you look very carefully at the racquets of many tennis professionals, you will notice that there are many alterations, some easily seen. Here are some of the ways in which players customize their frames:
In conclusionDo your homework when selecting a tennis frame, take your time. Speak with a local tennis professional who knows your game. They should be able to help. When a frame is recommended, use it for several days in order to develop a feel for the frame's playability.As a general guideline, young juniors who are beginners should be using very flexible frames, and more advanced juniors should use less flexible frames. Stiff frames are recommended for players who are physically mature and who have proper biomechanical linkages in most strokes. Lastly, always try to choose a frame for the right reasons, and never just because Pete, Andre, or Monica uses it. If you have any equipment or developmental questions please feel free to contact me.
