About the Authors

Preface



This book is written for serious competitive and recreational tennis players.



Many tennis books emphasize fitness or strength and conditioning. Tennis

Anatomy takes the next step and focuses on why and how you should get fit to

play tennis. In this book, we highlight the different muscle groups involved in

each of the strokes and show you how to best train those specific muscle groups

as part of a comprehensive approach to tennis-specific training.



   With the support of the United States Tennis Association (USTA), we

provide the most up-to-date, relevant information on tennis conditioning

available. As the national governing body of tennis in the United States, the

USTA has a responsibility to grow and develop the sport. Through its player

development program, the USTA shares the latest training techniques with

competitive players in the United States. That mission encouraged us to take on

this project and provide you with these training methods based on the anatomy

of tennis.



   Tennis was once considered a sport that could be played by people from age 8

to 80, but that range has expanded because of new training methods. The USTA

offers 10 and Under Tennis for players age 10 and younger, who learn the sport

while using modified equipment. In addition, national-level tournaments are

offered for players age 90 and over. This shows the tremendous health, fitness,

coordination, and psychological benefits that can be derived from the sport.

Clearly, being a well-conditioned tennis player can assist in a long tennis career.



   Of course the number of years someone can play is only one aspect of

enjoying the game. The quality of play also is greatly enhanced by good training

and conditioning. That is the true focus of this book. Whether you are getting in

shape for league play, trying out for a high school or college team, or wanting to

perform at a higher level in tournaments, this book provides you with up-to-date,

practical training information based on the latest research available.



   The first chapter provides an in-depth overview of the demands of the sport,

the relationship of court surfaces and playing styles, the anatomy of each of the

tennis strokes, and the physiological considerations of designing a training

program. Chapters 2 through 7 systematically explain the role of each major

body part in tennis play, focusing on muscle anatomy and its relationship to the

strokes and providing specific exercises. Each exercise includes a tennis focus

section that highlights how the exercise directly translates to improved on-court

stroke performance or movement. Chapters 8 through 10 follow a similar format

but highlight the importance of body rotation, movement skills, and injury

prevention, respectively. The anatomical illustrations that accompany the

exercises are color coded to indicate the primary and secondary muscles featured

in each exercise and movement.



   You will enjoy and benefit from this information. Challenge yourself to learn

more about the anatomy of your body as well as the tennis strokes, and improve

your game by adding tennis-specific conditioning methods to your training. By

incorporating these training techniques, you will surely be able to take your

game to the next level.

Acknowledgments



This book would not have been possible without the dedication, coaching, and



support we have received over the years from the many sport science and

medicine experts that have crossed our paths. All of our thoughts and ideas have

been shaped by these dedicated people through courses, individual meetings,

publications, and conferences. We cannot begin to name all of them, but we are

truly indebted to them.



   Another group of people instrumental in our lives is the many coaches and

tennis teaching professionals who have taught us and helped us in the areas of

player training as well as coaching education.



   Human Kinetics came up with the idea and pursued our interest, and the

United States Tennis Association (USTA) allowed us to take on this project. We

very much appreciate the opportunity both organizations provided us. The Boca

West Country Club made their tennis courts and fitness facilities available to us,

for which we are very grateful.



   Finally, we would like to thank our families, particularly Paul's wife,

Barbara, and Mark's wife, Mary Jo, for their support and encouragement.

Chapter 1



The Tennis Player in Motion



Elite tennis players make it look so easy and effortless. By comparison, your



movement skills, strokes, and fitness may leave something to be desired. Good

coaches can help you improve technique and fitness, but keep in mind that there

are many individual differences, even at the professional level. You can see that

Roger Federer and Rafael Nadal don't play exactly the same way. They do have

in common a desire to perfect their skills and a drive to continue to improve both

technique and physical preparation. Proper technique, however, can be attained

only if you can produce all necessary movements throughout the range of motion

required for optimal positioning and stroke execution.



   The sport of tennis requires strength, flexibility, power, endurance, and speed.

Each of these components requires a well-trained muscular system. In addition,

each court surface provides a different challenge. For example, clay courts

require players to play longer rallies--sometimes as much as 20 percent longer

--than do hard courts, and grass courts are even faster than most hard courts.

Therefore, players who usually play on clay should train muscular endurance,

while players who usually play on faster surfaces such as hard or grass courts

may want to train more for muscular power or at least a combination of

endurance and power.



   Tennis is a lifelong sport, and the goal for many of us is to continue to

enhance our performance while staying injury free, whether playing

recreationally, in tournaments, at the college level, or even at the professional

level. The best way to do this is to train effectively and use proper technique,

seeking to produce effective and efficient tennis strokes. Consider the demands

of tennis, but keep in mind your unique playing style and body structure.



