Tennis Racquet Stringing Options for Competitive Juniors

Goran Vukovic

Why do so many of Alberta’s top competitive junior tennis athletes and their parents choose to string at Racquet Network?

Probably because our expert staff and coaches work with parents to protect the health of their junior athletes.

Keep in mind that we have been working with junior tennis players and their families since 2004. Over the years, we have watched these junior athletes grow up, compete, earn scholarships, graduate from college and start families of their own. Some of our athletes even have their own children enrolled in tennis programs today.

In spite of the best efforts from these players, their parents and their many coaches over many years, not one of these Calgary hopefuls ever turned pro.

Why? Because this is Calgary. We keep our fingers crossed for all of these kids, of course, but the odds of anybody from Calgary ever turning pro are very slim indeed.

The most common outcome that we have seen over the years are junior tennis players who become young adults with all of the injuries and nagging aches and pains of the pros but none of the accolades.



It breaks our heart to hear about fifteen-year-olds who cannot sleep on their right sides due extreme to shoulder pain.

That’s why our emphasis is always on who-the-athlete-is-right-now, not what-we-want-the-athlete-to-become.

Our experts never recommend that juniors use the same strings or racquets that adult pros use. Both of these are way to stiff for undeveloped muscles and joints and can lead to persistent injury and chronic pain.

Our advice to juniors is to stay away from these things until they are adults. In the meantime, use gear that is designed for athletes their age.

Polyester strings are a great example of this. Pros use polyester because their swings are extremely fast. The top players in major tournaments can also have tens of thousands of dollars riding on a single swing of the racquet. So they cannot risk having a string break at an unexpected moment.



Juniors under 14, even the best of them, are not as strong as adults. They don’t need polyester strings. Moreover, the long term injury effects of using polyester strings at too young of an age are well documented.

Our advice to junior players and their parents is to stick with multifilament string until they turn 14 or until they are swinging so hard and breaking string so often that they have no other choice.

In the meantime, Racquet Network has developed a graduated stringing program with ten different levels. Level 1 starts juniors off with soft thin string suitable for 8-10 year olds. Each succeeding level above Level 1 has slightly more durable string. The final level, Level 10 has the most durable multifilament string we can find.

Most new players entering the program start at Level 1. If the string at that level lasts for two weeks, then we consider it the right level. If not, then they move up a level and they keep moving up levels until the reach a combination that lasts two weeks or more before breaking.



Once the find their level, they stay at that level until they outgrow it. Once their swing speed develops beyond that level and they start breaking string again regularly, it’s time to move a little higher on the chart.

The more they play, the stronger athletes get. So if your athlete is breaking strings more often than they were a few months ago, it may be a sign that they are improving and hitting harder. Our level systems helps parents and athletes find the right string combination for their current level. It also gives players who are improving an idea of where to go next.

At every level, our goal is to provide junior athletes with a string that is strong enough to handle their power but soft enough to protect their growing joints and developing soft tissues. This is the best way we know to minimize chronic shoulder pain which many advanced athletes first start to experience in their third year of competitive tennis.

Yonex Releases Astrox 99

Yonex Astrox 99 Badminton Racquet

Yonex Co., Ltd. is proud to announce the ASTROX 99, the newest racquet in the ASTROX series, which continues to gain a never-before-seen level of trust among the world’s top badminton players. Targeted at advanced players, the ASTROX 99 is designed to deliver power from hit after hit. Worldwide release is scheduled for mid-September 2018.

Until now, the ASTROX series has utilized next-generation graphite “Namd” in the shaft, which results in a large increase in the snap back speed of the shaft, producing greater smash speeds. But the ASTROX 99 has adopted Namd in the entire body of the racquet, including the frame, doubling contact time with the shuttle*2, resulting in an explosive shot as the racquet returns from flexed to straight at the end of the swing. Additionally, the Energy Boost Cap shape is designed to encourage even more flex in the shaft, further benefiting from the effects of the Namd graphite.

The series trademark technology, Rotational Generator System, which contributes to a smooth transition from shot to shot also helps the player maximize the effects of the entire Namd body.

The design of the ASTROX 99 is inspired by the power and energy of the sun. The base of orange and black echo the sun spinning in the vast blackness of space, while red highlights recall the explosive solar flares that occur on its surface.

*1 Namd is a technology developed by Nitta Corporation to “uniformly disperse carbon nanotubes into carbon fiber composites.”
*2 Based on machine test results, compared to conventional racquets

INNOVATION

New dimension graphite Namd

A world-first, new dimension graphite material, Namd, greatly improves the adhesion of the graphite fibers and resin by attaching nanomaterial directly to the graphite fiber.

In high performance racquets, it is common to combine nanomaterials with resin that connects graphite fibers, but in Namd, nanomaterials are directly adhered to the graphite fibers and resin is greatly increased. This major improvement produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle. In the ASTROX 99, Namd has also been incorporated in the racquet frame, which helps it to “hold” the shuttle, increasing contact time and, resultingly, the speed and force with which it is expelled.

