THE TENNIS SERVE
The Tennis Serve consists of three main phases: 1) the backswing, 2) the forward swing and 3)
the follow through.
Each phase will be broken down for the right-hand player and the most
important muscles contributing to each phase will be identified. However, before any of these
phases are performed, getting into the proper stance is required.
Therefore, let’s first identify
the basic stance position for the tennis player.
The Stance.
The front foot is directly behind the baseline angled diagonally into the court.
The back foot is near parallel to the baseline and is situated behind the front foot. Both feet are
about shoulder width apart and the majority of the weight is on the front foot with the back foot
used mainly for balance.
The racket is pointing directly at the net and the ball is held against
the throat of the racket. This is the basic stance position and is seen in Figure 1-7a.
The Backswing.
The backswing transitions us from the stance position seen in Figure 1-7a to
the trophy pose position seen in Figure 1-7d.
During this transition, three noticeable movements
take place at the same time, and they are:
1) the motion of the tossing arm,
2) the motion of the
racket arm and
3) the transfer of weight between the feet.
1) Motion of the Tossing Arm.
Generally speaking, both arms drop together (Figure 1-
7b) and then rise up together (Figure 1-7d).
Focusing on the tossing arm, the muscles that allow
for this upward movement in Figure 1-7c are the Coracobrachialis, Biceps Brachii, Anterior Deltoid and Pectoralis Major.
2) Motion of the Racket Arm.
From the stance position in Figure 1-7a, the racket arm
drops down and is then abducted out to the side of the body with the palm of the hand facing
downward (Figure 1-7c). The primary muscle responsible for abducting the racket arm out to
the side is the Middle Deltoid.
Now if we continue on with the motion of the
racket arm, we end up in a position called the “L” position (Figure 1-7d) because the racket arm
and forearm end up making the shape of the letter “L” and this position is necessary to allow
you to swing the racket correctly later on in the serve.
The muscles that help get your racket
arm into this position are collectively known as the external shoulder rotators and their names
are the Teres Minor and the Infraspinatus muscles.
3) Transfer of Weight Between Feet.
The other noticeable movement that occurs in
going from the stance position to the trophy pose position is the transfer of weight that occurs
between your feet. Beginning in the stance position in Figure 1-7a, the majority of weight starts
out on the front foot and the back foot is used mainly for balance. Figure 1-7a shows this with
the front foot flat on the ground and the heels of the back foot slightly elevated.
Balancing in
this position is a function of the hip stabilizer muscles on the left side of the body.
From there, your weight rocks back on to your back foot and now the toes of your front foot
come up off the ground (Figure 1-7b).
Your weight then rocks back forward (Figure 1-7c) and
while this is happening, both knees start to bend - a function of the Quadriceps muscles.
The heels of your feet also start to rise up off the ground - a function of the
Ankle Plantar-flexors.
As you continue to rock forward, your back foot is brought inward, or adducted by the
Adductor muscles , toward your front foot and you end up in the trophy pose
position signifying the end of the backswing (Figure 1-7d).
Here, both knees are bent, ankles
are plantar-flexed, racket arm is in the “L” position and the tossing arm is pointing up.