Physical Demands of Tennis



Proper movement skills are critical for successful tennis. A successful tennis

player must be able to get to the ball early and set up properly. Typically, this

requires quite a few adjustment steps as you recognize the path, spin, and pace of

the incoming ball. In fact, tennis often has been characterized as a game of

emergencies. It involves constant movement, short sprints, and frequent

directional changes. On average, 3 to 5 directional changes are required per

point, and it is not uncommon for players to perform more than 500 directional

changes during a single match or practice. Matches can last several hours, which

requires aerobic fitness, but the short sprints, explosive movements, and

directional changes are clearly anaerobic. Therefore, both the cardiorespiratory

and muscular systems should be trained using movement patterns representative

of those seen during tennis play.



   A big focus of the United States Tennis Association (USTA) Player

Development training program is good movement and positioning. It is clear that

if you can't get to the ball and set up properly, you won't hit the ball in the most

balanced way to produce a forceful stroke. The legs are the first link in

transferring forces from the lower to the upper body. This is part of the kinetic

link, or kinetic chain, system. Newton's third law states that for every action

there is an equal and opposite reaction. When you hit a tennis ball, your feet

push against the ground, and the ground pushes back. This allows you to transfer

force from one body part to the next, through the legs, hips, trunk, and arm all

the way to the racket. The key is to do this in the most efficient and effective

manner by timing the segments correctly, not leaving out any segments, and

preparing your body to be strong and flexible enough to handle the stresses

imposed. Proper technique and preparation of the muscular system should go

hand in hand. The lower body, midsection (the core or torso), and upper body

are important in tennis, but each segment has different needs and training

requirements.



   Training the legs is vital for efficient movement on the court. Research shows

that the muscles in both legs are stressed equally in tennis, so training programs

should reflect this. Since the vast majority of tennis movements are side to side,

it is important to focus 60 to 80 percent of training on these movement patterns.

In other words, working on lateral movements incorporating the abductors, the

muscles that move the leg away from the center of the body, and the adductors,

the muscles that bring the leg toward the center of the body, is at least as

important as training the other muscle groups of the legs.



   Think of the midsection of the body as a cylinder when it comes to training.

Exercises should be designed to move the front, back, and side of the torso

through multiple planes of motion. Tennis strokes require rotational movements

as well as flexion and extension, frequently all in one stroke.



   The dominant side of the upper body is much more involved in each stroke

than the nondominant side. Therefore, in addition to training the dominant side

for performance purposes, you need to train the nondominant side for balance

and injury prevention. Since the game tends to be dominated by serves and

forehands that involve the muscles of the front of the shoulders and the chest, be

sure to train the muscles in the rear of the shoulders and the back. During

forehands and serves, these muscles experience eccentric, or lengthening,

contractions and shorten during the backhand stroke through concentric

contractions.



   When designing a training program for tennis players, it is important to

balance upper and lower body, left and right sides, and front and back. Tennis

Anatomy takes you through each of the body parts and provides you with

appropriate exercises for optimal performance.



Playing Styles and Court Surfaces



Muscular balance is key for all players regardless of surface or playing style.

However, your playing style and the surface you play on most often will

influence your training goals and affect your exercise choices. For example, if

you play a lot of long points on clay courts, you will want to train for endurance,

especially in the lower body, instead of muscular strength and power, which

would be more appropriate for a player who plays shorter points on hard courts.

The same principle holds for the upper body, but to a lesser extent. You will still

likely hit the ball just as hard when playing on a slower court; however,

muscular endurance becomes more important since the points are longer.

Regardless of playing style or surface, the upper body should be trained for both

muscular power and endurance.



Playing Styles



Do you know what your playing style is? Do you like to come to the net and put

the ball away with a volley or overhead? Or are you the type of player who likes

to outlast your opponent by never missing a ball? Or do you like to hit the ball

hard from the baseline, trying to dictate points and go for winners? All three

styles can be very effective. Which style you use depends on your skills,

personality, and possibly the court surface you play on most frequently. Most

coaches categorize players into four different playing styles:



  1. Serve and volleyer

  2. Aggressive baseliner

  3. Counterpuncher

  4. All-court player

At the top professional level, the aggressive baseliner is the most prevalent,

followed by the all-court player. The traditional serve and volleyer and the

stereotypical counterpuncher are no longer preferred playing styles on either the

men's or women's tours. However, tennis players at other levels can be seen

playing each of these different styles.