Below left: A shuttlecock hit by the ASTROX 99 reaches the target fast and penetrates deeper than when hit by a conventional racquet.

Below right: The contact with the shuttlecock is twice as long with the ASTROX 99 than with the conventional racquet, and the shuttle is ejected faster and further.

Rotational Generator System

By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control. The transition to the next shot can be performed smoothly and in rapid succession.

New Cap Design “Energy Boost Cap”:

Maximizes shaft performance

The new shape allows the shaft to flex, which ensures the maximum effect of “Namd[1](more flex and faster kick-back graphite material)” and stabilizes the racquet face by preventing the shaft twisting, increasing control.

Which Yonex Astrox is Best for Me?

Yonex Astrox Flash Boost Badminton Racquet

Which Yonex Astrox is Best for Me?

There are several racquets in the Astrox series for men, women and teens at all levels. This provides an overview and a starting point for considering which are good fits for you.

Overall, this is a head heavy series. It replaces the old Voltric series which is now obsolete.

The Astrox series features upgraded materials and enhanced engineering. But like the Voltric series before it, the Astrox series is designed for players who like to smash. It is also for players who who tend to hit most of their shots from the middle to the back of the court.

Chart produced by Yonex summarizing their Astrox series of badminton racquets
Enlarge this chart to see what Yonex recommends for their Astrox series.

Advanced to Elite Players

Big, strong and/or athletic players who are fully capable of hitting out of bounds from any where on the court tend to play with stiff and extra stiff shafts. The racquets in the Astrox series with stiff and extra stiff shafts are the Astrox 99, Astrox 88D, Astrox 88S, and Astox 9.

Players in this group tend to be in the top 10% of all players. Most are men, but some ladies and elite teens fit into this category as well.

Intermediate to Advanced Players

Recreational players who are not capable of hitting the backhand corner to corner clear out of bounds with a stiff racquet may will usually choose to play with racquets with medium flex shafts. The Astrox series racquets with medium flex shafts include the Astrox 77, Astrox 7 and Astrox 55.

The group of players includes most recreational level men who play regularly, stronger recreational level women, advanced teens and advanced seniors.

New to Intermediate Players

This category includes most recreational level ladies, teens and seniors. Players in this group have difficulty hitting the shuttle out the back of the opposition baseline when standing on their own baseline, especially on the backhand. Astrox series racquets built for this group included Astrox 66, Astrox 6, Astrox 5 Astrox 2.

Save Money with Pressureless Tennis Balls

BABOLAT ACADEMY PRESSURELESS TENNIS BALLS
Save money. Use pressureless tennis balls.
As you can imagine, we spend a LOT of time hanging around tennis courts. Therefore, we spend a lot of time watching recreational tennis players. And as a result of this, we can tell you that most recreational players are playing with the wrong tennis balls.

We are not talking about color coding here. That’s a different issue. We are talking about regular players playing with regular tennis balls. Most of them are wasting their money and wasting their time playing with regular, pressurized tennis balls.

Regular tennis balls come in a can. That can is pressurized to 15 lbs per square inch over ambient air pressure. This is why it sounds like a soda when you pop the seal and open a new can of balls.

Just as a soda starts going flat the from the moment you open the can, tennis balls start going flat, too. From the moment you open the can, the balls inside start losing pressure. If you drop a new ball when you first open the can, it will bounce up to your belly button. Wait just two weeks and the same ball — even if it sits unused in your bag — will only bounce up to your knee.

This is because as soon as you open the can, the balls start losing air pressure and begin returning to balance with their new environment. Here in Calgary, this means that new tennis balls lose about 50 per cent of their bounce in about a week — even if you don’t use them.

Unless you are playing several times per week, pressureless tennis balls are not a wise way to spend your money. As we said above, even if you don’t use them, they will quickly go flat in your bag. A much better way to go is to purchase pressureless balls. Pressureless balls never lose their bounce. You can leave them in your bag all winter and they will bounce the same in the spring.

Pressureless balls use new materials technology to maintain their bounce. And contrary to popular belief, pressureless balls do not weigh any more or less than standard pressurized tennis balls. Today in our store, for example, we weighed six different models of pressurized and pressureless balls and all weighed exactly the same — 58 grams.

So unless you are tournament player who has to be accustomed to a very specific ball, there are almost no good reasons to be using old fashioned and expensive pressurized tennis balls.

Babolat ™ Academy balls are available in our southwest Calgary store. They can be purchased individually or in money-saving multiples. They are designed for use in teaching programs and ball machines, so they are extremely durable and long lasting. For most infrequent players, this is the best way to go.

We also offer a range of pressureless tennis balls for children, teens and adult beginners.
