Backhand
Block
The
backhand block, like the forehand block, uses the speed and spin
that is already on the ball to return the ball back across the
net. The biggest difference between the backhand and forehand
block is the backhand block makes contact with the ball directly
in front of the body; whereas, the forehand block makes contact
with the ball to the side and in front of the body.
Stand about 12 inches in back of the center of your backhand court
(the left court as you face the table, for right-handers) in a
squared off stance as shown in Photo 11 below. Do not turn your
body sideways. Position your body so if you did not hit the ball,
it would hit you squarely in the center of your body. Distribute
your weight equally between both legs. Tilt your upper body slightly
forward so your elbows hang down just in front of the body.
Intercept the ball with a still racket as the ball is rising and
just before it reaches its peak. Angle the racket open or closed
by rotating the forearm to make the ball return low over the net.
If your return is too high, you must angle the racket more closed
by tilting the face of the racket toward the table. Conversely,
if your return is too low and doesn’t clear the net, you
must open the racket angle slightly by tilting the face of the
racket closer to vertical.
Lesson 10: Backhand Block With No
Foot Movement
Adjust
the robot to deliver topspin shots to the middle of your backhand
court at a slow pace and speed. Practice your backhand block in
the same manner and in the same sequence as you did the forehand
block. Start slowly with no oscillation and blocking the ball
back crosscourt, then down-the-line, and finally alternating shots
in the two directions. Gradually build up the ball frequency and
speed. Be sure that you can do, without missing, 50 crosscourt
blocks, then 50 down-the-line blocks, and finally 50 patterns
of alternating crosscourt and down-the-line blocks.
Remember not to swing at the ball. Merely block the path of the
ball with your racket and let the ball’s speed and spin
cause it to rebound across the net. Experiment with tilting the
racket angle downward until you can consistently place the ball
back in the desired direction and low over the net.
Lesson 11: Backhand Block With Foot
Movement
When
you have reached your current maximum limits in Lesson 9, you’re
ready to combine movement with the backhand block. To add movement
to the robot, turn the main switch off and move the sweep control
levers to positions 3 and 6 if you’re right handed or 1
and 4 if you’re left handed. Set the ball frequency and
ball speed controls to 1–2 points below your maximum rate,
as determined in Lesson 10. Adjust the oscillator speed setting
as described on pages 2–4.
The balls will be randomly delivered from the center line of the
table to the backhand corner. Practice blocking the ball back
crosscourt with your backhand until you are consistent, then practice
down-the-line blocks, and finally alternate crosscourt and down-the-line
blocks, all with the ball moving to random positions within your
backhand court at slow speed.
Always move your body directly in front of the ball before the
ball is thrown towards you. Avoid reaching for the ball with your
arm—MOVE YOUR FEET! Keep your elbow out in front of your
body; don't let it hang at your side. It helps to watch the robot
head to see which direction it is going to shoot so you can move
into position before the ball is thrown to you.
Once you complete this sequence at below maximum speed and frequency,
gradually turn up the ball speed and ball frequency controls until you reach the upper limit of your
current ability without losing consistency.