   The serve and volleyer (figure 1.1, page 4) relies on the serve to help dictate

the point. After the serve, she explodes forward to the net. Typically, a serve and

volleyer moves forward 20 to 40 percent more than a counterpuncher or an

aggressive baseliner and about 20 percent more than an all-court player. Because

of this forward movement, a serve and volleyer often finds herself at the net,

trying to finish the point. Good volley technique is imperative and requires

excellent leg strength, particularly in the quadriceps, gluteus maximus, and

gastrocnemius. Strong leg muscles are key, especially for hitting low volleys that

require significant knee flexion. Functional flexibility is very important to the

serve and volleyer because she is required to get very low to the ground dozens

of times throughout the match. Similarly, flexibility of the wrist is helpful,

especially in reaching for volleys that stress the end range of the joint. This

flexibility needs to be trained regularly.



                        Figure 1.1 Serve and volleyer on a grass court hitting a low volley.

   The aggressive baseliner (figure 1.2, page 4) is more comfortable hitting

groundstrokes but is also looking to put pressure on his opponent by hitting hard,

aggressive strokes. This player's goal is to move less than the counterpuncher,

and he prefers to move inside the court and take balls earlier to reduce the

opponent's time between strokes. Muscular strength and endurance are required,

but overall power is the major physical component that helps the aggressive

baseliner dictate points. Having a major weapon such as a big forehand or strong

two-handed backhand is very beneficial. Powerful strokes require strength as

well as speed. Training exercises should take this into account. Exercises for the

lower body and midsection should be very similar to those mentioned for players

with other styles, but a greater emphasis on upper body power is helpful. The

muscles of the chest and front of the shoulders are important for producing force,

but don't neglect the muscles of the back of the shoulders and upper back. They

help protect the shoulder complex and prevent injury.

                 Figure 1.2 Aggressive baseliner on a hard court hitting a two-handed backhand.



   The goal of the counterpuncher (figure 1.3) is to chase down every ball and

make sure the opponent has to hit many balls each rally to win any points. This

game style is based on great side-to-side movement and stroke consistency. The

counterpuncher moves laterally 60 to 80 percent of the time. Often she will

stretch out to hit open-stance forehands or backhands. Therefore, it is critical to

train the abductors and adductors as well as the muscle groups mentioned for the

serve and volleyer in a well-rounded training program. This includes training

flexibility as well as strength. The counterpuncher must depend on speed,

quickness, and the ability to change direction since she may not often put the

ball away for a winner. This type of game style is most effective on slower

courts. Muscular endurance of the upper and lower body is critical. The obliques

must be trained to assist in the rotational movements of all groundstrokes since

the counterpuncher hits so many strokes, most with an open stance. Also, when

playing great defense, the counterpuncher may hit many strokes when on one

leg, out of position, or off balance. Therefore, it is imperative to train for these

situations on the court by performing single-leg activities and training in

unstable or irregular environments.



                     Figure 1.3 Counterpuncher on a clay court sliding to hit a wide forehand.

   The all-court player (figure 1.4, page 6) looks to be aggressive when hitting

groundstrokes but is also happy to follow aggressive shots to the net to finish

points. All shots, from serves to groundstrokes to volleys, require equal attention

in training. In addition, significant time should be spent on the transition game,

training for shots that help the all-court player get to the net. The all-court player

should regularly practice approach shots, such as a big forehand or slice

backhand hit from half court, and follow each shot to the net. These shots require

excellent movement and positioning, most often with a more closed stance than

regular groundstrokes. Exercises for both the upper and lower body are

beneficial, especially exercises that help develop weight transfer and movement

into the court such as the spider drill (page 174) and the split step with stimulus

drill (page 177) in chapter 9. It is important to train all muscle groups. The main

focus should be on balancing between left and right, front and back, and upper

and lower body.

  2. Rotate the hands out approximately 2 to 3 inches (5 to 8 cm) while turning

      your thumbs out, and then retract the shoulder blades. Hold this position

      for two or three seconds. Push your chest forward as you retract the

      shoulders.



  3. Return under control to the starting position.



Muscles Involved



  Primary: Trapezius, infraspinatus, rhomboid major, rhomboid minor

  Secondary: Latissimus dorsi



Tennis Focus



Because many overuse injuries occur at the shoulder joint, it is important to

strengthen the rotator cuff as well as the scapular stabilizers. These muscles

often work eccentrically, in particular during the follow-through phase of serves

and forehands. This exercise will improve the integrity of the shoulder girdle by

working the muscles in the opposite direction of their tennis function, which is

concentric. Additionally, this particular exercise will help with proper posture,

which is also a concern for many tennis players because of the repetitive nature

of the sport.
